Which cement is best for footings?

Which type of cement is best for constructing the foundation? The foundation carries the load of the construction and hence needs to be strong and durable. Portland Pozzolana Cement (PPC) is the ideal cement to be used as it hydrates slowly and gives high final strength.

Does concrete need air cure?

The most crucial time for strength gain of concrete is immediately following placement. In field conditions, heat and wind can dry out the moisture from the placed mixture. Concrete that is allowed to dry in air will gain only 50% of the strength of continuously moist-cured concrete.

Should I use cement or concrete?

Concrete works well in larger projects, while cement is more often used in smaller jobs. One of the strongest and longest-lasting materials known to man, concrete is used to build schools, bridges, sidewalks, and countless other structures.

How do I keep my concrete from hardening?

Things to remember:

  1. Keep cement protected from dampness and moisture.
  2. Do not place cement bags directly on concrete or wood floors.
  3. Handle cement bags carefully.
  4. Keep cement bags protected during transportation.
  5. Store cement bags separately.
  6. Provide adequate ventilation when stored in pallets in warehouses.

How long does concrete take to set?

After concrete is placed, the concrete increases in strength very quickly for a period of 3-7 days. Concrete which is moist cured for 7 days is about 50% stronger than uncured concrete. Water curing can be done after the slab pour by building dams with soil around the house and flooding the slab.
