1953年,安徽华阳闸混凝土工程施工中,前长江水利委员会下游工程局与南京工学院合作进行了水泥混合材——烧粘土水泥的试验研究,取得了一定成绩和经验。从所得结果来看,烧粘土水泥有很多优点,它在国民经济上有着巨大的作用,有必要进行更加深入的研究。同时,据了解汉江丹江水库地区,出产大批天然水硬性混合材的可能性很小,但却易得到大批粘土材料,在丹江水库混凝土工程中使用烧粘土水泥的可能性的研究,也是一个有现突意义的问题。因此,我们把这次烧粘土水泥(包括青砖水泥)的试验研究,分作材料、物理、化学性质、问题讨论、烧粘土水泥的优点和在大体积混凝土的使用问题等方面,加以介绍说明,并提出一些意见供有关方面的参考。但因限于当时试验研究中的某些客观条件和我们自己的认识水平,不当之处还希同志们指正。本文将“烧粘土火山灰质矽酸盐水泥”简称为“烧粘土水泥”。并同时将同原料的“青砖粉水泥”也作了比较试验。
In 1953, Anhui Huayang sluice concrete construction, the former Yangtze River Water Conservancy Commission and Nanjing Engineering Institute downstream engineering conducted a cementitious material - clay cement test, and achieved some results and experience. From the results obtained, burnt clay cement has many advantages, it has a huge role in the national economy, it is necessary to conduct more in-depth study. At the same time, it is understood that there is little possibility of producing a large amount of natural hydraulic mixture in the Hanjiang Danjiang Reservoir. However, it is easy to obtain a large amount of clay materials and the possibility of using burned clay cement in Danjiang Reservoir concrete project is also a There are salient questions. Therefore, we introduce the experimental study of this clay-fired cement (including brick cement) as material, physical and chemical properties, discussion of the problems, the advantages of clay-fired cement, and the use of mass concrete, etc. , And put forward some suggestions for reference by relevant parties. However, due to the limitation of certain objective conditions and the level of our own understanding in the experimental study at the time, the comrades also hoped to correct them. In this paper, “burned clay pozzolanic cement” is simply referred to as “clay burial cement.” At the same time with the raw materials of “brick powder cement” also made a comparative test.
