Description

1The invention relates to building materials, namely to concrete mixes used for road and airfield pavements. Known concrete mixture 1, including, wt.%: Mineral strangling Aggregate 0.04-0.75 Sodium sulfate 0.024-0.375 Potassium chloride The closest to the invention to the technical essence and the achieved result is a concrete mixture comprising cement, crushed stone granite, sand and sludge from chlorine production in the amount of 5-20% by weight of cement. 2 However, concrete prepared from a known concrete mix has low strength in the early stages of hardening. The purpose of the invention is to increase the strength of concrete in the early stages. The goal is achieved by the fact that a concrete mix for road and airfield pavements, including cement, gravel, sand, and waste: chlorine production, contains chlorine hypochlorite pulp with an active chlorine content of 4-8% as a chlorine waste, with the following ratio components, wt.%: Cement12-18 Crushed granite 40-60 Calcium hypochlorite pulp with active chlorine content 4 -8% 5-10 Sand, Rest Calcium hypochlorite pulp is a waste and byproduct of chlorine and chlorine-processing enterprises minutes industry and contains, wt.%; Ca (OCt) 2. 3-5-, Ca (OH) i 7-15; CACCO 2-. H; SiOj - 1-2; MgO 2-3; 0.5-1; rest. Chlorine contributes to a set of strength in the early stages of hardening. Specific examples of execution are given in table. one.
