project report on foundry sand use in concrete
Sand, rarer than one thinks
One way to estimate the global use of aggregates indirectly is through the production of cement for concrete (concrete is made with cement, water, sand and gravel). The production of cement is reported by 150 countries and reached billion tonnes in 2012 (USGS, 2013a).
STUDY OF LIGHTWEIGHT CONCRETE BEHAVIOUR
Aerated concrete does not contain coarse aggregate, and can be regarded as an aerated mortar. Typically, aerated concrete is made by introducing air or other gas into a cement slurry and fine sand. In commercial practice, the sand is replaced by pulverizedfuel ash or other siliceous material, and lime maybe used instead of cement [2].
