Concrete Sand. For the concreting purpose, we generally use coarse sand. The finest modulus of this sand should be 2.5 to 3.5 and it should not contain more than 4% silt. Classification of sand Fine Sand The sand passing through a sieve with an opening of 1.5875 mm is called as the fine sand. Fine sand is mainly used for plastering works ... Mar 01, 2017 Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch)Get Price

Asphalt Concrete is known by many differ-ent names hot mix asphalt, plant mix, bituminous mix, bituminous concrete, and many others. It is a combination of two primary ingredients - aggregates and asphalt cement. The aggr egates total 90 to 95 per cent of the total mixture by weight. They are mixed with 5 to 10 percent asphalt cement to form Feb 07, 2021 Image Loader. A loader is a heavy equipment machine used in construction to move aside or load materials such as asphalt, demolition debris, dirt, snow, feed, gravel, logs, raw minerals, recycled material, rock, sand, woodchips, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car).Get Price
Sand Washing Plants. McLanahan Sand Washing Plants process sand from its raw state into products that meet various specifications. The process requirements vary depending on the input and desired output, but plants typically scrub, liberate, deslime, wash, classify, decontaminate and dewater the sand, as well as process the effluent stream that results. It is reported that, for traditional screeds a mix proportion of 16 Portland cement sand/aggregate is a normal range that is commonly used. However, mix proportions of 14 cement to sand is widely applied which comply with British Standard (BS12). Mix ratio should produce a plastic, easy-working, cohesive mortar of plastering consistence.Get Price
