However, these fillers do not have sufficient adhesion strength under conditions of hardening at negative temperatures up to. i The purpose of the invention is to penetrate the adhesion of the putty to concrete under conditions of hardening at a negative temperature up to. .

This goal is achieved by the fact that the putty, including carboxymethyl cellosis, dolomite dust, household soap and water, additionally contains paraforms in the following ratio, wt.%:

The putty is prepared as follows. at once. .

5 Carboxymethylcellulose, household soap and garaform are pre-dissolved in water heated to 40-50 0. Dolomite dust is poured into the cooled solution and the mixture is stirred for 5 minutes manually then 3-4 minutes in a mechanical mixer until a homogeneous mass is obtained . Specific examples of implementation and their physico-mechanical indicators 5 are given in Table. 1 and 2.

The test results show that the adhesion of the putty without steam form slowly increases at low temperatures. Only in 14 days it reaches the values acquired at a positive temperature in 1 day.

The introduction of paraform into the composition of the solution accelerates the structure at a negative temperature. 5 This is especially noticeable when the content of paraform is from t to 3 wt.%.

Intensive structure formation At negative temperature of the putty containing paraphorus, following its strong adhesion to the concrete base, determines the reliability of repair and finishing of reinforced concrete products made in winter. After repair, product 5 can be immediately taken to the open
