AbstractIndustrial waste has been rapidly increased day by day because of the fast-growing population which results environmental pollutions. It has been recommended that the disposal of industrial waste would be greatly reduced if it could be incorporated in concrete production. In cement concrete technology, there are many possibilities to use waste materials either as cement replacement or aggregate in concrete production. Two major industrials waste are glass and marble waste. The basic objective of this investigation is to examine the characteristics of concrete waste glass (WG) as binding material in proportions 10%, 20% and 30% by weight of cement. Furthermore, to obtain high strength concrete, waste marble in proportion of 40%, 50% and 60% by weight cement as fine aggregate were used as a filler material to fill the voids between concrete ingredients. Fresh properties were evaluated through slump cone test while mechanical performance was evaluated through compressive strength and split tensile strength which were performed after 7 days, 28 days and 56 days curing. Results show that, workability of concrete decreased with incorporation of waste glass and marble waste. Furthermore, mechanical performance improved considerably up 20% and 50% substitution of waste glass and waste marble respectively. Statistical approach of Response Surface Methodology (RSM) was used optimize both waste materials in concrete. Results indicate better agreement between statistical and experimental results.

A responsible approach towards sustainable development requires the use of environmentally friendly, low-carbon, and energy-intensive materials. One positive way is to use glass waste as a replacement for fine natural aggregate. For this purpose, the effects of adding glass cullet to the mechanical properties of mortar were carried out. The glass aggregate made from recycled post-consumer waste glass (food, medicine, and cosmetics packaging, including mostly bottles), were used. This experimental work included four different contents of fine glass cullet (5, 10, 15, and 20 wt.% of fine aggregate). The compressive, flexural, and split tensile strengths were evaluated. Moreover, the modulus of elasticity and Poisson coefficient were determined. The addition of glass sand aggregate increases the mechanical properties of mortar. When comparing the strength, the obtained improvement in split tensile strength was the least affected. The obtained effect for the increased analysed properties of the glass sand aggregate content has been rarely reported. Moreover, it was determined that by increasing the recycled glass sand aggregate content, the density of mortar decreased. In addition, the relationships between the properties for mortar containing glass sand aggregate were observed.

The Matrix

Slurry infiltrated fibrous concrete (SIFCON) is a new and unique type of high performance concrete invented by Lankard in 1979, containing high percentage of fiber about 6% to 20% by volume. SIFCON possesses high strength as well as large ductility and has excellent potential for structural application. The matrix in SIFCON has no coarse aggregate but high cementitious content. The aim of study is to evaluate the performance of SIFCON mortar with lower fiber percentage and to minimize the fine aggregate usage by replacing it with industrial waste i.e. steel slag. Thereby, it also helps in effective disposal of industrial waste and helps in mitigating environmental pollution. The main objective of this study is to determine the effect of partial replacement of sand with steel slag on the mechanical properties of SIFCON mortar. The experimental program was carried out with 2%, 3% and 4% of fiber content by volume combined with replacement of sand by steel slag in proportion of 10% and 20% by weight. For this purpose, compressive strength, flexural strength, split tension and impact strength of SIFCON specimens were tested after 7 and 28 days of curing, yielding positive results.

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.

The proposed study present behaviour of concrete with inclusion of waste foundry sand (WFS), waste glass, and glass fiber in different concrete trial mixes. Waste foundry sand (WFS) is basically by-product formed from metal casting industries ferrous or non-ferrous, which due to rapid concrete construction in world used as an alternative of sand. Waste glass can be used in concrete in crushed form as a replacement of aggregate or in powdered form as a replacement of cement, the only problem with waste glass is it is prone to alkali-silica reaction due to different composition of different types of glasses. Glass fiber is added with waste glass and waste foundry sand (WFS) to increase strength. Normal concrete grade M25 (1:1:2) is used for this experimental purpose, different concrete trials were casted which consist of replacement of sand with waste foundry sand in different proportion (0%, 10%, 20%, and 30%). Next trial consists of optimum value of (WFS) with different proportion of waste glass (0%, 10%, and 20%, 30%) as a replacement of fine aggregate. Final trial consists of addition of glass fiber (0%, 0.25%, 0.50%, and 0.75%) in optimum value of second trial. Mechanical properties of concrete compressive strength, split-tensile strength, flexural strength was examined at 7, 14, 28, and 56 days curing period.

The mechanical and durability properties were best at 45% GGBS and 5% Waste Glass with 0.4 water/cement ratio. The recycled materials implemented for mix proportion were waste glass provided considerably to enhance its properties when added with GGBS. In most of the research work, the effect of WG and GGBS in concrete as a partial substitution of fine aggregate and cement individually is analyzed. Previous studies only show the individual impact of these concrete recycled materials on mechanical and durability properties. In the present study, an exact optimum substitution level of cement by GGBS (15 – 60% at an increment of 15%) and fine aggregate by the waste glass (5 – 20% at an increase of 5%) combined for OPC concrete mix. Mechanical (compressive strength, split tensile strength and flexural strength) and microstructural properties (FESEM) were observed on the combination of waste glass and GGBS concrete mix.

Reusing of waste glass in concrete production is among the attractive option of achieving waste reduction and preserving the natural resources from further depletion thereby protecting the environment and achieving sustainability. This present study examines the possible reuse of waste glass crushed into fine and coarse aggregate sizes as partial substitute for natural fine and coarse aggregate in concrete. The variables in this study is both the fine and coarse aggregate while the cement and water-cement ratio were held constant. The crushed glass was varied from 0 – 100% in steps of 25% by weight to replace the both the natural fine and coarse aggregate in the same concrete mix. Concrete mixes were prepared using a mix proportion of 1:2:4 (cement: fine aggregate: coarse aggregate) at water-cement ratio of 0.5 targeting a design strength of 20 MPa. Tests were carried out on total number of 90 concrete cube specimens of size 150 x 150 x150 mm and 90concrete cylinder specimens of dimension 100 mm diameter by 200 mm height after 3, 7, 14, 28, 42 and 90 days of curing. Test results indicated that the compressive and split tensile strength of the hardened concrete decreases with increasing waste glass content compared with the control. However, concrete mix made with 25% waste glass content compared significantly well with the control and can be suitably adopted for production of light weight concrete.

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.

Abstract Self compacting concrete (SSC) is also brittle nature, resulting in abrupt failure without giving any warning, which is unacceptable for any construction materials. Therefore, SCC requires tensile reinforcement to increase tensile capacity and avoid the undesirable brittle failure of SCC. However, fiber improved tensile capacity more efficiently than compressive strength. Therefore, it important add pozzolanic material to fiber reinforced concrete to obtain high strength, durable and ductile concrete. This research is carried out to evaluate the qualities of concrete with addition of waste marble and coconut fiber in concrete. Marble waste used as binding (pozzolanic) materials in proportion of 5.0 to 30% by weight of cement in increment of 5.0% and concrete is reinforced with coconut fiber in proportion of 0.5% to 3.0% by weight of cement in increment of 0.5 %. Rheological properties were assessed through its passing ability and flowability by using Slump flow, Slump T50, L-Box, and V-funnel tests while mechanical performance were evaluated through compressive, split tensile, flexure and pull out tests. Tests results indicate that marble waste and coconut fiber decrease the passing ability and filling ability of SCC. Furthermore, tests results indicate that marble waste up to 20% and coconut fiber addition 2.0% by weight of cement have a tendency to enhance the mechanical strength of SCC. Finally, Statistical analysis (RSM) was used to optimize the combined substitution of marble waste and coconut fiber to obtain high strength concrete.
