Type IV This type of Portland cement is designed to reduce the heat released during hydration This is achieved by reducing the percentage of C 3 A in the cement However, this type has a lower final and initial strength as compared to Type I
5Type IV: low heat of hydration cement this type of cement is not produced anymore in the past, it used for massive structures such as dams the high heat of hydration will cause tensile stresses on concrete and this will lead to cracks nowadays pozzolan and slag are used to control cement temperature
Type IV Portland cement is generally known for its low heat of hydration Its typical compound composition is: 28% (C 3 S), 49% (C 2 S), 4% (C 3 A), 12% (C 4 AF), 18% MgO, 19% (SO 3), 09% ignition loss, and 08% free CaO The percentages of (C 2 S) and (C 4 AF) are relatively high and (C 3 S) and (C 3 A) are relatively low
Type IP PortlandPozzonlan Cement Type IT Ternary Blended Cement In addition, some blended cements have special performance properties verified by additional testing These are designated by letters in parentheses following the cement type
Type IV cement can be used to avoid thermal cracking in mass concrete, by lowering the heat of hydration and hence the internal temperature of the mass but are no longer manufactured in the US In the presence of high concentrations of sulfates in ground waters or soils, the hydration products of C 3 A may undergo further reactions that result in disruptive expansion
Type IV is a low heat of hydration cement for use where the rate and amount of heat generated must be minimized It develops strength at a slower rate than Type I cement Type IV portland cement is intended for use in massive concrete structures, such as large gravity dams, where the temperature rise resulting from heat generated during curing is a critical factor

It’s also the basic ingredient of concrete, which is formed when portland cement creates a paste with water that hardens after binding with sand and rock First discovered by Joseph Aspdin in Leeds, England in the early Nineteenth Century, portland cement
Type IV is a lowheat cement that has been developed for mass concrete construction Normal Type I cement, if used in large masses that cannot lose heat by radiation, will liberate enough heat during the hydration of the cement to raise the temperature of the concrete as much as 50 or 60 F
As a cement category portland cements have various properties, as follows: Type I – normal, no special properties required Type II – moderate sulfate resistant Type III – high early strength Type IV – low heat hydration Type V – high sulfate resistance
