三个优点在我省大规模的水利建设运动中,各地群众曾创造了一些水泥代用品,保证了工程任务的完成。经过我们的试验鉴定,认为采用“烧粘土石灰代水泥”的经验较好,其优点是:(1)能够就地取材,就地制作,且技术亦较简单,易为群众所接受.解决纯水泥供不应求的问题。(2)代水泥虽然在某些主要性能上较纯水泥为差,但它能够在水中结硬,宜于用来建设水利工程(纯石灰只能在空气中结硬,在水中容易崩解),
Three advantages In our province’s large-scale water conservancy construction movement, people from all over the country have created some cement substitutes to ensure the completion of engineering tasks. After our test appraisal, that the use of “clay” for clay "good experience, its advantages are: (1) to local materials, in-situ production, and the technology is also relatively simple and easy to be accepted by the masses. Solve the problem of pure cement in short supply. (2) Although cement is inferior to pure cement in some major properties, it can be used to build water conservancy projects (pure lime can only be hardened in the air and easily disintegrated in water) ,
