    SLAGCEM  
   

SLAGCEM is the brand name of the high quality Portland Slag Cement / Blast Furnace Cement produced by blending Ground Granulated Blast Furnace Slag (GGBS) with Ordinary Portland Cement (CEM I).

 
       
 

CERTIFICATIONS

Portland Slag Cement is certified to CEM II/B-S 42.5N (21% to 35% Blast Furnace Slag). Blast Furnace Cement is certified to CEM III/A 42.5L (36% to 65% Blast Furnace Slag) as well as CEM III/B 32.5N - LH/SR (66% to 80% Blast Furnace Slag). CEM III/B 32.5N - LH/SR is certified as Low Heat (LH) and Sulfate Resistance (SR) Cement.

APPLICATIONS

Portland Slag Cement is suitable for application in moderate heat of hydration, moderate sulfate resistance, water retaining structures, basement and other structures which require moderate low heat of hydration.

Blast Furnace Cement is suitable for applications in marine environment, mass concreting, sulfate environment, water retaining structures, basement and other structures which require low heat, sulfate resistance and chloride resistance.

 
PROPERTIES



 
ENVIRONMENTAL BENEFITS

As granulated blast furnace slag is a by-product from the steel manufacturing process, by using GGBS to replace 30%, 50% and 70% of cement, significant amount of CO2 emission will be eliminated.

  AVAILABILITY

Portland Slag Cement and Blast Furnace Cement are available in bulk from YTL Westport & Pasir Gudang cement plants.


QUALITY ASSURANCE

Portland Slag Cement and Blast Furnace Cement are produced under stringent quality assurance, environment management, health & safety and energy management systems. It is certified to MS ISO 9001, MS ISO 14001, OHSAS 18001 & MS ISO 50001.
