Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass.

What Is Cement Made Out Of?
But cement isn’t some sort of naturally occurring organic material – it’s manufactured through the chemical combination of 8 main ingredients during the cement production process. These ingredients are generally extracted from limestone, clay, marl, shale, chalk, sand, bauxite, and iron ore.
What Are Types Of Cement?
- Ordinary Portland Cement (OPC)
- Portland Pozzolana Cement (PPC)
- Rapid Hardening Cement.
- Extra Rapid Hardening Cement.
- Low Heat Cement.
- Sulfates Resisting Cement.
- Quick Setting Cement.
- Blast Furnace Slag Cement.
What Is Cement Formula?
4CaO·Al2O3·Fe2O3 = calcium alumino ferrite. C-S-H. Calcium silicate hydrate, a colloidal and mostly amorphous gel with a variable composition; this is the major hydration product of Portland cement, constituting approximately 70 percent of the paste, and is the phase providing most of the strength and binding.
What Are The Main Properties Of Concrete?
- Mechanical strength, in particular compressive strength. The strength of normal concrete varies between 25 and 40 MPa.
- Durability.
- Porosity and density.
- Fire resistance.
- Thermal and acoustic insulation properties.
- Impact resistance.
What Are Properties Of Cement?
- Fineness of cement.
- Soundness.
- Consistency.
- Strength.
- Setting time.
- Heat of hydration.
- Loss of ignition.
- Bulk density.
Which Grade Of Cement Is Best?
OPC 53 grade cement has better quality, strength, and less setting time compared to 33 and 43 grades of cement. Due to its high strength, is used for making concrete of higher grade (Above M20). It is the best choice for all houses, buildings, apartments, and high-rise building construction work.
What Are The Advantages And Disadvantages Of Cement?
| Advantages of concrete | Disadvantages of concrete |
|---|---|
| It possesses high compressive strength to withstand a huge amount of load. | It has low tensile strength and hence cracks are developed. |
