Heat-resistant concrete and preparation method thereof
The invention discloses heat-resistant concrete and a preparation method thereof. The heat-resistant concrete is prepared from the following components in parts by weight: 200 to 300 parts of cement, 50 to 200 parts of mineral admixture, 800 to 1200 parts of fine aggregate, 800 to 1200 parts of coarse aggregate, 140 to 180 parts of water, 5 to 15 parts of polycarboxylate superplasticizer and 5 to 30 parts of heat resistance enhancing component. The heat resistance enhancing component is formed by mixing a polyphosphazene micron tube and a polyphosphazene micron tube dispersion enhancing component according to the weight ratio of 1: 100. The diameter of the polyphosphazene micron tube is 5-15 microns, the length-diameter ratio is 20-40, and the wall thickness is 50-200 nanometers. The polyphosphazene microtube dispersion strengthening component is a mixed solution of 1-ethyl-3-methylimidazole diethyl phosphate salt and methyl hydroxyethyl cellulose, and the weight ratio of the 1-ethyl-3-methylimidazole diethyl phosphate salt to the methyl hydroxyethyl cellulose is 20: 1. The heat-resistant temperature of the heat-resistant concrete reaches 600 DEG C, and the heat-resistant
