Use of agro and industrial wastes in concrete production will cause sustainable concrete era and greener habitat. In this study an endeavor has been made to discover the propriety of Sugarcane Bagasse Ash (SCBA) and Granite Waste (GW) as partial replacement for traditional river sand. The percentage substitute is calculated based on the particle packing approach. The properties such as compressive, splitting tensile, flexural strengths and modulus of elasticity, water absorption, sorptivity and rapid chloride penetration test of the concrete with bagasse ash and granite waste as a partial replacement for river sand and to evaluate them with those of conventional concrete made with river sand fine aggregate are investigated. The test results show that the strength aspects of bagasse ash-granite waste concrete are higher than those of the conventional concrete. Moreover, they suggest that the bagasse ash-granite waste concrete has higher strength characteristics and remains in the lower permeability level shows improvement in overall durability of concrete than the conventional concrete.

This paper presents an experimental investigation on the properties of concrete in which like cement is partially replacing by used nano silica and is partially replacing by used waste foundry sand. Because now a day the world wide consumption of sand as cement and as fine aggregate in concrete production is very high. Nano silica and waste foundry sand are major by product of casting industry and create land pollution. The cement will be replaced with nano silica and the river sand will be replaced with waste foundry sand (0%, 5%, 10%, 15%, 20%). This experimental investigation was done and found out that with the increase in the nano silica and waste foundry sand ratio. Compression test has been done to find out the compressive strength of concrete at the age of 7, 14, 21, and 28. Test result indicates in increasing compressive strength of plain concrete by inclusion of nano silica as a partial replacement of cement and waste foundry sand as a partial replacement of fine aggregate.

The increase in the demand for concrete production for the development of infrastructures in developing countries like Ethiopia leads to the depletion of virgin aggregates and high cement demand, which imposes negative environmental impacts. In sustainable development, there is a need for construction materials to focus on the economy, efficient energy utilization, and environmental protections. One of the strategies in green concrete production is the use of locally available construction materials. Scoria is widely available around the central towns of Ethiopia, especially around the rift valley regions where huge construction activities are taking place. The aim of this paper is therefore to analyze the suitability of scoria as a fine aggregate for concrete production and its effect on the properties of concrete. A differing ratio of scoria was considered as a partial replacement of fine aggregate with river sand after analyzing its engineering properties, and its effect on the mechanical properties of concrete were examined. The test results on the engineering properties of scoria revealed that the material is suitable to be used as a fine aggregate in concrete production. The replacement of scoria with river sand also enhanced the mechanical strength of the concrete. Generally, the findings of the experimental study showed that scoria could replace river sand by up to 50% for conventional concrete production.

Purpose In the construction sector, river sand has turned into a costly material due to various reasons. In the current study, used foundry sand (UFS) and spent garnet sand (SGS) are used as a partial and full replacement to sand in concrete production. Design/methodology/approach The objective of the work is to develop non-conventional concrete by replacing river sand with a combination of UFS (constant 20Wt.% replacement) and SGS at various percentages (20, 40, 60 and 80 Wt.%). Findings Compared to conventional concrete, the 28 days compressive strength of non-conventional concrete (with UFS at 20% and spent garnet sand at 20%, 40% and 60% were 8.12%, 6.77% and 0.83% higher, respectively. The 28 days split tensile strength of non-conventional concrete (UFS at 20% and SGS at 20 and 40%) were 32.2% and 51.6% higher, respectively. Research limitations/implications It can be concluded that 60 Wt.% of river sand can be combined replaced with 20 Wt.% UFS and 40 Wt.% SGS to produce good quality concrete whose properties are on par with conventional concrete. Practical implications The results showed that combined SGS and UFS can be used as a partial replacement of river sand in the manufacturing of concrete that is used in all the applications of construction sector such as buildings, bridges, dams, etc. and non-structural applications such as drainpipes, kerbs, etc. Social implications Disposal of industrial by-product wastes such as SGS and UFS affects the environment. A sincere attempt is made to use the same as partial replacement of river sand. Originality/value Based on the literature study, no work is carried out in replacing the river sand combined with SGS and UFS in concrete.

