【摘要】 对高性能混凝土的重要指标——耐久性进行试验研究,设计正交试验,利用极差对试验结果进行分析,找出各因素水平对抗冻性能的影响规律,优选出最佳配合比A1B2C1D3,制备出了高抗冻融混凝土并进行了生产实践,取得了良好的效果。更多还原

【Abstract】 In this paper,an important indicator of high performance concrete—durability test is made,the orthogonal experiment is designed based on the polar difference,the test results are analyzed,finds the influence law of various factors effected on the level of freeze-thaw resistance,optimizes the mixture ratio A1B2C1D3,prepares high freeze-thaw resistance concrete and does the production practices,which have achieved good results.更多还原
