Concrete is one of the most common construction materials. Strength and frost resistance are the main and most important properties of concrete. Frost resistance of concrete is very important for buildings and constructions erected in Russia, since many regions are characterized by harsh climate conditions. These climatic conditions include: low temperatures, fluctuations of both temperatures and humidity. As a result, concrete saturates with water, and after repeated alternating freezing and thawing, concrete may start damage. The idea of my scientific investigation is to develop a new technology of manufacture of the concrete possessing improved technical and operational characteristics, first of all, frost resistance. Within the frames of the present investigation, we studied the available experience of applying silica fume and polymers in concretes in the capacity of modifying additives used to elevate frost resistance. An optimal ratio of the additives was found, and the optimum composition of polymer concrete modified with silica fume was developed. Investigations bound up with determination of the principal physical and mechanical properties have been conducted.
