It sets, fortifies, and adheres to other materials to bind them together. Cement is majorly used in its original form, but sometimes it is also used to bind sand
The lime deposit was found near the site for the factory at Runhengeri. The production cost of lime pozzolana, as reported by Adepegba (1990) was about RwF6000 (RwF100 US$1) per tonne, whereas the production cost of Portland cement was about RwF30,000 per tonne the lime- pozzolana cement costs about one fifth the cost of Portland cement.
Through laboratory trials, BRRI has successfully produced Pozzolana cement from bauxite waste and clay, which could be found almost in every district of the country. And the Pozzolana cement is selling at 25, 000 cedis for the same 50kg bag. The production process for the pozzolana cement is simple.
such as Central Africa, Central America and Indonesia there are enormous deposits of volcanic ash. In India and other Asian countries rice husk ash (RHA), (the husks can often be difficult to dispose of), provides a good source of pozzolana for use in masonry cements.
Advantages of Portland Pozzolana Cement. it is an eco-friendly cement as the material used in the manufacture are made of natural recycled waste. It is very fine cement hence very good when used for plastering works. Pozzolano consists of silica material which makes it cheap and hence reduces the cost of the cement making it economical to use.
The lowering of the blended cement environmental cost associated with the greenhouse gases emitted during Portland cement production. A third advantage is the increased durability of the end product. Renelux sources volcanic based Pozzolana from North Kalimantan, Indonesia for destinations in Middle East and not only.
Pozzolana, also spelled pozzuolana, or pozzolan, hydraulic cement discovered by the Romans and still used in some countries, made by grinding pozzolana (a type of slag that may be either naturali.e., volcanicor artificial, from a blast furnace) with powdered hydrated lime.Roman engineers used two parts by weight of pozzolana mixed with one part of lime to give strength to mortar and ...
