Nigerian Building and Road Research Institute (NBRRI) Director-General, Prof. Samson Duna, has disclosed that the institution has come up with a cement technology, Pozzolana, which will reduce cost of cement and limit air pollution.
Pozzolana, a natural siliceous-aluminous material, reacts with calcium hydroxide in the presence of water at room temperature and is produced from agricultural and natural volcanic waste.
Prof. Samson Duna explained .that the cost of cement had increased drastically and that the production of pozzolana cement would reduce the dependence on conventional cement as well as cut down the price.
According to the Professor, cement production is associated with emission of gases into the atmosphere leading to pollution, and if the country ventured into pozzolana production, it would also greatly help in the reduction in gaseous pollution in the atmosphere and prices of cement as well.
“Once there is a shift in product, you will realize that the price will go down and you still get the product you want,” Duna said.
He further spoke of various technologies and interventions of the institute in collapsed buildings in Nigeria.
“When a building collapses, we go in to investigate. Our mandate does not give us power to arrest because we are a research institution.
“We carry out research and investigate what caused the problem, then create awareness so that the problem would not occur again,” he said.
The NBRRI Director-General said that, recently, the institute’s collaboration with Rotary Club was very beneficial to the Internally Displaced Persons (IDPs).
Speaking further, he recalled that the IDPs were taught how to mold blocks using the technology of pozzolana.
He said many of the IDPs in Abuja were taken to Jos where they were trained on the technology of pozzolana.
“We trained them on how to produce blocks and the blocks they produced were so fascinating because the technology is simple to understand.
“After that we gave them certificates. They were so happy and came back to tell us they wanted to construct their own buildings using the technology,” Duna said.
