1.适用的水泥品种 水泥的种类很多,目前我国生产的水泥已有数十种,但多数是属于专门用途的水泥。农村建房最适合采用硅酸盐水泥和普通硅酸盐水泥,因为这两种水泥凝结硬化快、早期强度(28天以前强度)高、耐久性能好。也可采用矿渣硅酸盐水泥,不过因其早期强度低、干缩性大,使用时应加强养护,否则容易使混 1.

The most suitable for rural construction is the use of Portland cement and Portland cement, because these two types of cement have a fast set hardening, high early strength (strength before 28 days), and good durability. Slag Portland cement can also be used, but due to its low early strength and dry shrinkage, it should be strengthened when used, otherwise it is easy to mix
