山道尔·波波维奇(Sandor Popovics)教授,于本刊1982年第六期上发表了《海洋环境中钢筋混凝土耐久性的改进》之后,曾在国内混凝土界引起广泛注意。1983年末,受联合国工业发展组织的推荐,波波维奇教授再次来到中国,于上海进行学术讲座,并与上海市建筑科学研究所一起进行了粉煤灰混凝土的试验工作。本文是波波维奇教授来华讲学的主要内容之一。文中提出了粉煤灰混凝土的配合比公式及其最优化步骤。虽然这些公式没有排除在配合比设计中试拌的必要性,但运用这些公式能够减少试拌的次数,并对进一步的实验和分析工作有积极的指导作用。
Prof. Sandor Popovics, who published the “Improvement of Reinforced Concrete Durability in the Marine Environment” in the 6th issue of 1982, has caused extensive attention in the domestic concrete community. At the end of 1983, recommended by the United Nations Industrial Development Organization, Prof. Popovich once again came to China to give lectures in Shanghai, and conducted fly ash concrete test work with the Shanghai Institute of Building Science. This article is one of the main contents of Professor Popovich’s lecture in China. In this paper, the mix formula of fly ash concrete and its optimization steps are proposed. Although these formulas do not exclude the necessity of mixing in the mix design, the use of these formulas can reduce the number of test mixes and provide a positive guide to further experiments and analysis.
