The invention discloses heat-resistant concrete which is prepared from the following raw materials: Portland cement, coal ash ceramsite slag, silicon powder, high-alumina refractory brick aggregate, basalt particles, glass beads, boron phosphide powder, a high-temperature-resistant inorganic nano composite binder, a heat-resistant high polymer material and the like, has the advantages of light weight, low heat conductivity and good heat stability, and is excellent in heat insulation performance. The heat resistance of the concrete is improved, so that the concrete does not crack at a relatively high temperature, and the loss of compressive strength is reduced; the high-temperature-resistant inorganic nano-composite binder and the heat-resistant high polymer material can ensure that a concrete product can still keep overall stability under the heating condition, and the process for preparing the concrete comprises the steps of binder preparation, concrete dry material preparation, fine material soaking, heat-resistant concrete mixing and casting molding and the like. All the components are tightly bonded with one another, so that the overall bonding strength is improved, and the compactness of finished concrete is improved.
本发明公开了一种耐热混凝土，其原料组成包括硅酸盐水泥、煤炭灰陶粒渣、硅粉、高铝质耐火砖骨料、玄武岩颗粒、玻化微珠、磷化硼粉末、耐高温无机纳米复合粘结剂、耐热高分子材料等，具有质轻、热导率低、热稳定性好的优点，隔热性能佳，提高混凝土的耐热性能，使混凝土在较高温度下，不出现裂纹，抗压强度损失减少；耐高温无机纳米复合粘结剂和耐热高分子材料可保证混凝土产品在受热情况下依然能够保持整体稳定性，制备该混凝土的工艺中包括粘结剂制备、制备混凝土干料、细料浸泡、耐热混凝土拌和浇注成型等步骤，保证各个成分之间相互紧密粘结，从而提高整体粘结力度，增加成品混凝土的致密性。
