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+C2S77%, 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 important structure high strength concrete and prestressed concrete project, like as bridge, wharf, road, airport, high rise building and other large concrete construction works, and also for ordinary industrial and civil construction engineering.
