Abstract
Today concrete is one of the main building materials, used in the process of construction. Concrete mixtures must have high workability, retarding setting, quick hardening, long time transportation with further easy casting into molds, versatility of application and obtaining the constructions, not requiring significant expenses, connected with waterproofing works. At this it should not be forgotten that the main task is the provision of the required strength and durability of concrete construction that is the possibility of long time resistance to mechanical loads, chemical and physical environmental influences. Special interest is drawn to concrete protection from the influence of aggressive environments or in other words, to the increase of concrete sulfate resistance as it is exactly the sulfate water environment of different aggression levels is mostly often found in the ground waters. The influence of sea waters and sewage drains on the concrete constructions is similar to the influence of the sulfate water medium of different aggression levels. Water impact is one of the main factors influencing the durability of concrete constructions.
