    How to improve and factors affecting Workability of Concrete

    Workability is one of the physical parameters of concrete which affects the strength and durability as well as the cost of labor and appearance of the finished product. Concrete is said to be workable when it is easily placed and compacted homogeneously i.e without bleeding or Segregation. Unworkable concrete needs more work or effort to

  • 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

  • Blended Cement in Malaysia

    In Malaysia, regarding the cement specifications on use of blended cement with 25% Fly-Ash, cement supplier sometimes will propose on use of Ground Granulated Blastfurnace Slag (GGBS) as an alternative to Fly-Ash based on the logistic reasons, location of factory, stock available & etc. 25% Fly-Ash specified in the project will fall under CEM IIB-V

  • 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

  • Temperature rise in concrete

    In Malaysia, generally for 1m3 size concrete ~ the rule of thumb is about 13.5°C/100kg Portand Cement (OPC), for 380kg cement content, the temperature rise will be 51.3°C + 30°C or equal to 81.3°C.   If blended cement is used, the temperature rise will be proportionately lower. As the specification always allows the use of
