AbstractSeveral attempts upon inclusion of industrial waste materials such as fly ash, silica fume, GGBS, metakaolin and copper slag in concrete have already been experimented that exerted a significant impact on concrete with enhanced mechanical and improved durability properties. There were numerous authentic researches that reported the significance of steel fibers in strengthening the flexural property of concrete. The paper investigates the combined effect of waste glass powder (WGP) that has been utilized as a substitution for fine aggregate in varying percentages of 0%, 3%, 6%, 9%, 12% and 15% and further reinforcing it with recycled steel fibers (RSF), drawn from waste tires by volume of concrete. WGP was used as 0%, 3%, 6%, 9%, 12%, 15% by mass replacement of fine aggregate with four different volume fractions of recycled steel fiber (i.e., 0, 0.5, 1 and 1.5%), respectively. All proportions of concrete mixes were investigated to study the variations in compressive, flexural and split tensile strength with varied replacements levels of WGP along with various fractions of RSF for 7 and 28 days curing. A mix of 9% WGP exhibited the maximum compressive, flexural and split tensile strength. It was found that mechanical properties of concrete rose up to 9% replacement level of WGP and later declined. Also it was confirmed that increase in the amount of RSF further boosted the compressive and flexural behavior of concrete. Overall, an optimum concrete mix with 9% replacement of WGP, reinforced with 1% inclusion of RSF, reported the best performance compared to other mixes.

The Impact

The flexural behavior of Incinerated Bio-Medical Waste Ash (IBWA) – Ground Granulated Blast Furnace Slag (GGBS) based Reinforced Geopolymer Concrete (RGPC) beams with Waste Glass Powder (WGP) as fine aggregate is explored in this research. The fine aggregate (M-Sand) is substituted by varying the waste glass powder as 0 percent, 5 percent, 10 percent, 15 percent, 20 percent, 25 percent, 30 percent, 35 percent, 40 percent, 45 percent, and 50 percent, and the mixture is cured under atmospheric curing. The impact of the WGP weight percentage on the flexural behavior of GPC beams is analyzed. The conduct of RGPC beams varies from that of ordinary Portland Concrete (OPC) beams, which is defined and examined. Deflection, ductility factor, flexural strength, and toughness index were measured as flexural properties for beams. In contrast to the reference beams, the RGPC beams containing 50% Waste Glass Powder as fine aggregate demonstrated a major increase in cracking resistance, serviceability, and ductility, according to the experimental finding. The RGPC beam without WGP ended in failure with a brittle manner whereas those beams with WGP encountered ductile failure. The RGPC beams' load ability improved by up to 50% as the weight percentage of WGP was enhanced.

This paper for the first time investigates the workability, compressive and tensile strength of concrete containing Fly Ash, Rice Husk Ash and Waste Glass Powder. Seventy six cube specimen (150  150  150 mm were cast with different composition of Fly Ash, Rice Husk Ash ,Waste Glass Powder and steel fibers. The cubes were tested for axial compression and tensile tests. The research also investigated the effect of curing regime on the compressive and tensile strength of concrete cube specimen. The results revealed that the addition of 15 % Rice Husk Ash and 39% Fly Ash increased the workability of 25 % as compared to the controlled concrete. The sample containing 10 % Rice Husk Ash, 10% Waste Glass Powder and 39% micro silica produced worst workability as it decreased the workability up to 5 % of controlled concrete. The results for axial compressive strength shows that the addition of 15% Rice Husk Ash (RHA) and 39% of Fly Ash (FA) in concrete leads to the improvement of compressive strength by 14%. The sample containing replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP) and 39 % of micro silica (MS) in concrete leads to the improvement by 53.9 for compressive. The replacement  of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP ), 39 % of micro silica (MS) 3% steel fiber in concrete leads to the improvement by 37% for compressive strength. It was observed from the results of tensile strength that the samples containing 15% Rice Husk Ash (RHA) and 39 % of Fly Ash (FA) increased the tensile strength by 24% as compared to the controlled concrete. The sample containing replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP) and 39 % of micro silica (MS) in concrete leads to an increase of 20% as compared to the controlled ones. Also, the replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP), 39 % of micro silica (MS) 3% steel fiber increased the tensile strength by 40 % as compared to the controlled concrete sample. Finally, it was concluded that the replacement of 10% RHA, 39% micro Silica, 10% WG in concrete was found to be superior for increasing the mechanical properties of concrete.

Strength And Durability

The goal for taking p this exploration is because of the at that now a days the natural sand affirming to Indian standards is becoming scarcer and costlier because of nonaccessibility in time for the reason that law of land, unlawful digging by sand mafia etc… For this reason a motivation has been done to identify a new source of aggregates. The objective of this study is to verify the appropriateness, feasibility &forthcoming utilization of Stone powder for future years. Stone powder is a loss from the quarry preparing units. It accounts 30% of the residue from the quarry industry. Use of stone powder as a replacement of Natural sand reduces cost of construction but also it helps to reduce the wastage of material so it can be give a good impact to the environment. Hence in the current study an attempt has been made on concrete mix of grade M40 by experimenting the strength properties & durability of concrete by replacing Stone powder by 25%, 50%, 75% & 100% to Natural sand and expand the project the addition of steel fibers of 0.5%,0.75% and 1% have done and also the effect of curing of 3% of H2SO4 , HCI and Sea water on these concrete mixes are determined by immersing these cubes for 28 days, 90 days in above solutions and respective changes in compressive strength, tensile strength & weight reduction observed and it has been found that the compressive, split tensile strength of concrete made of stone powder increases nearly 17% and 60% with addition of steel fibers. The durability studies show a decrease of nearly 17% in compressive strength

This study aims to provide a thermophysical characterization of a new economical and green mortar. This material is characterized by partially replacing the cement with recycled soda lime glass. The cement was partially substituted (10, 20, 30, 40, 50 and 60% in weight) by glass powder with a water/cement ratio of 0.4. The glass powder and four of the seven samples were analyzed using a scanning electron microscope (SEM). The thermophysical properties, such as thermal conductivity and volumetric specific heat, were experimentally measured in both dry and wet (water saturated) states. These properties were determined as a function of the glass powder percentage by using a CT-Meter at different temperatures (20 °C, 30 °C, 40 °C and 50 °C) in a temperature-controlled box. The results show that the thermophysical parameters decreased linearly when 60% glass powder was added to cement mortar: 37% for thermal conductivity, 18% for volumetric specific heat and 22% for thermal diffusivity. The density of the mortar also decreased by about 11% in dry state and 5% in wet state. The use of waste glass powder as a cement replacement affects the thermophysical properties of cement mortar due to its porosity as compared with the control mortar. The results indicate that thermal conductivity and volumetric specific heat increases with temperature increase and/or the substitution rate decrease. Therefore, the addition of waste glass powder can significantly affect the thermophysical properties of ordinary cement mortar.
