Effects of artificial lightweight aggregate on autogenous shrinkage of concrete
Factors influencing autogenous shrinkage of lightweight aggregate concrete, such as the type, moisture content, and unit quantity of artificial lightweight aggregate, have been studied experimentally. It was found that the autogenous shrinkage of concrete is reduced by using lightweight aggregate and that the autogenous shrinkage of lightweight aggregate concrete decreases with increasing moisture content and unit quantity of lightweight aggregate. These observations suggests that water lost internally by self-desiccation of cement paste is replaced by moisture from the lightweight aggregate.
