Heat-resistant refractory concrete and preparation method thereof
The invention relates to heat-resistant refractory concrete and a preparation method thereof, and relates to the field of green building materials. The heat-resistant refractory concrete comprises thefollowing components: 1000-1100 parts of refractory coarse aggregate, 600-700 parts of refractory fine aggregate, 300-400 parts of ordinary Portland cement, 60-120 parts of mineral powder, 30-60 parts of high alumina powder, 7-13 parts of silica powder, 8-12 parts of a polycarboxylate superplasticizer, 1-5 parts of a dispersant and 150-200 parts of water. The preparation method of the heat-resistant refractory concrete comprises the following steps: S1, solid material dry mixing: weighing the raw materials in proportion, mixing and stirring the coarse fire-resistant aggregate, the fine fire-resistant aggregate, the ordinary Portland cement, the mineral powder, the high-alumina powder, the silica powder, the dispersing agent and other powder in sequence from large to small, and stirring for 2 minutes to be uniform to obtain a premixed dry material; and S2, water mixing: sequentially adding a polycarboxylate superplasticizer and water into the premixed dry material obtained in the stepS1, and stirring for 2 minutes to be uniform to obtain the mixed concrete. The heat-resistant refractory concrete has the effects of excellent heat resistance, excellent fire resistance, excellent construction performance and high economic practicability.
