OPC 43 Grade Cement

43 Grade Cement is the popular brand cement with low heat of hydration and long life of Concrete Structures.


Develop early strength at 3 and 7 days with exceptionally high 28 days strength. Form work of slabs and beams can be removed much earlier which results in increased speed of construction.

Unbeatable consistency in quality gives better accountability for mix design.

The higher characteristics strength of concrete leads to higher bond strength minimizing the possibility of slippage of reinforcements.

Its high fineness offers better workability for a given water cement ratio ensuring very dense, compact and durable concrete.

Being the low alkali cement it provides insurance against alkali-aggregate reaction, this results in durable structures.

Ideal applications:

Residential and commercial complex.

PCC solid and hollow blocks.

Defense Constructions.


Cement tanks

Asbestos cement products.

Concrete roads and Ferro-cement concrete elements.
