CMS Cement manufactures Ordinary Portland Cement (OPC) and masonry cement.

What is OPC?
Ordinary Portland Cement (OPC) is multi-purpose cement that is most commonly used in general concrete construction. Ordinary Portland Cement is a gray coloured dust. When mixed with water, it hardens into the material used for concrete construction.

CMS Cement Sdn Bhd’s OPC exceeds the quality requirements specified in the Malaysian Standard MS 522 : Part 1: 1989 Specifications for Ordinary Portland Cement.

At CMS Cement, quality is guaranteed. CMS Cement is the winner of multiple national and state awards for quality and best practices. Certification of ISO 9001 : 2000 was achieved on 29 December 1998. CMS Cement's strict quality control at all stages of manufacture as well as stringent testing, control and monitoring procedures ensures the quality of the finished product.


CEMPLAST is the registered brand name for Masonry Cement produced by CMS Cement Sdn Bhd. It is produced by fine grinding a homogenous blend of specified proportions of clinker, gypsum, plasticizing material and an air entraining agent. The special plasticizing material incorporated in CEMPLAST improves its workability and water retention properties and eliminates the need to add hydrated lime to produce a workable, durable and economical mortar. CEMPLAST is designed specifically for producing mortars used for brick/block laying, interior and external rendering and plastering, and other masonry applications.

Manufacturing Process & Raw Materials
The raw materials required for the manufacture of OPC at CMS Cement are clinker (90%), limestone (5%), and gypsum (5%).

As an integrated cement manufacturer, CMS Cement obtains its supply of clinker from CMS Clinker and limestone from CMS Quarries for both its Bintulu and Kuching plants.

The raw materials go through a pre-grinding process that involve processing through the roller press or “polycom” to compact the mixture into units called “cakes.” These are then processed in the “despol” to loosen the substance before the next step.

The next step of manufacture is the separation process of fine and coarse materials via machinery named the ”tube mill” and the “cement separator”. The resulting gray cement dust is collected by the “main bag filter” and is stored in the cement silos.

Despatch & Delivery
CMS Cement’s Ordinary Portland Cement is available in three sizes: Bulk Tanker (ranging between 20-40 tonnes in volume), one-tonne “Jumbo” bags, and 50kg bags. The journey from the silo to the customer is taken by sea or by road via our appointed dealers and strategically placed depots in Miri and Sibu.
