High-strength heat-resistant concrete and production process thereof
The invention belongs to the field of building construction, particularly relates to high-strength heat-resistant concrete and a production process thereof, and solves the problems that in the prior art, the high-temperature strength, refractoriness and thermal stability are too low, and the linear expansion coefficient is high. The refractory brick is prepared from seven raw materials including refractory brick particles, silicate, Portland slag cement, a water reducing agent, water, an early strength agent and wollastonite. Every cubic meter of the heat-resistant concrete finished product is prepared from the following eight raw materials in percentage by weight: 50-80% of refractory brick particles, 10-30% of silicate, 10-30% of slag Portland cement, 10-13% of a water reducing agent, 30-35% of water, 3-5% of an early strength agent and 5-7% of wollastonite, and the heat-resistant concrete finished product mainly comprises cement, aggregate, an admixture, an additive and water, the mineral composition determines the stability and durability of the concrete at high temperature, and the aggregate is used for improving the strength and durability of the concrete.
本发明属于建筑施工领域，具体涉及一种高强度耐热混凝土及其生产工艺，解决了现有技术中高温强度和耐火度以及热稳定性过低，且线膨胀系数较高的问题，包括以下步骤确认原料种类，耐火砖颗粒、硅酸盐质、矿渣硅酸盐水泥、减水剂、水、早强剂以及硅灰石共七种原材料，按照每立方米耐热混凝土成品对以上八类原料按重量进行配比：耐火砖颗粒50％～80％、硅酸盐质10％～30％、矿渣硅酸盐水泥10％～30％、减水剂10％～13％、水30％～35％、早强剂3％～5％、硅灰石5％～7％，主要包括水泥、骨料、掺和料、外加剂和水，水泥是耐热混凝土的主要原材料之一，其矿物组成决定了其在高温下的稳定性和耐久性，骨料用于增加混凝土的强度和耐久性。
