Low Heat Portland Cement
(High Belite Cement)
Summary
Low-heat Portland Cement, is one of hydraulic binding materials, also named Low Heat Cement, High Performance Low Heat Cement, or High Belite Cement. Code Number PLH.
Low Heat Cement has excellent performances such as high final strength, sulfate corrosion resistancing, good lasting properties, good resistance to rupture, etc.
Because of its excellent performances for example lower hydration heat, high late strength, sulfate resistancing, anti-seepage and resistance to rupture etc., Low Heat Cement is widely applied in building dam, bank of river, wall of sea, and other hydraulic engineering concrete and marine concrete.
Grade: 42.5
Characteristics
Low heat of hydration: comparing with grade 42.5 portland cement, its value of hydration heat is low about 20%, ultimate value of temperature up is low about not less than 15%, so PLH. is very fit to apply in making mass concrete;
Lower water requirement
High lasting properties
High fluidity
Good volume stabilization
High growth rate of final strength
More high technical strength of concrete
Excellent impact erosion
Excellent wear resistance
Lower temperature upward value of heat insulation
Super-high performance of chemical corrosion resistance: when Low-heat Portland Cement is cured in 3% solution of Na2SO4 for 6 months, its erosion resistance factor is more than 0.97, higher near 1 multiple than Ordinary Portland Cement(OPC), so it has good corrosion resistance performance especial to sulfate. To other erosion medium for example sea water and chloride, its corrosion resistance performance is obviously superior to OPC.
Excellent resistance to drying shrinkage
Good resistance to rupture
