VICEM HA TIEN PORTLAND BLENDED CEMENT PCB50 is a fine powder mixture of various minerals. It is produced by mixing calcareous minerals such as limestone, clay containing silica and alumina and heating it to 1450°C. When it cools, a clinker is formed. This clinker is then finely ground and mixed with gypsum and others activated mineral additives such as Puzzolan, limestone, fly ash, blast furnace slag, silica fume. The activated mineral additives have the ability to disperse, fill the pores, increase the early strength and the waterproofing of concrete.
USES
VICEM HA TIEN PORTLAND BLENDED CEMENTS PCB50 is used widely for all constructions from residential house to high-rise building or industrial projects... PCB50 is suitable to all technical requirements when making concrete and mortar with high quality.
Advantage of Vicem Ha Tien PCB50 is the high early strength which can help to shorten the time from placing concrete to removing the form-work, saving the construction time and cost.
For projects with special requirements of concrete to resist the erosion form water, chemical... PCB50 is the one of the best options.
In addition to the development of early strength, VICEM HA TIEN Portland Blended cement PCB50 also has high late strength to ensure the durable of construction.
