Since it takes only a small amount of reactive aggregate to cause deterioration of concrete due to the alkali-silicate reaction, vast deposits of aggregates throughout the world are in danger of being rejected as undesirable for use in concrete unles

Coarse aggregate has a large influence on drying shrinkage which is one of the major causes of cracking in concrete structures. The stiffer an aggregate, the lower is the drying shinkage of concrete. Since it is not possible to alter the stiffness ch
