3. high-density concrete this type of concrete is also called heavy weight concrete. in this concrete type, the density varies between 3000-4000 kgm 3. these types of concrete are prepared by using high density crushed rocks as coarse aggregates. among such materials, barytes is the most commonly used material, which has a specific gravity of ...
Dec 03, 2016nbsp018332this type of cement can be used with advantage in mass concrete work such as dams, foundations, and abutments of bridges, retaining walls , construction in sea water. 10. air entraining cement it is produced by air entraining agents such as resins, glues, sodium salts of sulfate with ordinary portland cement.
Type v when concrete is exposed to highly alkaline soil or water having high sulphate content then this type is used. this cement has a low c3a content so as to avoid sulphate attack from outside the concrete. otherwise the formation of calcium sulphoaluminate and gypsum would cause disruption of conrete due to an increase in volume of resultant compounds.
Type i is ordinary portland cement, and it is available in white or gray. type ii is a moderate sulfate resistant cement, important when concrete is cast against soil that has moderate sulfate levels. type iii is a high early strength cement. it is ground finer and reacts faster than type i, so the early strength gains are greater. however, the ...
Cemex provides high-quality type ii and v cement. type ii is used when moderate sulfate resistance or moderate heat of hydration is required, and when high sulfate resistance is required, type
Jun 27, 2019nbsp018332type n mortar mix . type n mortar is usually recommended on exterior and above-grade walls that are exposed to severe weather and high heat. type n mortar mix has a medium compressive strength and it is composed of 1 part portland cement, 1 part lime, and 6 parts sand.
May 06, 2020nbsp018332the distinct types of portland cement are defined through astm c150-20 standard specification for portland cement, which distinguishes them by purpose. the standard types of portland cement are type i for general purpose type ia same as type i, but when air entrainment is desired type ii for moderate sulfate resistance
Type i cement does not have specified limits on several chemical compounds and has the same limits as type ii for some others. to achieve sulfate resistance and limit heat of hydration, type ii cement limits the content of tricalcium aluminate c3a to 8, and the sum of tricalcium silicate and tricalcium aluminate c3s c3a to 58.
