2. What is cement?
Cement is a powder-like substance that serves as a binding agent in
construction materials and provides strength and durability to
structures. It is formed by heating a mixture of raw materials, usually
limestone and clay, at high temperatures in a kiln. The chemical
reaction which ensues turns the raw materials into clinker, which is
finely ground to produce cement.

52. Different types of cement you must know

53. Cement is primarily characterized into two types:-
1. Hydraulic cement
2. Non-hydraulic cement.
Hydraulic cement:
The cement which hardens in the presence of water because of
Hydration (The chemical reaction between cement and water).
This type of cement can also harden in underwater. Portland
cement is the best example for hydraulic cement.
Non Hydraulic cement:
The cement which doesn’t harden underwater is called non-
hydraulic cement. This type of cement hardens when it reacts with
the atmospheric carbon dioxide (carbonation). This cement is
resistant to attack by chemicals after setting. Non-hydraulic
cement is manufactured using non-hydraulic lime, gypsum
plasters and oxychloride, which has liquid properties.

55. OPC Vs. PPC Cement: What is Best For Your Project?
● Choosing the right cement is crucial for your home’s
strength and durability.
● OPC is ideal for quick setting and early strength,
while PPC is better for long-term durability and
resistance to environmental factors.
● Remember, once you decide on your cement, it can’t
be replaced, so choose the one that best fits your
project’s needs.
● If you’re asking which cement is the best OPC or
PPC, it depends on whether your priority is early
strength or long-term durability.
What are Type 1 and Type 2 cement? Acc to ASTM description
Type 1 cement refers to Ordinary Portland Cement (OPC) and
Type 2 cement typically refers to Portland Pozzolana Cement (PPC).
