Alkali-Silica Reaction in Concrete Engineering Suppression Measures of Inquiry

Article Preview

Abstract:

Local materials was used as raw materials in the test. Test methods are standard test methods. It compared the use of fly ash alone or lithium hydroxide used alone inhibited the effect of alkali-silica reaction, and to a certain percentage of fly ash and lithium hydroxide complex joint effect of inhibiting alkali-silica reaction in the test. The results showed that compound admixtures overcome the shortcomings of the use of fly ash alone or lithium hydroxide inhibition of alkali-silica reaction. It can achieve the goal of complementary advantages.
