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.

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.

Nowadays, there is a considerable shortage in the availability of river sand and natural stone aggregate for the construction activities all around the globe and the way out is being worked out by the use of discarded foundry sand and crushed brick masonry aggregate for construction purposes. In the present study, river sand was partly replaced by the discarded foundry sand procured from steel moulding industries and the crushed brick masonry aggregate was used as coarse aggregate for the production of lightweight concrete. The experimental program involved casting of six distinct mixes with 0%, 20%, 40%, 60%, 80% & 100% replacement of fine aggregate by discarded foundry sand. The mechanical and durability properties of the lightweight concrete were assessed for each of the six diverse blends. Even though the 80% and 100% replacement mixes were found to be less dense than the rest of the mix, the blend of 40% replacement acquired desirable mechanical and durability properties when compared to that of all other mixes. The optimum replacement level of the discarded foundry sand by mass to the river sand was 40%. The lightweight concrete produced by utilizing crushed brick masonry aggregate and discarded foundry sand (40% substitution level) can be employed in all major structural lightweight construction aspects and is ideally suited for sloped roof slabs and making architectural or decorative concrete blocks.

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.

Study Results

Increasing human awareness of the importance of protecting the environment and conserving natural resources requires concrete innovation as an environmentally friendly and sustainable material. Accumulated of solid waste begins to be processed and reused, one of which is as a constituent of concrete. Among the various types of solid waste, glass waste is considered as an alternative that can be used as a substitute for fine aggregate (sand), coarse aggregate (split stone) and cement. This study investigated the use of mix coloured glass waste consisting of clear, green, and brown as partial substitution of sand in concrete. Although the glass colors were mixed, the proportion of each color had been determined in this study, namely 25%, 25%, and 50%. The purpose of determining these proportions is to find out which type of color glass has the most effect on concrete mix. The target characteristic strength of 25 MPa was produced by replacing sand with 20% of mix coloured waste glass. Three combinations of concrete mixes were prepared for this study. Compression tests were conducted at 7, 14, and 28 days. Workability of fresh concrete, density, compressive strength, and failure mode were investigated in this study. Results showed that the use of waste glass was able to increase the workability of fresh concrete. K1, K 2, and K3 obtained slump values which were 4%, 6,7%, and 1,3% higher than normal concrete. Normal concrete and all combinations exhibited similar density values. Only normal concrete achieved the characteristic strength of 25,7 MPa at 28 days. Meanwhile K1, K2, and K3 achieved strengths of 22,4 MPa, 22,1 MPa, and 24,7 MPa, respectively. It was evident that as workability values increased, the compressive strengths were noticed to reduce.

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.

In this study, the effectiveness of waste Polyethylene Terephthalate (PET) fibers in improving the properties of concrete was investigated. Recycling of waste PET bottles is a daunting task in developing countries due to inadequate recycling facilities. The main aim of this research paper is to investigate the mechanical behavior of the components by using PET fibers. This paper describes the performance of PET fiber reinforced concrete for two grades of concrete mix M20 and M30. An experimental work has been carried out on the specimens like cubes, cylinders and beams which were casted in the laboratory and their behavior under the test was observed. The PET fibers were replaced to the fine aggregate volume from 0.0% to 2.0%. The compressive strength, split tensile strength and flexural strength of concrete were determined after 28 days of curing period. The highest compressive, split tensile and flexural strength of concrete was observed at 1.5% fiber volume replacement to the fine aggregate. The study concludes that the replacement of waste PET fibers to fine aggregate in concrete serves as a means of utilizing the waste generated by PET bottles to increase the strength of concrete.

The Cost

Sand is the most normally utilized fine aggregate in construction industry for the generation of concrete. The present scenario is in such a way that the cost of sand reached new heights and the demand for sand is also exhaustive. The replacement of the sand has a lot of constraints. Seashells are composed of calcium carbonate or chitin can be suitable alternative. It is used as a replacement of fine aggregate by 2%, 4%, 6%, 8%, and 10% for M20 grade concrete. Further 15% and 20% replacements are made. Silica fume is a ultrafine powder gathered as a result of silicon and ferrosilicon compound generation and the principle field of use is as pozzolanic material. It is used as an admixture by 5% to 10% of weight of cement to improve the strength properties. Concrete cubes and cylinders with mentioned proportion and conventional concrete are casted. Mechanical properties are evaluated by conducting compressive strength and split tensile strength tests.
