Research of the Uniaxial Compressive Property of the Concrete Mixed with High-Content Fly Ash in Seawater

Abstract

This paper studies on the frost resistance of high-content fly ash concrete which content 52 fly ash in seawater. The uniaxial compressive property test was carried out after the fast freeze-thaw test with 0, 100, 200, 300 and 400 cycles. The research analyzed the influence of the uniaxial strength of the concrete mixed with high-content fly ash after freeze-thaw cycles in seawater. Then established a mathematical expression in a simple way. In the real project, the concrete mixed with fly ash can improve the frost resistance. The dosage of fly ash will directly influence the frost resistance and mechanical property. However, there is less study on frost resistance of concrete mixed with fly ash, especially the test under the seawater environment.
