關于國標白水泥的基本知識你了解多少？國標白水泥是眾多的白水泥中的一種，而在制作的過程中要使其產品它符合國家的相關標準，其中對于產品的技術性的要求包括了哪些下面就跟隨貴陽白水泥廠家一起來了解吧！
How much do you know about the basic knowledge of GB white cement? The national standard white cement is one of the many white cement. In the process of making the white cement, it is necessary to make its product conform to the relevant standards of the state. The technical requirements of the product include what follows from the Guiyang white cement manufacturer.
一、國標白水泥中的不溶物
1. Insoluble compounds in national standard white cement
不同的水泥產品中的不溶物標準不一樣，其中有不得超過0.75%、1.50%等區(qū)別。
The standard of insoluble substances in different cement products is different, and there should be no difference between 0.75% and 1.50%.
二、燒失量
Two. Heat loss
白水泥中的燒失量不得大于3.0％、3.5％。普通水泥中燒失量不得大于5.0％。
The loss of ignition in white cement shall not exceed 3% and 3.5%. The burning loss in ordinary cement should not be more than 5%.
三、氧化鎂
Three. Magnesium Oxide
國標白水泥中的氧化鎂的含量不宜超過5.0％。如果水泥經壓蒸安定性試驗合格，則水泥中氧化鎂的含量允許放寬到6.0％。
The content of Magnesium Oxide in GB white cement should not exceed 5%. If the cement is qualified by autoclaved stability test, the content of Magnesium Oxide in cement will be relaxed to 6%.
四、三氧化硫
Four, three sulphur oxide
三氧化硫的含量不得超過3.5％。
The content of three sulphur oxide should not exceed 3.5%.
五、細度
Five, fineness
國標白水泥比表面積大于300m2/kg，普通水泥80m方孔篩篩余不得超過10.0%。
The national standard white cement specific surface area is larger than 300m2/kg, and the normal cement 80m square hole sieve can not exceed 10%.
六、凝結時間
Six. Setting time
初凝不得早于45min，終凝不得遲于6.5h，普通水泥初凝不得早于45min，終凝不得遲于10h。
The initial setting shall not be earlier than 45min, the final solidification shall not be later than 6.5h, the ordinary cement initial setting shall not be earlier than 45min, and the final solidification shall not be later than 10h.
七、安定性
Seven, stability
可以用沸煮法檢驗必須合格。
It can be tested by boiling method.
八、強度
Eight, strength
國標白水泥強度等級按規(guī)定齡期的抗壓強度和抗折強度來劃分，各強度等級水泥的各齡期強度不得低于標準值。
The strength grade of GB white cement is divided according to the compressive strength and flexural strength of the specified age. The strength of every strength grade cement must not be lower than the standard value.
