Natural (River) Sand: The natural sand having fineness modulus of 2.9 and conforming to zone II as per IS: 383-1970 [5] was used for the experimentation after washing it with clean water.The specific gravity of this natural sand was found to be 2.7.
2.3 Experimental Result and Discussion. Table 3 summarizes the test results of the studied concrete. The slump of concrete increased greatly as the fine artificial sand was blended, the highest slump was 3.5 cm at W F = 5%. The highest compressive strength was at W F = 10%, regardless of testing age. The blending fine artificial sand with …
Artificial sand can be obtained by mixing washed sand formed from the the poor quality of natural sand with high clay content and stone powder formed from processing and screening production by appropriate ratio, Which be applied to C20~C35 ready-mixed concrete. By studying the effect the artificial sand on the properties of fresh concrete …
artificial sand was found to be 1.856 g/cc. The average void ratio of natural sand and artificial sand was found to be 0.344 and 0.288 respectively. Bulking of artificial sand was higher than natural sand for same percentage of water added. At 8 per cent water content in natural sand and artificial sand, maximum bulking was occurred.
