| Title of the article | Studies of the influence of domestic antifreeze additions on the basic properties of mortar |
| Abstract. | In connection with development of construction in winter conditions there is a need to use in masonry mortars supplements with antifreeze effect. At negative temperature such solutions should provide a set of desired strength. Creation of optimal conditions for hardening possible or at positive temperature to achieve a solution of the critical strength (from the economic and technological sides not only appropriate), or, when the temperature of ice formation in the liquid phase. It is known that in order to maintain conditions hardening mortar mixes at low temperatures it is necessary to prevent ice formation in the liquid phase, in order to avoid violation of the structure of freshly prepared solution and, as a consequence, education excess of porosity, low adhesion and strength. The solution is the use of cement masonry mortars with antifreeze additives. This will allow to create conditions for the hydration of cement, to reduce construction terms, reduce energy intensity and complexity of building, as well as to improve the efficiency of buildings. Considered a number antifreeze additives the use of which has allowed to increase the strength of mortar at -18оC on 48-60 %, and increase brand mobility from PC1 to PC2. The introduction of additives antifreeze also led to the reduction of water demand solution to 15-20 %. |
