ABSTRACT
Effect of curing conditions on short-term and long-term strength and deformation of gypsum-slag concrete, which is demoulded at early age and does not need any heat-wet treatment, is discussed. It is found that the strength may be greater in interior layers of products in spite of great moisture content. It is shown that the protection of small-size elements may be recommended against quick drying but not against moistening. The material long-term strength and durability prediction based on fracture mechanics seems to be valid. 1 Introduction
The well-known economical and technological advantages of gypsum-based products (high productivity, low production cost, unlimited raw materials) stipulate for wider gypsum-containing material application in construction. However, low water resi stance and "catastrophical" gypsum creep on moistening, especially, limit the possi bility of its usage in loaded structures.
