Abstract

Quality of construction, its ecological safety, durability of houses and constructions are common tasks for both suppliers and consumers of raw materials. One of the most important factors and a quality guarantee for concrete and iron–concrete constructions, both precast and solid ones, is the use of high–quality cement.

Great volumes of construction, fast pace of construction in Saint–Petersburg, Moscow and Moscow Region require terms of concrete curing in site–cast concrete buildings to be shortened, and cycles of steam–treatment in precast iron–concrete production to be decreased.

Therefore today the cements complying with requirements of European Standards ЕN–197, or with requirements of Russian State Standard (GOST) 31108–2003, harmonized with EN–197, are in the greatest demand.
