Product Description

we sell all kinds of cement locally and internationally, Types of Cement There are three types of cement Portland cement Blended Cement Hydraulic Cement Portland cements are hydraulic cements composed primarily of hydraulic calcium silicates. There are 8 types of Portland cement Type I and Type IA General purpose cements suitable for all uses where the special properties of other types are not required. Type IA is air entrant. Type II and Type IIA Type II cements contain no more than 8% tricalcium aluminate (C3A) for moderate sulfate resistance. Type IIA is air entrant. Type III and Type IIIA Chemically and physically similar to Type I cements except they are ground finer to produce higher early strengths. Type IIA is air entrant. Type IV Used in massive concrete structures where the rate and amount of heat generated from hydration must be minimized. It develops strength slower than other cement types. Type V Contains no more than 5% C3A for high sulfate resistance Blended hydraulic cements are produced by intimately and uniformly inter-grinding or blending two or more types of fine materials. The primary materials are portland cement, ground granulated blast furnace slag, fly ash, silica fume, calcined clay, other pozzolans, hydrated lime, and pre-blended combinations of these materials. There are 5 types of Blended Cement Type IS-Portland blast furnace slag cement Type IP and Type P-Portland-pozzolan cement Type I(PM)-Pozzolan-modified Portland cement Type S-Slag cement Type I(SM)-Slag-modified Portland cement All Portland and blended cements are hydraulic cements. "Hydraulic cement" is merely a broader term. There are 6 types f Hydraulic cement Type GU-general use Type HE-high early strength Type MS-moderate sulfate resistance Type HS-high sulfate resistance Type MH-moderate heat of hydration Type LH-low heat of hydration and many others
