When the three types of cement are cured at high temperatures, the hydration of the active mixture and clinker will be accelerated, and the early strength is improved without affecting the development of the later strength. Portland pozzolana cement improves pore size distribution and also reduces the micro cracks in the cement paste at the transition zone due to pozzolanic action and being finer than OPC. 0000025554 00000 n
Portland pozzolana cement is now gaining acceptance in General Constructional works and also some types of special concrete applications. It has low hydration heat, good corrosion resistance, impermeability, and frost resistance. Portland pozzolana cement is suitable for concrete works underground, in water, or humid environment, especially for projects requiring impermeability, freshwater resistance, and sulfate corrosion resistance, such as hydraulic structures, marine structures, dam construction, construction near the seashore, sewage disposal construction, etc. trailer
