Crossing and coating in construction

Why are construction coatings needed and overlapping

In the construction of high -altitude structures, when arranging ceilings on metal beams, it is frozen with the subsequent covering of the sealing places with elastic air permeable films.

To highlight the joints of prefabricated coatings and ceilings, it is recommended to use a solution of brand 100 or concrete of a brand 150 on expanding cement and small aggregate. At a negative temperature, it is advisable to introduce hardening accelerators into solutions. Repayment of shrinkage phenomena and increasing the degree of adhesion of solutions with reinforced concrete elements can be achieved by plasticized cements with the introduction of sulfide-synoport bard in the amount of 0, 15% of the mass of cement.
