Description

(54) BUILDING SOLUTION

The invention relates to building materials, in particular to building mortar compositions containing modifying additives.

Known mortar, including mineral hydraulic sticking, aggregate, water and plasticizing additive - 60-70% alkaline solution of the total wood resin in the amount of 0.2-0.6% by weight of the mineral sticking 1.

j most closely related to the invention in its technical essence and the achieved result is a mortar 2 comprising, in wt%:

The known construction solutions have insufficient plasticity and lose it almost completely within 2 hours. In addition, they have high water separation and water absorption.

The purpose of the invention is to increase the plasticity of the solution and preserve it in

time, as well as reduced water release and water absorption.

The goal is achieved by the fact that a mortar & p, including cement, sand, one stripped off afterburned molasses bard, sodium methylsiliconate and water, additionally contains silica gel - waste cryolite production in the following ratio of components, wt.%:

Cement 6-11

Sand 73-78

The mortar is prepared as follows. Supplements are mixed.

and then they are introduced into the mixture of cement and aggregate with mixing water.

Specific examples of implementation are given in table. one..

Physical and mechanical properties of the proposed and known solutions are given in -tabl. .2.

The proposed mortar has a frost resistance of 1.5-2 times more than known. Cement Sand Moulassna one stripped off afterwards, 020.040.02 chew bard Methylsiliconate 0.010.030.01 sodium Cryolite silica waste 0.100,400.25 production 15.8715.5314.72 Notices ..
