Description

one

The invention relates to compositions of building solutions containing complex additives of polyfuncial action, and can be used in p), residential, civil and rural construction.

A known concrete mixture containing cement, aggregate, water, and chalk. A fresh steamed yeast bard in an amount of 0.1-0.25% by weight of cement.

The disadvantage of this mixture is small, shelf life, low strength and frost resistance of the resulting concrete.

Closest to the proposed mortar is a concrete mixture.2, including cement, silica sand, crushed granite, the addition of organosilicon compounds, molasses, and. water in the following ratio of components. May %: Cement280-400

Quartz sand 625-730

Crushed granite 1200

Organosilicon compound

The disadvantage of such a concrete mix is the relatively low viability of the mix, the strength and frost resistance of concrete.

The purpose of the invention is to increase the viability of the mortar mixture, as well as compressive strength and frost resistance of the solution.

The goal is achieved by the fact that a construction solution, including cement, sand, a silicone compound, a melass-containing additive and water, contains methylsiliconate as the silicone compound.

Example. The following 30 materials are used to prepare the proposed and well-known construction solutions: mortar cement M-300 from the Dneprodzerzhinsky plant; quartz sand with a modulus of size 1.3} organosilicon compound NGL-10) / molasses; the molasses is evaporated after baking and the methylsiliconate sodium. The complex additive is added together with water in the mix. Measurement of the mobility of mortar mixes over time (viability is made by holding them in air at 15-25 ° C and relative air humidity of 50-60%. To determine the strength and frost resistance of the mortar, cubic samples are made that are tested at the age of 28 days of normal hardening. The composition of the mortar is given in Table 1. Tables 2 and 3 show the results of testing samples based on the known and proposed solutions, the proposed solution has an increased viability of the mixture, and also Compressiveness and frost resistance. The mortar can be used in construction with its centralized preparation, increased transportation distance and storage in on-site conditions. T a b i c a 1
