Explanation:
Cement is a binding material that is used in construction work to bind aggregates like sand, gravel, and stones. It is made by heating limestone and clay at high temperatures. During the heating process, various compounds are formed that give cement its binding properties.
The most important compound in cement is calcium silicate. It is responsible for the strength and durability of the cement. There are two types of calcium silicate compounds found in cement: tricalcium silicate (C3S) and dicalcium silicate (C2S).
Tricalcium silicate (C3S) is the most important compound in cement. It is responsible for the early strength development of cement. It reacts with water to form calcium silicate hydrate (C-S-H) gel, which fills in the gaps between the aggregates and binds them together. The higher the percentage of tricalcium silicate in cement, the stronger and more durable it is.
Tricalcium aluminates (C3A) are also found in cement. They react with water to form calcium aluminate hydrates (C-A-H) and calcium hydroxide (Ca(OH)2). However, excess C3A can lead to quick setting of cement, which is not desirable in most cases.
Declaim silicate is not a compound found in cement. It is a term that does not exist in the context of cement chemistry.
Therefore, the correct answer is option 'A' - good quality cement contains a higher percentage of tricalcium silicate (C3S).
