AS you read this piece, the Technical Committee set up by Standards Organisation of Nigeria (SON) is reviewing the Nigeria Industrial Standards -NIS 444- 1: 2014 cement standard.
They would soon submit the new guideline to SON Council for vetting, approval and implementation.
The Technical Committee is headed by Joseph Odigure, of Council for the Regulation of Engineering in Nigeria (COREN) at the University of Lagos, and Professor Garuba Abu as Vice Chairman.
Osita Aboloma, Director-General, SON, said that the standard is being reviewed for the next five years.
“The exercise is imperative as standards can be reviewed after five years or at any time at the instance of the stakeholders or if found inadequate due to changes in technology, test methods and government policies.”
“The proposed standard will help to monitor the quality of cement in Nigeria as well as checkmate the menace of the incessant collapse of buildings and concrete structures as a result of poor cement quality and application.”
“Cement standard is no doubt a very important one, as about 80 percent or more of the buildings and other infrastructural development of any nation, and indeed Nigeria is carried out with the use of cement.
“Cement is a binder for all the components of the building and its poor application in the construction has been blamed for failures and collapse in the building and construction industry.
He urged the technical Committee to use their wealth of knowledge and experience to bear in ensuring global best practices in the final draft of the standard to be submitted to the Standards Council for consideration and approval.
According to him, the proposed standard will help to monitor the quality of cement in Nigeria as well as checkmate the menace of the incessant collapse of buildings and concrete structures as a result of poor cement quality and application.
Nigeria Industrial Digest learned that the existing cement standard restricts the use of the 32.5 grade strength to plastering of structures only; while the 42.5 grade is for the construction of buildings, beams, load-bearing columns, pillars, block molding and other structures; and the 52.5 is for bigger projects like bridges, flyovers and high rise buildings.
