COMPLEX TESTING OF AERATED CONCRETE

Abstract

The mechanic, thermomechanic, deflection and moisture properties of aerated concrete wall elements (GM 500/2) that have been in production since 1986 were investigated. The main causes of cracks appearing shortly after construction were: the inhomogeneous strength and modulus of elasticity depending on moisture distribution, the inhomogeneous and not "custom designed" other structural elements (slabs, beams), the very high strength of the applied mortar and inaccuracy in the attachment of element rows.
