Local Contractors Laud New Cement
Import Allowance
By Rosli Abidin Yahya
Bandar Seri
Begawan - Local contractors expressed their gratitude to the
Government of His Majesty for allowing cement to be imported once
again into this country, a move that the contractors believe would
increase development activities brought about by cheaper prices of
the vital building component.
However, the local contractors felt
the allowable grade of 62.5 was relatively high and only required
for high rise buildings such as those found in countries such as
Singapore, Manila, Kuala Lumpur or even the big cities in China as
well as Hong Kong.
They said that in countries with
high rise buildings, cement grade 53 or 52.5 is the
normally-accepted standard.
They added a concrete structure is
built so as to last and give maintenance-free service for decades.
Accordingly, apart from strength,
long-term characteristics under service conditions and environmental
effects also become important considerations for performance.
"The major prescription for making
durable concrete is to achieve and ensure good quality control in
the production for concrete during construction, which is having the
right mixture of cement, sand, stone and water," they said.
In general, the comprehensive
strength of concrete for a given mix proportion increases with the
standard mortar strength of cement.
The contractors also said that the
Government move would bring about a reduction in prices, thereby
contributing to an increase in demand in the construction sector.
"The lower cost of construction
will induce more demand for construction and enable more people to
own houses as a result of lower cost of building construction," they
said. --