As stated in the European Commission’s waste framework directive, the geographic proximity of wastes to the potential recovery/disposal site is of paramount importance in attaining an effective resource recycling paradigm. The global interest in achieving an end-of-waste scenario encourages the recovery of useful products/secondary raw materials from locally available waste materials. Sugarcane bagasse ash is an abundantly available waste (44,200 tonnes day–1) from sugar plants in India which has the potential to be used as a partial replacement to cement in ready-mix concrete plants. Although pozzolanic performance of sugarcane bagasse ash and its ability in reducing the carbon emissions associated with concrete production have been reported in earlier research studies, its use in concrete is hindered due to the lack of availability and accessibility data. In this study, the geographical distribution of sugar plants and the available quantity of sugarcane bagasse ash in India have been determined. In addition, a detailed network analysis using a geographic information system was conducted to quantify the geographic proximity of bagasse ash, fly ash and slag sources to ready-mix concrete plants. The study results indicate that for most of the ready-mix concrete plants in India, the probability of having a bagasse ash source in proximity is higher than the probability of encountering slag/fly ash sources.


In recent days, there is an intense need for an alternate cost effective and sustainable raw material for concrete which does not make the structure inferior in strength. An experimental study on the utilization of the waste plastic and M-sand in the place of river sand and aggregate partially was performed in paper. In the scenario of scarcity of river sand due to the territorial government action and restriction of usage because of the eco and environmental consideration, M-Sand is found to be an effective replacement and cost effective material. Concrete specimens were casted with combination of M-sand and plastic waste with 5%, 10%, 15%, 20% and 25% and compared against control mix. Cube test for compressive strength study, cylinder test for split tensile strength study and prism test for flexural strength study were done with the proposed concert mixture. All the specimens and tests were done for different curing period of 7, 14 and 28 days. The results obtained from the proposed mix of concrete are compared with the conventional concrete mix specimen respectively. The replacement of fine aggregates reduces the quantity of river sand to be used in concrete and also plastic fibres are proved to be more economical. Positive performance of the concrete with waste plastic and M-Sand as partial replacement of river sand was observed on all the experiments and found optimal in sustainable and economical performance.


Abstract. To overcome the shortage of natural resources for the production of concrete, many waste materials are used to replace the raw materials of concrete. In this way, bottom ash is one of the major industrial wastes which shall be used as the replacement of materials in concrete production. It shall be used to replace the materials either up to one-third. This review brings out the evaluation of the industrial waste material which can be repeatedly used as a substitution for concrete as fine aggregate. This paper reviewed the use of industrial waste i.e., bottom ash as fine aggregate in the concrete. The parameters discussed were physical, chemical, fresh, and hardened properties of the concrete with partial replacement of bottom ash. By reviewing some of the research papers, concluded that 10-15% replacement of fine aggregates is acceptable for all the properties of concrete. High utilization of natural sources -gives the pathway to produce more industrial wastes which are responsible for the development of new sustainable development.


River sand is the standard form of fine aggregate used in the concrete production. In this present era of rapid urbanization, to meet the increasing demand of natural sand by the construction industry, massive scale depletion of the river bed is being carried out which is causing a considerable negative impact on our environment. Hence it is highly imperative to find sustainable fine aggregates to meet the global demand without disturbing our ecosystem. Copper slag is one such sustainable material which has a promising future to be used as an alternative to river sand. This paper presents a study on finding the optimum dosage of copper slag (CS) as partial replacement sand in preparation of concrete. Further, as part of durability study, the impact of elevated temperature of 2000 C, 4000 C and 6000 C for 4 hours exposure period on strength characteristics of copper slag blended concrete has been presented and been compared with that of normal concrete. The results indicate that copper slag concrete has excellent resistance to weight and strength loss at an elevated temperature of 2000 C, 4000 C compared to normal concrete however at 6000 C copper slag concrete shows similar trends like normal concrete. In the present experimental study, M20 & M30 concrete grades were used.

