Strength Properties Of Hybrid Nylon-Steel And Polypropylene-Steel Fibre-Reinforced High Strength Concrete At Low Volume Fraction, Hilmi Mahmud
Hilmi Mahmud
The strength properties of hybrid nylon-steel fibre-reinforced concrete were investigated in comparison to that of polypropylene-steel fibre-reinforced concrete, at the same volume fraction (0.5%). The content of the high performance macro structure steel fibres is at 0.4% volume fraction, and the content of micro nylon and polypropylene-fibres is at 0.1% volume fraction. The experimental results show that the compressive strength and splitting tensile strengths and modulus of rupture (MOR) properties of the nylon-steel fibre concrete improved by 3.2, 8.3 and 10.2%, respectively, over those of the polypropylene-steel fibre concrete. On the impact resistance, the first-crack and failure strengths, and the …
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.
