Handling and Storage. Concrete aggregates are a mixture of rocks and minerals. A mineral is a naturally occurring solid substance with an orderly internal structure and a chemical composition that ranges within narrow limits. These specifications limit the permissible amounts of deleterious Aggregates for Concrete Alkali-Aggregate Reactivity. Beneficiation. Handling and Storage. Concrete aggregates are a mixture of rocks and minerals. A mineral is a naturally occurring solid substance with an orderly internal structure and a chemical composition that ranges within narrow limits. These specifications limit the permissible amounts of deleterious Evaluation of Alkali-Silica Reactivity Using Aggregate and among them, a maximum permissible expansion of 0.10% at 2 weeks is the most standard citation (Tauma, Fowler Carrasquillo, 2001). Several researchers (Grattan-Bellew, 1990; DeMerchant Soles, 1993) also suggested different expansion limits in detecting aggregate reactivity for varying aggregate mineralogy, namely, Aggregates for Concrete shows these limits for fine aggregate and for one size of coarse aggregate.
