Cement, though dissimilar from the sophisticated product found nowadays, has been used in a lot of forms since the start of human civilization. From volcanic ashes, crushed pottery, burnt gypsum and hydrated lime to the first hydraulic cement applied by the Romans in the middle ages, the growth of cement sustained to the 18th century, when James Parker patented Roman cement, which achieved fame but was replaced by Portland cement in the 1850s.
Rosendale cement was discovered in 19th century in New York. Although its rigidity made it pretty popular at first, the market require soon refused because of its long curative time and Portland cement was again the favorite.
Function of Cement
1. to combine the sand and coarse collective together
2. to fill annulled in between sand and coarse aggregate element
3. to form a compress mass


Types of Cement
There are 2 types of cement normally used in building industry are as follows:
1. Hydraulic Cement
2. Nonhydraulic Cement
Hydraulic Cement
Most commonly used cement nowadays is a hydraulic cement known as Portland cement or Portland cement blends. These are generally the basic element in making concrete, which is a building material used as a load-bearing element. Portland cement is appropriate for wet ambiances and can be used underwater. Different types or blends of Portland cement comprise Portland blast furnace slag cement.
In other words it means that hydraulic cement is:
“Any cements that spins into a hard product in the existence of water ensuing in a material that does not fall to pieces in water.”
Cement Chemistry of Hydraulic Cement
On the other hand, hydraulic cement is mostly ended up of silicates and oxides:
1. Belite (2CaO•SiO2);
2. Alite (3CaO•SiO2);
3. Tricalcium aluminate/ Celite (3CaO•Al2O3)
4. Brownmillerite (4CaO•Al2O3•Fe2O3)
Non-hydraulic Cement
Any cement that does not need water to renovate it into a solid product.
Cement Chemistry of Non-hydraulic Cement
Non-hydraulic cement is formed all the way through the following steps:
1. Calcination: Lime is formed as of limestone at over 825°C for about 10 hours. (CaCO3 → CaO + CO2)
2. Slaking: Calcium oxide is varied with water to create slaked lime. (CaO + H2O → Ca(OH)2)
3. Setting: Water is absolutely dispersed.
4. The cement is uncovered to dry air and it hardens later than time-consuming reactions. (Ca(OH)2 + CO2 → CaCO3 + H2O)
Uses of Cement
The applications of cement over a variety of fields of construction have completed it a very important civil engineering material.
Some of the various functions of cement are given below.
1. It is used for assembly combines for drains and pipes.
2. It is used for water stiffness of structure.
3. It is used in concrete for put downs floors, roofs and constructing lintels, beams, stairs, pillars etc.
4. It is used where a hard facade is compulsory for the protection of covered surfaces of structures next to the unhelpful agents of the weather and certain organic or inorganic chemicals.
5. It is used for precast pipes developed, piles, fencing posts etc.
6. It is used in the building of significant engineering structures such as bridges, culverts, tunnels, lighthouses etc.
7. It is used in the preparation of foundation watertight floors, footpaths etc.
