The results showed that a pozzolanic reaction is already taking place during early hydration, depending on the mineralogical composition of the calcined clays. Calcined clays compete with cement clinker for available ions (especially sulfate and carbonate ions) in the pore solution.

In order to reduce energy consumption and CO2 emission, and increase production, cement manufacturers are blending or inter-grinding mineral additives such as slag, natural pozzolana, and limestone. This paper reports on the results of an experimental study on the production of self-compacting concrete (SCC) produced with …

Pozzolana, hydraulic cement, perfected by the Romans and still used in some countries, made by grinding a material of volcanic origin with powdered hydrated lime. The material contributed to the evolution of new architectural forms in such monumental constructions as the Pantheon and the Baths of Caracalla.

Portland pozzolana cement (PPC) is used for the construction of houses, schools, and residential building slabs. PPC is cheaper than ordinary Portland cement. What Is Pozzolana Cement? Pozzolanic cements are mixtures of portland cement and a pozzolanic material that may be either natural or artificial. The natural pozzolanas are …

A final benefit of cement–pozzolana blends exposed to chloride solutions is the reduced portlandite content. Cement samples exposed to sodium chloride solutions show increased evidence of portlandite leaching. The pozzolanic reaction reduces the availability of portlandite, thus reducing calcium leaching and improving durability. ...

Since the pozzolanic material reacts with calcium hydroxide liberated by the hydrating Portland cement and forms cementatious compounds, PPC makes the concrete more impermeable and denser. It can be confidently employed in construction of hydraulic structures, marine works, mass concreting etc. It protects concrete against alkali …

Sugar cane bagasse ash (SCBA) is generated as a combustion by-product from boilers of sugar and alcohol factories. Composed mainly of silica, this by-product can be used as a mineral admixture in mortar and concrete. Several studies have shown that the use of SCBA as partial Portland cement replacement can improve some properties …

Portland Pozzolana Cement Manufacturing Process. Just like the manufacturing process of ordinary portland cement (OPC), the portland pozzolana cement manufacturing process includes five main steps: raw material treatment, preheating and pre-homogenization, calcining and burning, cement clinker grinding, and packaging and storage.
