The other meaning of ³ASR² is ³alkali-silica reaction². This one can be good or bad, and in reality always happens. The construction professional only refers to the unwanted form of ASR when he talks about it, but the desired reaction between pozzolan and the lime from the cement-hardening process is also an ³ASR², though a much faster one.
Portland Pozolona Cement (PPC): PPC has 80% clinker, 15% pozolona and 5% gypsum and accounts for 18% of the total cement consumption. Pozolona has siliceous and aluminous materials that do not possess cementing properties but develop these properties in the presence of water.

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
2.2. Hydration of Portland cements. Cement requires clean water to hydrate effectively. The hydration process in concrete involves the cement compounds undergoing a chemical reaction with water to produce a stable, amorphous solid hydrate.
Advantages of PPC in Fresh Concrete Portland pozzolana cement (PPC) has following advantages when concrete is in its fresh state. 1. Workability Portland pozzolana cement has spherical cement particles and they have higher fineness value. Due to the spherical shape concrete move more freely and more fineness of particles allows better filling of the pores.
