14 Types of Cement And Their Practical Uses in Concrete Construction
Hello guys here i have explain all 14 types of cement with their actual practical uses. I hope you like this , article read it completely. I also mention Indian standard code (IS code) of various cement type.
- Ordinary Portland Cement (OPC)
- Rapid Hardening Cement
- Quick Setting Cement
- Low Heat Cement
- Sulfates Resisting Cement
- Portland Pozzolana Cement (PPC)
- High Alumina Cement
- Hydrographic Cement
- High strength Portland Cement
- Blast Furnace Slag Cement
- Expansive Cement
- Masonry Cement
- White Cement
- Water Proof Cement
(1) Ordinary Portland cement (0.P.C.) (IS: 269 – 1989):
- Used in all types of construction in areas where sea and salinity are not high.
- About 60% of the cement used in the India is Portland Cement.
(2) Rapid Hardening Cement (R.H.C.) (IS: 8041 – 1990):
- It has high C3S and low C2s.
- Hydration is faster and produces more heat.
- The strength obtained from this cement is obtained in just 3 days same as 7 days strength of Ordinary Portland cement thus get faster strength .
- Producing more heat which cannot be used in concrete.
- Where to remove formwork fast
- Road repair word
- In cold weather
- Prefabricated units
(3) Quick Setting Cement :
- Quick setting of cement is done but strength does not get quickly.
- Aluminium sulphate is added
- For early setting time Gypsum is added.
- Under water construction
- For Grouting
(4) Low Heat Cement (IS: 12600 – 1989):
- Proportion of C3S, C3A Low.
- High C2S.
- Low hydration rate and low heat production.
- Mass Concrete (dam)
- To produce resistance to sulphate attack (Since C2A is low)
- For hot weather.
(5) Sulphate Resisting Cement (Is: 12330 – 1988):
- C3A levels are kept very low (about 5%).
- Magnesium sulphate is react with the free Calcium Hydroxide in cement to form calcium sulphate and by combining with Calcium Aluminate to form Calcium sulphoaluminate , So that the expansion and disintegration of concrete takes place.
- Marine Conditions
- Sewage Treatment Plant
- For RCC Pipes
- For bases and basements in silt and muddy soils
- For construction of chemical industry
(6)Portland Pozzolana Cement (IS: 1489 – 1991, Part – I):
- This cement is made by adding powder to OPC. Or, it is made by grinding with Portland cement clinker, pozzolana and gypsum.
- Natural Pozzolana → clay, shale, pumicites, volcanic ash
- Artificial Pozzolana → Fly ash, surkhi
- Mass concrete.
- For seawater construction .
- Hydraulic construction.
(7) High Alumina Cement (IS: 6452 – 1989):
- 40% bauxite
- 40% lime,
- 15% iron oxide
- 75% silica and magnesia
- 80% strength In 24 Hour.
- Rapid hardening quality.
- For construction in seawater (due to chemical resistance)
- As Refractory Concrete which can withstand temperature of 1600 ° C.
(8) Hydrophobic Cement (IS: 8043 – 1991):
- Stearic acid, Oleic acid, Boric acid are added during OPT clinker grinding.
- This acid forms a layer around the cement particles which protects the cement from moisture in the air.
- Thus cement can be stored for a long time without the effect of moisture.
(9) High Strength Portland Cement (IS: 8112 – 1989):
- High Strength
- High C2S
- High fineness of 3500 cm/gm.
- Prestress Concrete
- Precast Concrete
- Air Field works
(10) Blast furnace slag cement (IS: 455 – 1989):
- Made by grading of OPC clicker, gypsum and blast furnace slag (waste in the production of pig).
- It produces low heat of hydration so cannot be used in cold region.
- Useful in Mass Concrete.
- Used for construction in seawater.
(11) Expansive Cement:
- This cement is made by grinding OPC clinker, alumina cement, gypsum etc.
- The cement shrinks during the concrete setting process.
- War Timely repair works
- Shrinkage prevention
- Cement stabilization
- Emergency works
(12) Masonary Cement (IS: 3466 – 1988):
- Grinding inert materials such as limestone, dolomite gypsum, dolomite limestone and air-intended plasticizer with OPC clicker into the appropriate mixture.
- Can be used in place of lime motor, cement mortar, lime-cement mortar.
- Defects found in OPC such as compression cracks, vertebral defects, plastic mixes, etc. can be removed with this cement.
- Used extensively in constructions where low strength is required.
(13) White Cement (Is: 8042 – 1989):
The gray colour of cement does not come due to low iron oxide content while making cement. Using oil as fuel instead of coal in the kiln when making cement does not cause impurities in the cement and gives the color white.
- Flooring like glaze tiles and mosaic tiles.
- Aesthetic view.
(14) Water Proof Cement:
- This cement is made by adding gypsum prepared in waterproof substances like calcium stearate, aluminum stearate and tannic acid.
- This cement is used to reduce the permeability of concrete.
