Before the construction of any type of housing or, for example, before pouring its base, it is extremely important to acquire the most suitable cement for this work, because it is produced in different variations, for maximum harmonization with certain types of construction work.
Concrete, implicated Portland -chamber, can turn out either the so -called “hard” or not. This, as a rule, depends on the properties of the cement itself. Over the years of construction practice, there has been a certain popularity among cement with the M-400 labeling and the M-500 ″. This happens due to the fact that possessing the most necessary qualities, they are both enough accessible to the vast majority of developers.
Cement, easily preserved for a long time in this case and without losing active properties, the manufacturer denotes a hydrophobic. He receives these qualities due to his composition, namely, of the small number of active natural special. additives. Hydrophobic cement mainly produced two types of 300 and 400.
The construction of country buildings is usually always based on such cement as sulfate -resistant, which easily resists any corrosion. It is indicated as follows: M-300, M-400. Also, without sulfate cement, the construction of cottages is not complete.
Slag-Portland cement is used to knead waterproof concrete. And if it is necessary to apply a “color” Portland cement one of two-either M-400, or M-500.
