This has made it the prominent concrete for development of huge number of solid and robust structures. Ordinary Portland cement, although the use of high-temperature curing can improve the early strength, the development of later strength will be affected. 0000016991 00000 n 0000032230 00000 n After several chemical reactions are produced, some spherical gray particles, what we called clinker, are formed. 7. … Therefore, the frost resistance of the three types of cement is poor. 0000006653 00000 n Portland Pozzolana Cement is becoming a popular type of cement used in building construction.PPC is made from pozzolanic material. The drying shrinkage of Portland pozzolana cement should not exceed 0.15%.The fineness of pozzolana cement should not less than 300m2 /kg. 0000024122 00000 n Successivamente il cemento pozzolanico , oltre che con pozzolana Good corrosion resistance. 0000042956 00000 n 0000007962 00000 n 0000023227 00000 n 0000015154 00000 n 0000029837 00000 n They are similar in nature and scope of application, so they can be used interchangeably in most cases. It is a kind of blended cement which is manufactured by mixing and fine-grinding silicate cement clinker, pozzolanic material, and gypsum. Pozzolana is a very old building material that was also used in Roman times. The material used in the manufacturing process is made of natural recycled waste. Portland Pozzolana cement is a type of low heat cement because it produces much less heat of hydration, it has better resistance to an aggressive water attack. 0000009146 00000 n Portland Pozzolana Cement (PPC) Portland Slag Cement (PSC) Gallery; Contact Us; Andhra Pradesh, India. The clinker content of the three kinds of cement is small, and the secondary hydration reaction is slow, while their later strength exceeds the ordinary Portland cement of the same grade. Pozzolanic material history extended up to roman time. 0000011185 00000 n PPC cement is available for decoration and artistic structures as its good surface finish. Un cemento pozzolanico contiene all'incirca: 45-89% di clinker Portland; 11-55% di pozzolana; 2-4% di gesso; Poiché la pozzolana reagisce con la calce (()), si avrà 0000032965 00000 n
