An Innovative Concrete Practice Performance Measurement Towards Environmental Improvement In Malaysia, Hilmi Mahmud
An Innovative Concrete Practice Performance Measurement Towards Environmental Improvement In Malaysia, Hilmi Mahmud
Hilmi Mahmud
The environmental impact from the concrete construction industry is quite alarming. The industry is embarking into improving the concrete performance and exploring into alternative materials to reduce such impact. An area which is lacking is improvement in the quality of concrete practice itself. By having good concrete practice, a good quality concrete can be achieved. This paper proposed a performance measurement of concrete practice and applies the measurement to assess the quality of concrete practice for a concrete structure project in Malaysia. © 2010 IEEE.
Development Of Lightweight Concrete Using Industrial Waste Material, Palm Kernel Shell As Lightweight Aggregate And Its Properties, Hilmi Mahmud
Hilmi Mahmud
Agricultural industrial wastes produced after extracting palm oil from palm fruits known as palm kernel shell (PKS) are available in large quantities in Indonesia, Malaysia, Nigeria and other tropical countries. Malaysia is the second largest palm oil producing country in the world. This paper reports the results of an investigation conducted to utilize the PKS as lightweight aggregate to produce grade30 concrete with density of about 1850kg/m 3. The properties of both PKS and crushed granite aggregates were compared. The concrete produced using PKS referred to here after as palm kernel shell concrete (PKSC) and its properties were compared with …
