Cement | Properties | Uses |
Masonry cement | Inert materials like dolomite lime stones, gypsum, and air-entraining agent are mixed with clinkers of portland cement. Concrete is workable, and possesses, fattiness, cohesiveness, and plasticity. It contains mixing water then comes in contract with dry bricks. Not suitable for works other than masonry work. | Specially prepared for masonry work |
Oil well cement | It should capable of being pumped for 3 hours under high pressure and temperature, It sets slowly and hardens quickly. | Filling space between steel& liming and well of well |
Ordinary Portland cement | Fineness - Residue 10% when sieved on IS No 9 soundness -Expansion 10 mm, Compressive quickly3 days 160 kg/cm27 days 220 kg/cm2 setting time Initial 30 min Final10 hours | All types of ordinary construction works |
Pozzolanic cement | 20 to 40% pozzolana is mixed with 60 to 80% Portland cement while grinding. Volcanic ash, pumice, or powered burnt brick can be used as pozzolana. Produces less heat of hydration, resists sulfate action, develops strength slowly, imparts water tightness, more workability and plastically, possesses high strength and is cheap. | Mass concrete construction in coastal areas sewage works construction below ground |
Quick setting cement | Sets in 5 minutes and gets hard in 30 minutes. Fine grinding after adding a small percentage of aluminum sulfate. The percentage of gypsum and retarders are reduced. | Construction under running or stable water |
Rapid Hardening cement | High strength is achieved earlier due to a higher degree of fineness in grinding clinker at high temperature 7 days, and 28 days strength of ordinary concrete is obtained in 3 days and 7 days only Not suitable for mass concrete. | Concrete in cold weather climate, early removal of forms, speed in construction, early use of structure |
Sulphate resistant cement | The proportion of C3A is reduced and C2S is increased. Hardness is slow, a longer period of curing. | Culverts, canal siphon canal lining in alkaline soil |
Super Sulphate cement | 80 to 85% well granulated slag is mixed with 10 to 15% calcium sulfate and 1 to 2% Portland cement. Mir is finely ground. Low heat of hydration, hence suitable for mass concrete. lt should NOT be mixed with ordinary Portland cement or High alumina cement. Resistive to chemical attack, cement expands when used underwater and shrinks when cured in air. Forms a good bond with set concrete. | Suitable for all-purpose mass concrete places where a chemical attack is suspected. |
Water Proof Cement | Calcium stearate. Aluminum stearate and gypsum-treated tannic acid are added to ordinary Portland cement while grinding. Resistive to water penetration Resistive to corrosive action of acid and alkalies. | Tanks, reservoirs drams, bridge piers swimming pools |
White cement | The percentage of Iron Oxide was reduced to 1% to avoid greyish colour oil is used as fuel. Chalks and limestones having low iron content and white clay are used as raw materials strength less than ordinary concrete. High cosot | Production of light coloured cement floor finish, plaster work, ornamental works, and precast concrete blocks |
Acid Resistance cement | Quartz Quartzites are used as aggregates + Soluble glass for increasing resistance against acid and to act as binding material. | Chemical industries, Acid resistant, Heat resistant |
Air entraining Cement | Air entraining against - oils, fatty acids, dorex resin mixed during during grinding. Strength reduced lay 10 to 15%, workable, plastic, resists froest action. | Concrete roads in cold regions frost resistance |
Blast furnace slag cement | Granulated blast furnace slag mixed while grinding workable plastic, resistive to dampness, sulfate action, corrosive effect less heat of hydration economical not suitable for cold weather. | Prefabricated RCC units Alkaline soil, mass, concrete marine works underground works. |
Coloured cement | Raw materials - china clay, pure lime. White cement is used to light color | Floor finish artificial marble stair treads window sills. |
Expanding cement | Sulphate Aluminates and stabilizing agents are added to ordinary cement. This cement expands while hardening. | Water retaining structures problems of leakages requirements |
High Aluminum cement | Obtained by calcinating lime stone and Bauxite. Resists chemical effect high temperature, corrosive action on acid, and seawater, evolves head during setting. Higher initial setting time and lower final setting time. Compressive strength double than of ordinary cement, should not come in contact with lime or ordinary cement. | Frost regions, seawater, refractory and heat resistant. Concrete concreting against internal water flow, high early strength. |
Extra Rapid hardening cement | 20% calcium chloride ground with Rapid hardening cement, strength - 25% higher then Rapid harding more shrinkages | When very high early strength is required, cold weather concreting and Early removal of Form work. |
High-strength ordinary cement | Higher Compressive strength | Pre-cast and pre-stressed units. Indian railways. |
Hydrophobic cement | Obtained by grinding naptha, acidol, and soap with cement clinkers formation of thin films on grains of concrete can be stored for longer periods. | Cold and frost-forming weather. |
Low Heat cement | Percentages of C3A and C3S are reduced and C2S and C4AF are increased. Less compressive strength. Greater sulphate resistance.Delay in construction speed not suitable for ordinary works. | Mass concrete works resistant to sulfate action. |
