粉煤灰及矿粉在大体积混凝土中的应用

On application of fly ash and mineral powder in mass concrete

研究了粉煤灰及矿粉在大体积混凝土中的应用,对比了矿粉混凝土与普通混凝土的特点,得出了大体积混凝土采用双掺粉煤灰和矿粉的新技术能节约成本、减小温度应力,提高混凝土的抗氯离子渗透性、抗硫酸盐性和抗碱—集料反应性的结论。

The paper studies the application of the fly ash and mineral powder in mass concrete, compares the characteristics of the mineral powder with others, concludes the adoption of the double mixed with fly ash and mineral powder new technique in mass concrete can save costs, reduce temperature stress, improve the chloride penetration-resistant property, as well as the sulfate resistance and alkali-resistant aggregate reactivity.
