As human societies grow, the problem of waste management becomes one of the pressing issues that need to be addressed. Recycling and reuse of waste are effective waste management measures that prevent pollution and conserve natural resources. In this study, the possibility of using glass waste as an alternative was used as a partial weight substitute for fine aggregates with replacement ratios of 10, 20, 30, and 40% by the weight, and formed into test models (15 cm * 15 cm ) cube and (15 cm * 30 cm) cylinder, then matured and tested their strength compression and tensile strength at the age of 7 and 28 days and compared with a reference or conventional concrete with a mixing ratio (1: 1.5: 3) as well as testing its workability on fresh concrete. The results showed the possibility of using crushed glass wastes in concrete as a good alternative to fine aggregates, up to 30%. The compressive strength and tensile strength results at this ratio were 92.6% and 80.86% at the age of 28 days, respectively.

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.

AbstractConcrete is the most widely used construction material in the world. Over ten billion tons of concrete are being produced each year resulting in exhaustion of natural materials and an enormous carbon footprint. One of the primary goals of concrete technology today is to reduce the use of Portland cement and natural fine aggregates by partially replacing them with various waste materials and by-products of industrial processes. The paper summarizes the results of a study where the partial replacement of river sand and Portland cement was successfully applied using steel slag aggregate, silica fume and glass waste.

Aim of this investigation was to study the effect of lathe scrap fibre and steel fibre replacement in concrete at different percentage so that we can achieve an improved and more durable concrete comparative to conventional concrete. Concrete is weak in tension and good in compression and also it is less ductile therefore, to terminate those weaknesses of concrete reinforcement bar is combine with it, but the reinforcement bar can’t fulfil the requirement of mechanical strength of concrete so to fulfil the requirements lathe scrap fibre and steel fibre is added so that the better composite material is achievable. After the investigation on several researcher work, we find 1.2% to 1.5% of lathe scrap fibre or steel fibre replacement according to weight of concrete, this is the optimum replacement in concrete to improve mechanical strength. But according to another research paper in which fine aggregate is partially replaced by lathe scrap fibre at percentage of 15%, 30% and 60% by its weight and it also improves the mechanical strength in compare to conventional concrete. Therefore, the review study characterize the utilisation of lathe scrap fibre and steel fibre in FRC improves the tensile strength and provides better resistance for early crack development in concrete. And also inexpensive, easily available and furthermore best for retrofitting and shotcrete techniques.

Concrete is the major composite material used in construction industry, it is strong in Compression and weak in tension and also has high self-weight. The light weight concrete was a alternative to conventional concrete due its low weight it decreases the self weight. Comparatively by using the light weight materials that occur either naturally or industrial waste, these material helps in reducing the cost and to improve the performance. Presently in India, more than 960 million tones of solid waste were being generated annually as by-products during industrial, agricultural mining and other processes. This paper deals with coconut shell concrete, which is one of the solid waste in the environment, and the use of this coconut shell as a replacement to coarse aggregate will reduce the weight of concrete by 25%. The other waste that was disposed mostly was sawdust. It was a byproduct of cutting or drilling of wood with saw or other tool. It is composed of fine particles of wood. It is having many advantages over traditional concrete like low bulk density, better heat preservation and heat insulation property. As said earlier to make concrete strong in tension coconut fiber is added, which is a waste material that left to disposal and as it is strong and stiff will hold the concrete material and also controls the crack. This study investigates on the use of sawdust as partial replacement for fine aggregates in concrete production. Sawdust was used to replace fine aggregates in Conventional and as well as in Coconut Shell concrete from 0%, 5%, 10% and 20%. M25 grade of concrete was selected and testing is evaluated at age of 3, 7 and 28 days. From the results, increase in percentage of saw-dust in concrete cubes led to corresponding reduction in compressive strength values, and the optimum saw-dust content was obtained at 5% in conventional as well as in coconut shell concrete , coconut fiber was added at the optimum value of sawdust on conventional and coconut shell concrete at 1%,2%,3%,4% and 5%. The better strength was obtained at 2% addition of fiber in coconut shell concrete and at 3% addition in conventional concrete.
