1- Type I Portland Cement .

Description :

This type of cement has recently been upgraded from the resistance class of 1-325 which was produced previously . to the resistance class of 1-425 the improved 1-425 has considerably increased the resistance for type I cements .the production of the 1-425 cement is gone through the testing stages in order to obtain the seal of standard .

Uses :
The type I cement can be used for all purposes . because of high resistance of this cement its use more suitable for those purposes which requires high primary resistance . such as blocks markers prefabricated beams and Etc….

Advantages :
Great mechanical resistance . its three days primary resistance can even meet the standard requirements for type III cement . it has moderate resistance for preventing corrosion of chlorine . its price is fair and economical because less cement is used in designing concrete mix .

Limitations :
For those purpose which the concrete is exposed to the existing sulphates in soil or water (for example the sea water ) C150 AStM Standard & 389 ISIRI Standard .
