I ordered barrels of
pozzolana ash from Roman volcanoes and mimicked ancient recipes to manufacture hermae, four-sided pillars with the heads and phalli of Hermes.
They include
Pozzolana cement, bio lubricant, activated carbon, and bio fuel from local raw materials on a model scale, and would be translated eventually to a prototype scale in the recent future.
However, while BS EN 197- 1 [2] permits the use of silica fume (SF), metakaolin (MK, a natural calcined
pozzolana), fly ash (FA) and Ground Granulated Blast-furnace Slag (GGBS) of up to 10%, 35%, 55% and 95% respectively, data from the European Ready Mixed Concrete Organisation [3] showed that the total content of these supplementary cementitious materials (SCMs) in ready-mixed concrete, which are majorly FA and GGBS, is less than 20% of the total cement consumption.
The massive harbor project not only referenced Augustus; it was built using Roman construction techniques, including the use of hydraulic mortar that required the importation of massive amounts of volcanic
pozzolana from Italy.
It was commendation galore for NNBRRI, for its various research works and development over the years, which stakeholders said have culminated in the discovery and development of Interlocking Cement Stabilize Earthly Blocks (ICESEBs) and production of
Pozzolana cements.
Fly ash is a by-product from the residue of coal combustion, and it is a kind of
pozzolana. Fly ash tends to be spherical and micrometers to millimeters particles and has a relatively high reactivity depending on the chemical formation of its individual particle [1].
It is generally agreed that blended cements exhibit higher chloride binding ability due to higher amount of alumina and CSH phases that result from the incorporated
pozzolana.
Birla Corporation Limited is among the Top 10 cement manufacturers in the country, producing a full range of cement, including Portland
Pozzolana Cement (PPC), Portland Slag Cement (PSC), Ordinary Portland Cement (OPC) and Sulphate Resistant Portland Cement.
It can be used as a cement concrete aggregate by adding slag,
pozzolana, fly ash, lithium salts or by using low alkali cement.
The grinding plant has been designed to produce three different types of cement using clinker, gypsum,
pozzolana, limestone and fly ash.
