Annotation: The influence of dry or water-saturated lightweight aggregate as well as extra mixing water on the properties of structural lightweight aggregate concrete mixtures and concretes - workability, slump loss, relative humidity change, autogenous shrinkage, degree of cement hydration and compressive strength have been investigated. The formulations of structural lightweight aggregate concretes with compressive strength of 54-56 MPa on the base of internal curing conception to reduce the risk of cracking due to the autogenous shrinkage have been developed.
Keywords: structural lightweight concrete, internal care, autogenic shrinkage, cracking.
Pages: 7-16.
