Portland cement  52.5,52.5R

Standard:  GB175-2007, JC/T452-2009, GB/T19001-2008 IDT, ISO9001:2008

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﹥77%, 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

Application range:

For high strength concrete and prefabricated parts, like as road, bridge, etc
