Low Heat Cement Composition, Properties, Uses and Advantages
Low heat cement is a special tailored cement which generates low heat of hydration during setting It is manufactured by modifying the chemical composition of normal Portland cement In this article we discuss about the composition, properties, characteristics, uses and advantages of low heat cementThe process of hydration is slow and the consequent rate of heat generation is also low It is manufactured from the ingredients of specially selected cement clinker, gypsum and ground granulated blast furnace slag, which result in significantly lower heat generation during the process of hydration than in a typical Portland cementLow Heat Portland Cement, Properties, Uses And
What is lowheat cement and its uses? Quora
Low Heat Portland Cement (LHPC) is Portland cement with lower lower content of rapidly hydrating compounds, TriCalcium Silicate (C3S) and TriCalcium Aluminate (C3A) The process of hydration is slow and the consequent rate of heat generation isThe composition of Low Heat Cement is formulated to deliver lower heat of hydration and superior sulphate resistance This results in slower strength development by the Low Heat Cement, with significantly lower early age strength, but a greater potential for later age strength development Typically the early age strength of concrete containingLow Heat Cement
