Question

A cement paste prepared with 300 gm of cement has a water cement ratio (W/C) pf 0.4, what is the capillary porosity at the end of one year assuming that maximum hydration has taken place.

Answer 1

At the end of the year, the value of capillary porosity will be 0.36 after maximum hydration

Explanation:

• A correct ratio of cement and water is necessary to make a smooth homogeneous paste.
• The loss of water due to evaporation ned s to be fixed during the setting time.
• Therefore the correct capillary porosity is the actual water and the cement ratio is the mixture.
• At the end of the year, the value of capillary porosity will be 0.36 after maximum hydration.
