  • Type of cement used in Marine

    For type of cement to be used in marine conditions, there is the latest BS 8500-1:2006 + A1:2012. In Malaysia, this British Standard is also adopted into MS 523-2:2011 Concrete Specification. Please refer to the extract of BS 8500-1:2006 + A1:2012, marine conditions is under Exposure Classes XS1- XS3 (Table A.1) . Hence, considering the

  • 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

  • Blastfurnace Cement as an alternative to Sulphate Resisting Portland Cement (SRPC)

    In practice, cement supplier will counter propose to the contractor the use of an equivalent product for Sulphate Resisting Portland Cement (SRPC) which is Blastfurnace Cement complying to MS EN 197-1, CEMIII/B. One of the advantage is due to the pricing issues (Blastfurnace Cement is much cheaper). Blastfurnace Cement usually is manufactured with the combination of

  • Production of Blastfurnace Cement

    Blastfurnace Cement is a special blend of two components; ground granulated blastfurnace slag (GGBS) and portland cement (OPC). GGBS is a by-product of the iron-making process in a blastfurnace. It is produced by the rapid water-quenching of the molten slag under controlled conditions. This granulation process yields sand-sized particles of highly glassy material of high

  • Use of Blastfurnace Cement for Sulphate Resisting Properties

    1) Sulphate Resisting Portland Cement (SRPC) & ASTM Type V Cement SRPC is a costly and special type of cement where in the manufacturing process, one of the major compound i.e. tricalcium aluminate (C3A), is limited to < 3.5 %. Whereas for ASTM Type V cement, the maximum C3A content allowed is 5%. This C3A

  • What is low heat cement?

    Hydration of cement is an exothermic process that produces large quantity of heat. In mass concrete structures such as dams, retaining walls, bridge abutment, raft and etc. the rate of dissipation of heat of hydration from the surface is much lower than that generated. It causes rise in temperature inside the concrete mass and may
