Technical Marketing Executive Interview Questions and Answers

The specific gravity of cement is a measure of its density compared to the density of water.

• Specific gravity of cement typically ranges from 3.1 to 3.16.

• It is an important property that helps in determining the quality and strength of cement.

• Specific gravity is determined by comparing the weight of a given volume of cement to the weight of an equal volume of water.

• Higher specific gravity indicates higher density and better quality of cement.

• For example, if the specific gravit...read more

Bogues compounds are impurities in cement that affect its quality and strength.

• Bogues compounds include tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite.

• The presence and amount of these compounds can affect the setting time, strength, and durability of cement.

• Controlling the amount of bogues compounds is important in ensuring the quality of cement.

• Bogues compounds are named after the French chemist Léon Le Chatelier, who first ide...read more

The density of RCC (Reinforced Cement Concrete) varies depending on the mix design and ingredients used.

• The density of RCC typically ranges from 2200 to 2500 kilograms per cubic meter (kg/m³).

• The density can be influenced by factors such as the type and proportion of aggregates, cement content, water-cement ratio, and air content.

• Higher density RCC is often used in structural elements like columns and beams to provide strength and durability.

• Lower density RCC may be used in n...read more
