“…The results finally reveal the influence on the UHPC flexural strength due to WFS replacement up to 15%, but a only slight effect up to 10%. Once more, my results can be supported by the results published by other researchers on low-, normal-and high-strength concrete [3,4,[8][9][10][11][12][13][14][15][16], in which WFS has an effect on the density and workability that results in an impact on the flexural strength values.…”

“…Notwithstanding, there was no significance between the 0% and 15% WFS, which is an advantageous result as it reveals that WFS has no effect on the splitting tensile strength at 15% substitution; this can increase UHPC durability without compromising splitting tensile strength. Similar to the results of the compressive strength, the impact of WFS on reducing the density and workability of low-, normal-and high-strength concrete had much the same influence on the splitting tensile strength [3,4,[8][9][10][11][12][13][14][15][16]. .4% compared to the reference mixture.…”

“…In previous research, high contents of cement, fine natural sand and silica fume were mostly used to prepare UHPC [29,37]. It was found that the most successful fine aggregate replacements with WFS in conventional concrete were predominantly below 30% [2,8,11,14].…”

“…When the WFS was added to the mixtures, decreases in the slump values and unit weights were observed with an increasing amount of WFS. Prabhu et al [11] discovered that an augmentation in WFS content up to 10% reduced the slump of normal strength concrete, and then remained constant for dosages up to 50% WFS. Note: CWFS0 = control concrete; CWFSa = concrete with WFS, where a = waste foundry sand content (in %).…”

“…The finest sand fractions cannot be reused and constitute waste mass directed to landfills, the main component of WFS. Studies have shown that is possible to utilize WFS in high-strength, normal and low-strength concrete and WFS can positively impact their mechanical properties [2][3][4][8][9][10][11][12][13][14][15][16].…”

Waste foundry sand (WFS) is a ferrous and non-ferrous foundry industry by-product, produced in the amount of approximately 700 thousand tons annually in Poland and it is estimated that only a small percentage of this waste is recycled. The study used WFS to produce ultra-high performance concrete (UHPC) as a partial substitute for quartz sand. It was replaced with WFS levels of 0%, 5%, 10%, and 15% by weight of quartz sand content. The UHPC mixtures were produced and tested to determine the compressive strength, flexural strength, splitting tensile strength as well as the modulus of elasticity at 28, 56, and 112 days. Scanning electron microscope (SEM) analysis was done to identify the presence of various compounds and micro-cracks in UHPC with WFS. The results revealed an increase as well as an insignificant decrease in the mechanical properties up to 5% and 10% WFS replacement, respectively. These studies also prove improvement in the microstructure of UHPC up to a 5% WFS level. In all the tested properties in this work, 5% WFS was found to be an apt substitute for quartz sand.

Industrial waste has rapidly increased day by day due to the fast‐growing population and usage of products, which dumps unscrupulously, resulting in environmental pollutions. Waste foundry sand (WFS) is one of the industrial solid wastes. River sand is generally used in concrete as a fine aggregate, which is limited (scant), and river excavation for sand leads to environmental deterioration. To resolve these problems, a study was performed on WFS as a partial substitution instead of natural sand in concrete. The effects of WFS on concrete performance were assessed through durability and mechanical performance. The results from experimental tests show that, compared to concrete blends with WFS up to 30% substitution, the control mix strength was only 7.6% (28 days) higher, and this improvement is not too high. In the same manner, concrete mixtures that contain WFS up to 30%, and their durability properties were somewhat same to blank max (control). Test results showed that WFS with a substitutions ratio up to 30% can be successfully used in concrete without disturbing its durability and strength properties.

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
