Cement is an indispensable basic raw material in the construction of national infrastructure and economic development. However, with the increasing pollution of the environment, the production of cement is still in a high energy consumption industry.
Portland mineral cement is widely used in the market now. Its main components are tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate (C3A), and tetracalcium iron aluminate (C4AF). When mixed with water, the minerals undergo water hydrolysis or hydration reaction to become hydrates. The speed of hydration affects the strength of the cement. Tricalcium aluminate and tricalcium silicate start to set time and early strength of the cement. Decisive effect.
The scope of application of this Portland cement is as follows:
1. Used in general industrial and civil buildings, and can be configured with high-quality concrete and various concrete prefabricated structures.
2. For underground, hydraulic and seawater projects.
3. It is used for high-temperature heating projects and large-volume concrete pouring projects.
The late strength of the cement determines the construction quality, and the Triisopropanolamine （TIPA） has an important effect on the strengthening of the later strength. TIPA increases the strength of limestone portland cement mortar and pulp at all ages, and the latter is significantly enhanced. Due to the dispersion of the limestone powder itself, TIPA strengthens the limestone portland cement better. Whether for Portland cement or Limestone Portland cement, the strength-enhancing effect of TIPA gradually increases with the age.
