Product Description

TBT steam autoclave pressure cement stability (digital display type)


Product Description


I. Introduction


It is widely used in cement production ,building materials research institutes, universities and construction quality inspection departments for the determination of cement MgO (magnesium oxide) on the cement stability of the adverse effects of special equipment.


The performance of cement and its test showed that the content of MgO in cement clinker was mainly brought into limestone raw material, and MgO was mostly granite when the clinker was burned. I


ts structure is dense (commonly known as dead burning state), and wrapped in the middle of clinker minerals, and water reaction speed is very slow.


It is generally believed that after 10 to 20 years or more, hydration is continued to produce Mg (OH) 2, the solid volume is increased by 2.48 times, and the local volume expansion has a great destructive stress in the hardened cement.


With boiling cake 100 ℃ boiling 3h can not make a lot of hydration of MgO, so boiling method can not test the stability of cement caused by magnesite, high temperature and high pressure conditions can accelerate the clinker in the magnesite hydration, so clinker MgO The poor stability caused by the use of pressure to test the method.
