贵阳白水泥厂家水泥的常规知识及其说明

我们所知到常用的水泥有硅酸盐水泥、普通硅酸盐水泥(简称普通水泥)、矿渣硅酸盐水泥(简称矿渣水泥)、火山灰质硅酸盐水泥(简称火山灰质水泥)、粉煤灰硅酸盐水泥(简称粉煤灰水泥)。此外.还有特殊功能的水泥,如高强、快硬、耐酸、耐热、耐膨胀等不同性质的水泥以及装饰用的白水泥(贵阳白水泥)等。

The common cement is Portland cement, ordinary portland cement (ordinary cement), slag Portland cement (slag cement), volcanic ash Portland cement (abbreviated as ash cement) and fly ash Portland cement (fly ash cement for short). In addition, there are special functions of cement, such as high strength, fast hard, acid resistant, heat-resistant, resistant to expansion and other different properties of cement and decorative white cement (Guiyang white cement).

水泥强度等级:水泥强度等级按规定龄期的抗压强度和抗折强度来划分,以28夭龄期抗压强度为主要依据。根据水泥强度等级,将水泥分为32.5,32. 5R, 42. 5,42. 5R,52.5, 52.5R, 62.5. 62.5R等几种。

Cement strength grade: the strength grade of cement is divided according to the compressive strength and flexural strength of the specified age, and the compressive strength of the 28 age is the main basis. According to cement strength grade, cement is divided into 32.5,32. 5R, 42. 5,42. 5R, 52.5, 52.5R, 62.5. 62.5R and so on.

水泥的特性:

The characteristics of cement:

水泥具有与水结合而硬化的特点,它不但能在空气中硬化.还能在水中硬化,井继续增长强度.因此,水泥属于水硬性胶结材料。水泥经过初凝、终凝,随后产生明显强度.并逐渐发展成坚硬的人造石,这个过程称为水泥的硬化.

Cement has the characteristics of hardening with water. It can harden in the air. It can also harden in water, and the well continues to increase strength. Therefore, the cement is a hard cementing material. After the initial solidification and final solidification, the cement will produce obvious strength and gradually develop into a hard artificial stone. This process is called hardening of the cement.

水泥的保管:水泥属于水硬材料,必须妥善保管,不得淋雨受潮。贮存时间一般不宜超过3个月。超过3个月的水泥(快硬硅酸盐水泥为1个月),必须重新取样送检,待确定标号后再使用.

Preservation of cement: Cement belongs to water and hard material. It must be properly kept and not wet. The storage time should not be more than 3 months. For more than 3 months, cement (fast hard Portland cement for 1 months) must be re sampled for inspection before being identified.
