5 Aggregate Specifications and Requirements

Fine Aggregates All fine aggregates, except air-cooled blast furnace slag sand or granulated blast furnace slag sand, must have an acid insoluble content of not less than 40 percent. When using these slag sands, the acid insoluble content must not be less than 25 percent. The acid insoluble content is determined by ITM 202.

Physiochemical characterization of coarse aggregates in ...

Based on the results of the physiochemical characterization of coarse aggregates, imported gabbro was found to meet all the physical, mechanical and chemical limits of QCS (2010). Hence, it comes as no surprise that imported gabbro is the main source of coarse aggregates in Qatar, prevalently used in the construction industry.

Clay, Aggregate and Concrete

tivity and amount are reflected in the sand equivalent value hut not in the loss by decantation. Clay contami­ nants in concrete aggregate affect concrete properties primarily through their effect on water demand. Con­ crete strength and shrinkage correlate to a high degree with sand equivalent value and to a slightly lesser degree
