Title of the articleOptimization of composition of cement concrete for airfield coverings
Abstract.Modern production of construction materials even more often is guided by use of cheap mineral fillers. They are used both by production cement knitting, and as additives in commodity concrete. Thus fillers not only allow to reduce the cost of these materials, but also to improve their physicomechanical indicators. For example, possibility of decrease in growth of tension is provided at cement structurization, uniformity on durability and a deformativnost increases, energy of growth of cracks, etc. is absorbed. We studied possibility of application as a cheap filler of a calcareous flour for concrete of airfield coverings. Proceeding from requirements imposed to this concrete on durabilities on stretching at a bend (Bt4,8), frost resistance (F200), a class for durability on compression (B40) and to airinvolvement (GOST 26633-91), the supersoftener, an airinvolving additive and a basalt fiber were also used. It is as a result received that without prejudice to these indicators, introduction of a calcareous flour instead of cement for 15 % is possible. At addition of 10 % of a flour some growth of durability on stretching is provided even at a bend probably owing to consolidation of structure of concrete. As a whole, use of a calcareous flour is positively reflected in properties of cement concrete and therefore it can be recommended for partial replacement of cement and decrease in prime cost of a roadbed.
Keywords.Fillers, cement concrete, durability on stretching at a bend, a basalt fiber, supersofteners.
