Abstract. Lightweight aggregate concrete mixtures incorporating 0, 10, 20, and 30 weight percent replacement of normal-weight aggregate with lightweight aggregate and crushed stone as fine aggregate were tested at 7, …
The influence of natural and crushed stone very fine sand (finer than 75 micron) on the performance of fresh and hardened concrete was investigated. The tests w.
Finally, the variation in the breaking stress of concrete made from crushed sand is 15.5 N/mm 2 at 7 days, 16.05 N/mm 2 at 14 days, and 18.05 N/mm 2 at 28 days. Conclusion: Congo River sand has ...
Hence the crushed sand will have greater water demand than that of natural sand resulting in slightly higher cement consumption. However, if crushed sand is properly graded with adequate fines the mix may have lower water demand when compared to poorly graded natural sand. Besides crushed sand can afford better control on gradation when ...

Crushed stone is available in a variety of colors and textures, depending on the quarry where it was sourced. Some common colors include white, gray, and red. Crushed stone can also be angular or rounded, depending on the shape of the stones that were used. The process of producing crushed stone typically involves several stages:
The density of crushed concrete can vary based on the origin and composition of the concrete being crushed. Generally, it ranges from approximately 2,100 kg/m³ to 2,500 kg/m³ (131 lbs/ft³ to 156 lbs/ft³).
