  • What is Silica Fume?

    Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. One of the most beneficial uses for silica fume is in concrete. Because of its chemical and physical properties, it is a very reactive pozzolan. Concrete containing silica fume can have very high strength and can be very durable. Silica fume is available

  • 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

  • GGBS and Fly Ash in Malaysia

    In MS EN 197-1 on cement specifications stipulates 27 common cement, where both Ground Granulated Blastfurnace Slag (GGBS) and Fly Ash are two commonly ‘recycled’ materials used to partially replace Portland Cement (OPC) in cement production. These materials are also pozzolanic in nature i.e. they consume the lime from OPC hydration to form additional cementitious

  • GGBS or Fly Ash in Concrete Batching Plant

    In Malaysia, cement manufactured will propose the use of pre-blended cement instead of supplying Portland Cement (OPC) mix with Ground Granulated Blastfurnace Slag (GGBS) or Fly Ash to concrete batching plant. The main reasons are less hassle and less problems in site batching. However, in most of the main concrete batching plant, they are having

  • Layers in the construction of a mortarless pavement: A. Subgrade B. Subbase C. Base course D. Paver base E. Pavers F. Fine-grained sand
    What is Base Course?

    The base course or basecourse in pavements is a layer of material in an asphalt roadway, race track, riding arena, or sporting field that is located directly under the surface layer. If there is a subbase course, the base course is constructed directly above this layer. Otherwise, it is built directly on top of the
