Composite Portland cement 32.5 32.5R

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 ordinary civil and public constructions, real estate and hydraulic engineering. Especially for ordinary prefabricated parts and concrete, also for building mortar, masonry, marble inlaying, tiling etc

Packaging：

50kg per bag, 40 bags into a 2MT jumbo bag; or as your requirements
