“…Furthermore, the formation of CSH due to pozzolanic reaction of waste glass and marble waste enhance the viscosity of concrete leading to less workable concrete. Similar results were reported by past researcher’s 22 , 40 . Although some of study show that workability concrete increased with incorporation of waste marble and waste glass due to filling voids in between concrete ingredients resulting less cement paste is required for lubrication 12 , 41 .…”

“…Therefore, workability is one of the prime factors that must be consider during mix design of concrete. According to past researcher’s, waste glass and marble waste decreased workability of concrete 22 . Therefore, 1.0% (4.25 kg) superplasticizer by weight of cement is kept constant throughout study.…”

“…Also, minor peaks of quartz and other chemical were also observed at different angle. It can notice that chemical composition of waste glass is more than 70% which show that, waste glass can be used as binding material (pozzolanic material) 22 .…”

“…Some studies show that, workability concrete reduced with addition of waste glass which enhance compaction efforts leading to porous concrete which adversely affect mechanical and durability aspects of concrete 20 . It has been suggested that filler materials could be added to waste glass concrete, which fills voids between ingredients of concrete, giving dense concrete 22 . Different materials can used as filler materials including stone dust, waste tiles, ceramic materials, waste foundry sand 23 .…”

“…Therefore, it is essential to add filler material (waste marble) in to waste glass concrete which fill voids between concrete ingredients, resulting more dense and durable concrete. A study concluded that waste marble can be successfully utilize as filler materials in concrete and further research was recommended that pozzolanic material must be added to obtain high strength durable concrete 22 . Therefore, in this research, waste glass was used as binding material (pozzolanic material) while waste marble was as filler material.…”

Industrial 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.

In developing countries, cement is one of the most consumed materials, which leads to a huge quantity of emission of carbon dioxide (CO 2 ) gas into the atmosphere. Cement could be replaced with materials that have pozzolanic properties and filler ability such as wheat straw ash (WSA). The focus of the present research is to substitute cement with WSA and fine aggregate with waste marble powder (WMP) in different doses ranging from 0% to 20% and 0% to 30% with 1.5% hooked end steel fibers in concrete. To evaluate different characteristics of concrete made with WSA, WMP and steel fibers, tests such as compressive, split tensile and flexural strength, sorptivity, water absorption and microstructural analysis were performed, From the lab results, it was revealed that the optimum dosage for concrete with improved properties was 15% WSA, 30% WMP, and 1.5% steel fibers. An improvement of 43.5%, 59%, and 45.96% was observed in compressive, split tensile, and flexural strength. Water absorption and sorptivity were reduced by 15.9% and 29% with the addition of WSA
