“…By replacing FeCr slag (10%, 20%, 30%, 40% & 50%) with river sand. Experimental results of splitting tension showed a decreased in percentage difference of 1.96%, 6%, 0.55%, 5.42% and 13.33%respectively than 100% of river sand strength (3,5) . Author studied by substituting FeCr (10%, 20%, 30% & 40%) with weight of river sand.…”

“…Flexural study by replacing FeCrslag (10%, 20%, 30%, 40% & 50%) instead of river sand. Although, there is a decrease in the percentage difference by 3.05%, 6.20%, 12.08, 8.52% and 10.16% respectively while comparing the control flexural strength (3) FeCr slag (10%, 20%, 30% & 40%) as fine aggregate in concrete instead of river sand was conducted. Flexural strength in comparison with control mix increases the percentage difference 0.03%, 1.48%, 3.48% and 5.22% respectively (4) .From Figure 4 the flexural strength of FeCr slag and Msand replacement are represented.…”

“…Chloride ion penetration is very low in 10% replacement of FeCr slag in concrete, but 20% to 50% replacement ranges from 1000 to 2000 coulombs respectively at 28 and 91 days. Mechanical strengths are increased up to 30% replacement of FeCr slag instead of virgin sand (3) . Hexavalent chromium and Total chromium cause skin ulceration, lung diseases and other health problems, if it exceeds the limit of USEPA 1992.…”

“…Hence, it implies that there is 30% to 40% of supplant FeCr slag in concrete matrix, which is suitable as traditional sand (4) . FeCr slag, which has a Chromium immobilization phase in concrete cluster is supplanted instead of river sand (5) . Crushing, splitting and flexural results of three various curing like water, acid and base are tested on7 days and 28 days,thereby strengthening 40% replacement of FeCr slag in concrete (6,7) .…”

Background/Objective: To review on the river sand supplants particularly Manufactured sand (Msand) and Ferrochrome slag (FeCr slag) aggregate in concrete and mortar matrix. Methods: A study on FeCr slag as sand is skimpy and countable; so here they clustered together and discussed for its performance..Msand by its shape, texture, physiochemical characters, strength parameters and durability is much similar to river sand in a concrete matrix. FeCr slag shape and texture is almost similar but porous in nature and ingredients like MgO and Cr 2 O 3 can cause an effect on concrete. Msand based on various grades and mechanical strength is analysed. Findings: Msand strength behaviour is discussed in detail with reference to other authors which clearly states that Msand is ideal for fine aggregate replacement. Industrial waste FeCr slag is replaced instead of sand, which also behaves well until 40% to 50% replacement of sand at later ages of strength. Compressive strength, splitting tensile strength and flexural strength of these two materials are graphically depicted from a literature surveys of recent researches. Novelty: This study provides robust information about strength performance of Msand and FeCr slag with varying percentage ranges from 10% to 60% by weight.
