Heat-resistant concrete formula for improving rheological property and preparation method thereof
The invention belongs to the field of building construction, particularly relates to a heat-resistant concrete formula for improving rheological property and a preparation method thereof, and solves the problems of poor rheological property and easy generation of cracks during solidification in the prior art. The concrete is prepared from eight raw materials including Portland slag cement, graystone, granulated blast-furnace slag, fly ash, 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: 5-15% of Portland slag cement, 15-17% of graystone, 10-20% of granulated blast furnace slag, 5-15% of fly ash, 10-13% of a water reducing agent, 30-35% of water, 3-5% of an early strength agent and 5-7% of wollastonite. Sequentially adding the Portland slag cement, the graystone, the granulated blast furnace slag, the fly ash, the water reducing agent, the early strength agent and the wollastonite into the stirrer, and carrying out uniform dry mixing.
本发明属于建筑施工领域，具体涉及一种改善流变性的耐热混凝土配方及其制备方法，解决了现有技术中存在流变性能差，凝固时容易产生裂缝的问题，包括以下步骤确认原料种类，矿渣硅酸盐水泥、玄武石、粒化高炉矿渣、粉煤灰、减水剂、水、早强剂以及硅灰石共八种原材料，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：矿渣硅酸盐水泥5％～15％、玄武石15％～17％、粒化高炉矿渣10％～20％、粉煤灰5％～15％、减水剂10％～13％、水30％～35％、早强剂3％～5％、硅灰石5％～7％，先使用搅拌机搅拌一次，给设备进行涮膛，开动搅拌机，向搅拌机内依次加入矿渣硅酸盐水泥、玄武石、粒化高炉矿渣、粉煤灰、减水剂、早强剂、硅灰石干拌均匀。
