Experimental Study on Suitability of Sea Sand as Fine ...

2018-7-30  Within 7 days most of the strength is attained, but hardening takes another three weeks to reach design strength. The more cement added, and the harder the rock, the stronger the concrete becomes. Sand is needed (about one third) because the broken rock, does not fit neatly together again.

Development of High Strength Concrete using Artificial ...

2020-8-13  Current scenario of construction industry for development of concrete natural sand is commonly used as fine aggregate. Due to an infrastructure development, the natural sand resources depleting day by day. It is expected that fine aggregates suitable for use in concrete will become scarce and significant increase in its cost. Sand mining from our rivers becomes objectionable, also disturb nature of ecosystem of our country. Also, government had restricted quarrying of sand from natural resources, resulted in the need to identify new source of fine aggregate.

STUDY ON PERFORMANCE OF MANUFACTURED SAND

2016-12-31  Abstract—Paper presents the viability of manufactured sand as fine aggregates in high strength concrete (M60 Grade) construction. Due to rapid growth in industrial and infrastructural developments, necessitates huge demand of concrete for infrastructure development worldwide and extreme scarcity of natural sand availability. Investigation carried out by varying 0% to 100% replacement of natural sand using manufactured sand in high strength concrete mix with and without super plasticizer as an admixture. Current investigation revealed that M 60 Grade concrete using complete manufactured sand with super plasticizer yielded an excesses strength of 11.56%, 11.66% and14.85% compared to conventional concrete for 7 days, 14 days and 28 days respectively with increase in slump. And an increase in compressive strength of 16.19%, 10.97% and 12.46% compared to conventional concrete without using admixture and a reduction of slump is noticed. Investigation reveals that, 100% replacement of manufactured sand exceeds the target strength, but 70% replacement performs better in workability and strength
