  • The blending of GGBS & Fly Ash in cement

    It is common that incorporating Ground Granulated Blastfurnace Slag (GGBS) and / or Fly Ash in the Portland Cement (OPC). It will be advantages in lowering Rapid Chloride Permeability Test (RCPT) and minimising Alkali Silica Reaction (ASR) risk. In fact, triple blends (OPC / GGBS / Fly Ash) performs better than either the OPC/Fly Ash

  • In term of low temperature, GGBS or Fly Ash better?

    In Malaysia, for temperature control, both partial substitution of Portland Cement (OPC) with Ground Granulated Blastfurnace Slag (GGBS) and Fly Ash reduces heat generation. However, the level of GGBS substitution can be higher, thus the reduction of temperature is higher then Fly Ash. For example, for a 2m thick section, a 30% Fly Ash replacement
