我們所知到常用的水泥有硅酸鹽水泥、普通硅酸鹽水泥(簡稱普通水泥)、礦渣硅酸鹽水泥(簡稱礦渣水泥)、火山灰質(zhì)硅酸鹽水泥(簡稱火山灰質(zhì)水泥)、粉煤灰硅酸鹽水泥(簡稱粉煤灰水泥)。此外.還有特殊功能的水泥，如高強(qiáng)、快硬、耐酸、耐熱、耐膨脹等不同性質(zhì)的水泥以及裝飾用的白水泥（貴陽白水泥）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).
水泥強(qiáng)度等級:水泥強(qiáng)度等級按規(guī)定齡期的抗壓強(qiáng)度和抗折強(qiáng)度來劃分，以28夭齡期抗壓強(qiáng)度為主要依據(jù)。根據(jù)水泥強(qiáng)度等級，將水泥分為32.5,32. 5R, 42. 5,42. 5R,52.5, 52.5R, 62.5. 62.5R等幾種。
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:
水泥具有與水結(jié)合而硬化的特點，它不但能在空氣中硬化.還能在水中硬化，井繼續(xù)增長強(qiáng)度.因此，水泥屬于水硬性膠結(jié)材料。水泥經(jīng)過初凝、終凝，隨后產(chǎn)生明顯強(qiáng)度.并逐漸發(fā)展成堅硬的人造石，這個過程稱為水泥的硬化.
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:水泥屬于水硬材料，必須妥善保管，不得淋雨受潮。貯存時間一般不宜超過3個月。超過3個月的水泥(快硬硅酸鹽水泥為1個月)，必須重新取樣送檢，待確定標(biāo)號后再使用.
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.
