Composite Rapid Hardening Sulpho Aluminate Cement (32.5)

Introduction
The product obtained by grinding cement clinker obtained by roasting suitable raw material, consisting essentially of anhydrous calcium sulphoaluminate, dicalcium silicate and teraclcium aluminate ferrite. Suitable anhydrite、slag and fly ash shall be blended with clinker during manufacture of improved rapid-hardening sulphoaluminate cement. It has high early strength. The product is hydraulicity binding material. The code is I-SAC.

The product carries out the standard: Q/ZTS01-1999.

The strength depends on its compressive strength at 7 days. There are two grades: 32.5 and 42.5.

The product achieved a class one civic prize of excellent new product, a class two provincial prize of excellent new product. The product is high -tech product by Hebei science department.
Properties

 

◇  It can extend the working time, improve the concrete workability, early strength, rapid hardening, freeze- resistance, impermeability and little expansion etc.

◇  Improving the sulphoaluminate cement that easy occurring sands in surface for incorrect curing.

◇  The price is low.

◇  Setting time is a little longer than R-SAC(Rapid-hardening sulphoaluminate cement),quite suit for RMC.
