“…Gained higher strength at 60% by substituting the river sand by M sand at various proportions such as 0%, 20%, 40%, 60% and 80% [14]. The concrete flexural strength increased up to 2% and 4.3% by 25% and 100% incorporation of river sand by M sand [15]. Compared to the air curing and standard moist curing, the membrane curing will give the good strength in both river sand and M sand.…”

This, research work was to study the potential of M-sand as compared to river sand in concrete, here M-sand is replaced by river sand 0%,45%,50%,55% and 100% in the concrete mix, Mix design is designed as per IS Standards. In this research a mix 1:2.32:2.82 (M20) was considered. The test specimen was casted for 7days, 28 days and 90days. The performance of M-sand was determined by several experiments such as slump test, impact strength test, flexural Strength, and compressive strength test. The results attained from each test states that as M-sand increases the slump value decreases. flexural strength, compressive strength and impact test of concrete at 7 days, 28 days and 90 days is greater at 100% and 50% replacement of M sand by river sand.

“…Regression analysis was carried out and the empirical formulas were used to obtain the quarry dust concrete. It was also noted that the flexural strength of concrete is enhanced when quarry dust is incorporated [7]. In the present research work, the mechanical and durability properties of concrete specimens with and without fly ash and micro silica addition were experimentally assessed.…”

Concrete incorporates large amount of natural resource as aggregates with cement and water. Cement production consumes huge energy and causes about 7% of total greenhouse gas emission in the world. It has been strived to provide better quality in concrete using waste by-products from industries so that natural resources are used in an efficient manner and thereby the environment is protected from waste deposits. Hence, mineral admixtures like fly ash and micro silica can be used to overcome these issues. The demand for river sand is getting increased day by day, which affects its constant supply. Under these circumstances use of quarry dust becomes inevitable. The usage of fly ash in the concrete leads to strength gain only at later stages. In order to obtain strength during the early stage, micro silica is added as a partial replacement of cement. The properties of fly ash, micro silica and quarry dust were studied. Fly ash (0-40%) and micro silica (0-15%) are used as a partial replacement for cement and quarry dust (50%) as that for river sand by mass. Mechanical properties of the concrete containing hybrid mineral admixtures and quarry dust are studied systematically.

“…Overall, their results revealed that with the raise of M-sand as a substitution in place of river sand, the compression strength of concrete rises. It has been explained that tremendous bonding between fine and coarse aggregates is the main reason for the compression strength increment of concrete with M-sand [5,6], [7].…”

“…Concrete mix with replacement level of 0%, 25% and 100% manufacture sand and tested at the age of 28-days and the maximum modulus of rupture obtained is when the sand is 100% replaced by the M-sand. It was found that the modulus of rupture increase as the compression strength of the concrete increase [7].…”

The impact of Manufacture sand on UPV, compression strength and modulus of rupture has been experimentally investigated and discussed in this paper. Concrete grade 30 (30Mpa) were produced with different percentage of M sand substitution ranging from 25%, 50%, 75% and 100% by volume were selected as concrete mix design in this project. The strength for different percentage of M-sand incorporation was measured by the destructive test which are compression strength test and modulus of rupture test and nondestructive test which is UPV test for curing ages of 90, 28 and 7 days. Furthermore, the highest compression strength of concrete and modulus of rupture was found on the 90th day containing a proportion of 75% of M-sand as a substitution for natural fine aggregate. A novel empirical equations 1 & 4 are proposed for the relation of compression strength with the modulus of rupture and UPV.
