Properties of lightweight dry masonry mixtures for winter conditions
The construction of building envelopes using effective small-piece elements requires the use of lightweight masonry mortars, obtained, as a rule, from dry mixtures. One of the most effective ways to obtain such mortars is the introduction of hollow ceramic microspheres into their composition as a lightweight filler. For the climatic conditions of the Russian Federation, it is relevant to use dry masonry mixtures in the winter version, which gain strength at negative temperatures. The main purpose of this work was the development of optimal compositions of modified dry masonry mixes with hollow ceramic microspheres and antifreeze additives for use in winter conditions. Determination of the main properties of dry mixes and masonry mortars was carried out according to standard methods. X-ray diffraction and scanning electron microscopy were used to research of the microstructure and phase composition of the materials. As a result of this research, the compositions of the lightweight dry masonry mixtures for winter conditions were developed. The main properties of the mortar mixtures and mortars were determined and structure and composition of new phases of cement stone were studied as well.
