Features:

High strength, high steady, high quality, low fluctuate

High purity limestone material, with advanced Pyro-Rapid pre-calcine, pre-heating technology.

By advanced X-ray fluorescence analyzer, we can get ingredient quickly and make ingredient steady.

Dry method equipment imported from Germany KHD, make clinker aggregate excellent quality. (C₃S+C₂S over77%, C₃A≈8%, C₄AF≈12%)

Freeze proof, abrasion resistance, low slump constant.

Attention:

Store carefully, avoid moisture.

Not mix with different type cement together.

Select cement type and grade as real condition.
