Факторы долговечности изделий на основе нефтебитуминозных пород и продуктов их переработки

Abstract

Aggressive factors acting on the structure of porous concrete, are alternately freezing and thawing, wetting and drying, carbonization of the material and its associated internal stresses in the products, the effect of a number of corrosive gases (hydrogen sulfide, sulfur dioxide, ammonia, carbon dioxide), and others. Cellular concrete, subject to certain design requirements and comply with a set of rules in the process of construction and operation, has sufficient durability.
