本文研究了碱矿渣(JK)混凝土的抗渗性、抗碳化性、抗冻性、抗蚀性、护筋性及碱集料反应等耐久性问题,表明JK混凝土在许多方面都有优异的性能。论述了JK混凝土的耐久性与混凝土结构与相组成的关系,讨论了发展高强高耐久混凝土的途径。
This paper studied the durability problems of alkali-slag (JK) concrete such as impermeability, carbonation resistance, frost resistance, corrosion resistance, tendon reinforcement and alkali aggregate reaction, indicating that JK concrete has excellent performance in many aspects. . The relationship between the durability of JK concrete and the concrete structure and phase composition is discussed, and the way to develop high strength and high durability concrete is discussed.
