SIGNIFICANCE ANALYSIS OF THE SLAG AND FLY ASH INFLUENCE ON THE STRENGTH OF HIGH-STRENGTH CONCRETE

Through an analysis of the results of the test, this paper discusses the impact of slag and fly ash on the strength of high performance concrete under the conventional material and common technological method. It explains how to make the most appropriate mixture of slag composite admixture, fly ash, water reducing agent, and different water cement ratios. This is turn regulates the relationship of the early strength and the later strength on the premise of satisfying the concrete performance requirement. The best combination in which the function of each component has been put into full use is also found in this paper.
