PPC cement slightly prolongs the setting time of concrete which helps the mason for good finishing of concrete or cement mortar. The cohesiveness of concrete mix helps for better finishing of concrete.
Proportioning Concrete Typical mixing procedure: 1. Clean mixer 2. Add aggregates and mix for 2 minutes 3. Add cement and mix for 2 minutes 4. Add ½ of the mixing water and mix for 2 minutes
Portland Cement: Fine powder of mixture of Calcium Silicate Calcium Aluminate of varying composition which on hydration (By adding Water Drying) forms rigid structure having good compressive strength known as Portland Cement
The measurement of chemical composition is the oldest and still the most important means of characterising cement materials and controlling the manufacturing process. However, analysis to a high degree of precision and accuracy is a relatively modern practice, and even today is often lacking.
