TOP 9 TYPES OF CEMENT AND THEIR USES

When it’s cement, we can’t doubt the prowess it possesses. Cement is one of the most useful and widely used building materials in the up-to-date world. Look round yourself and you will find immense skyscrapers, residential buildings, condos and penthouses, standing firm for years in their own appealing beauty. Cement when mixed with collective, admixtures and water form an assorted mixture which is strong enough to withstand any weightiness. The requirement of high-quality concrete is indispensable for adequate métier development to hold the structure firmly. The quality of the cement confirms the strength of the concrete and the base of the construction of any building. Better the quality of the cement higher will be its ability to resist environmental degradation and protect the building from the vagaries of nature and other elements.

The quality of the cement should be checked before making the purchase by reading the manufacturing date and prescription of the time of use. You can easily check the quality by crumbling the cement in your hands and see if they form lumps in your hand. If they form lumps, then it’s an indication of excessive silt content.

Today, too the commonplace Portland cement, there are some other varieties of cement used by cement contractors in Brooklyn which warrant mention.

White: This cement conquers such a color since it is free from coloring oxides such as manganese, iron, and chromium and is mass-produced using oil. This cement is used for plastering, finishing, decorating such as marbles and glazed tiles.

Colored: Cement is usually given colors by partying stains with it. Chromium oxide make it green; cobalt makes it blue, and iron oxide makes it brown, red and yellow. This cement is hand-me-down to give colors to walls, floors and window sills.

Low Heat: This cement is used by cement contractors for enormous construction works such as dams and barriers. Low heat cement comprises 5% tricalcium aluminate and 46% dicalcium silicate which helps to keep the construction whole.

PORTLAND BLAST FURNACE CEMENT: In this situation, the normal cement clinkers are mixed with up to 65% of the blast furnace slag for the final oppressive. This type of cement can be used with benefit in mass concrete work such as dams, sidewalk repair, foundations, and abutments of bridges, retentive walls, construction in sea water.

WATERPROOF PORTLAND CEMENT: Water-resistant cement is prepared by mixing with normal or rapid acclimatization cement, a small percentage of some steel stearates (Ca, Al, etc.) at the time of grinding. This cement is castoff for the construction of water-retaining erection like tanks, reservoirs, retaining walls, swimming pools, dams, bridges, piers etc.

HYDROPHOBIC CEMENT: Hydrophobic cement is manufactured by adding water repellant chemicals to ordinary Portland cement in the process of grinding. Hence the cement stored does not decayed even during downpour. This cement is requested to remain unaffected when ecstatic during rains also. Hydrophobic cement is mostly used for the construction of water assemblies such dams, water tanks, spillways, water retaining structures etc.

HIGH ALUMINA CEMENT:  High alumina cement (HAC) is a special cement, manufactured by mixing of bauxite (aluminum ore) and lime at a certain temperature.  This type of cement is also known as calcium aluminum cement (CAC) we can we use for construction. The compressive strength of this cement is very high and more practical than normal Portland cement.

EXPANSIVE CEMENT: The cement which does not shrink throughout and after the time of hardening but increases slightly with time is called expansive cement. This type of cement is mainly used for grouting anchor bolts and prestressed concrete channels.

Quick setting: This type of cement is formed by adding a little aluminum sulfate and reduce the amount of gypsum. Since it is very finely grained, it starts settling within 5 mins and by half an hour it becomes hard.