Natural river sand is one of the important constituent materials in concrete production while stone dust is a material obtained from crusher plants which is also sometimes being used either partially or fully in replacement of natural river sand in concrete production. Use of stone dust in concrete not only improves the quality of concrete but also conserve the natural river sand. However, due its scarcity and environmental degradation caused resulting from excessive mining of Natural river sand, there is need to investigate an alternative material of the same quality which can replace river sand in concrete production. In the present study, experiments were carried out to study the gradation of aggregates, workability, compressive strength and split tensile strength of concrete made using quarry dust as replacement of fine aggregate at 0, 25, 50, 75, and 100%. Grade M15 of concrete was produced with ordinary Portland cement (OPC) for referral concrete while M25 of concrete was prepared for compressive strength and split tensile strength concrete. Workability and Compressive strength were determined at different replacement level of fine aggregate and optimum replacement level was determined based on compressive strength. Results showed that by replacing 50% of fine aggregate with quarry dust, concrete of maximum compressive strength can be produced as compared to all other replacement levels. The effect of quarry dust on compressive strength and split tensile strength was investigated and from the overall result obtained, it was observed that the compressive strength and split tensile strength increased significantly for all the curing ages from 0% to 50% replacement level of quarry dust. Maximum value obtained for 28day compressive and tensile strength were 25N/mm2 and 2.3N/mm2 respectively and this occurred at 50% replacement.

Concrete is the most widely used construction material today. The constituents of concrete are coarse aggregate, fine aggregate, coarse aggregate and water. Concrete plays a major role in the construction industry and a large quantum of concrete is being utilized. River sand, which isone of the constituent used in the production of conventional concrete, has become expensive and also a scarce material. In view of this,the utilization of demolished aggregate which isa waste material has been accepted as building material in many countries for the past three decades. The demand of natural sand in the construction industry has increased a lot resulting in the reduction of sources and an increase in price. Thus an increased need to identify a suitable alternative material from industrial waste in place of river sand, that is eco-friendly and inexpensive construction debris i.e fresh concrete being extensively used as an alternative to the sand in the production of concrete. There is an increase in need to find new alternative materials to replace river sand so that excess river erosion is prevented and high strength concrete is obtained at lower cost. One such material is building construction debris: a by-product obtained during construction and demolition waste. An experimental investigation is carried out on M 25 concrete containing debris during construction in the different range of 20%, 30% & 40% by weight of sand. Material was produced, tested and compared with conventional concrete in terms of workability and strength. These tests were carried out on standard cube of 150×150×150 mm and beam of 700×150×150 mm for 28 days to determine the mechanical properties of concrete.

The demand for natural aggregates (river sand) is increasing day by day, leading to the destruction of the environment, a burden that will be passed on to young people. Further, wastes from various industries are being dumped in landfills, which poses serious environmental problems. In order to ensure sustainability, both the issues mentioned above can be solved by utilizing industrial waste as aggregate replacement in the concrete construction industry. This research is done to find out the results using two substances viz., waste foundry sand (WFS) and coconut shell (CS) substitute for river sand and coarse aggregate. Many researchers have found the maximum benefits of substituted substances used in cement, which has material consistency. This current observation explores these strong waste properties of waste-infused concrete and cement, which experience shrinkage from drying out. The replacement levels for waste foundry sand were varied, between 10%, 20%, and 30%, and for CS, it was 10% and 20%. The experimental outcomes are evident for the strength, which increases by using WFS, whereas the strength decreases by increasing the CS level. The concrete that experiences shrinkage from drying out is included in the waste material, showing a higher magnitude of drying shrinkage than conventional concrete.
