Meanwhile, for concrete made with 50 and 75% of coarse aggregate replaced with polystyrene gives an average of compressive strength of 9.2 and 4.7 N/mm 2 respectively. The result showed a huge difference in terms of compressive strength when the samples were compared to the control (M20 mix concrete).

Y. Guney et al. [4] investigate the potential reuse of waste foundry sand in high-strength concrete production. The natural fine sand is replaced with foundry sand (5, 10 and 15% by mass) to achieve a high-strength concrete of about 65 MPa, gaining that value at 56 days of curing with 10% waste foundry sand replacement: this is the optimum …

Manufactured sand (M-Sand) is artificial sand produced from crushing hard stones into small sand-sized angular shaped particles, washed and finely graded to be used as construction aggregate. It is an alternative to River Sand used for construction purposes. It is produced from hard granite stone by crushing.

A 45 N drop weight was used as the impact load. The number of strikes needed to cause the initial and ultimate failure of concrete samples by dropping a hammer from a height of 457 mm was noted. For the traditional sand concrete, made sand concrete and the best replacement of concrete, tests were carried out and results were presented. IV.

M sand achieves better bond with cement than the round particles of natural sand. This is due to the reason that artificial sand contains sharp edged particles. Some studies prove that concrete made using M sand has 6% to 9% higher compressive strength and 12% to 15% higher flexural strength than river sand material of the same …

An ever-growing population and a continuing trend towards urbanisation mean that around 40 billion tonnes of sand are mined each year to meet the world's increasing demand for construction materials. Because sand from the desert is unsuitable as a building material, it must be mined or dredged from rivers, deltas, and coastal and …
