Class C well cement can be a basic intent hydraulic oil well cement for various petroleum well purposes and is particularly suitable to be used at depths of as much as 6,000 ft when circumstances call for high early-toughness and average sulfate resistance.

Concrete is robust in compression, as the aggregate effectively carries the compression load. However, it's weak in pressure given that the cement holding the aggregate set up can crack, allowing for the composition to fail.

The concrete solidifies and hardens through a chemical method named hydration. The water reacts With all the cement, which bonds one other parts collectively, making a strong stone-like material.

The combo design will depend on the sort of construction currently being built, how the concrete is blended and shipped, and how it's put to kind the construction.

the fine-grained materials that binds jointly the much larger constituents in many sorts of sedimentary or clastic rock

Combining water which has a cementitious content forms a cement paste by the entire process of hydration. The cement paste glues the aggregate jointly, fills voids in just it, and makes it circulation much more freely.[24]
