Research on the Application of Compound Admixture in the Freezing Mine Shaft Lining Concrete

Abstract:

In order to achieve the setting and hardening of mine shaft lining concrete under the minus temperature in freezing construction and to meet the demands of every performance of concrete, the technique of compounding air entraining admixture and antifreezing admixture and early strength water reducing admixture was applied in this research. Based on the orthogonal experimental design, several mix proportions of compound admixture for early strength liquid mine shaft lining concrete were developed in the laboratory. The data collected in this research provide reference for the optimum mix proportion of the adulteration quantity of the concrete admixture. The results show that the 2.1％ amount of compound antifreezing admixture achieves favorable effects of liquid, early strength, freezing prevention and antifreezing.
