"This article shows results of experimental program focused on determination of refractory and non-refractory components for cement composites and those influence on final properties. According to several research works from various universities strength and cohesion in general of common concrete rapidly decrease with temperature higher than 600 \u00B0C. To determine the difference between fire-resistance and common components four mixtures were designed. Non-refractory crushed nature silica aggregates and Portland cement compared to high alumina cement Secar\u00AE71 with crushed nature basalt aggregates were used. Combination of basalt fibers with two different lengths significantly improves. Basic mechanical properties tensile characteristics such as tensile strength in bending and compressive strength were examined on samples 40 x 40 x 160 mm. Exposure to 600 \u00B0C and especially 1000 \u00B0C in electric furnace for three hours simulated the high temperature load. Compared to silica aggregates together with Portland cement, where after 1000 \u00B0C the composite is disintegrated with almost zero strength, the refractory components show considerably better parameters." .
