Review on fly ash-based geopolymer concrete without portland cement
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper summarizes the factors that affect the properties of fly ash-based geopolymer concrete. Alkaline activator is an important material that controls the properties of geopolymer concrete. The workability of fresh ...
The tensile properties of chitosan filled polypropylene (PP) composites treated with acetic acid
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
The effect of chemical modification on tensile properties of chitosan filled polypropylene (PP) composites as a function of filler loading was investigated. The chemical modification was conducted via acetylation of chitosan ...
Effects of dynamic vulcanization on thermal properties of calcium carbonate filled polypropylene/ethylene propylene diene terpolymer composites
(Universiti Putra Malaysia Press, 2010-07)
In this study, dynamic vulcanization process was used to improve the thermal properties of calcium carbonate filled composites. The composites were prepared using a Z-blade mixer at 180°C and rotor speed 50rpm. Thermogravimetric ...

The effects of recycled acrylonitrile butadiene rubber content and maleic anhydride modified polypropylene (PPMAH) on the mixing, tensile properties, swelling percentage and morphology of polypropylene/recycled acrylonitrile butadiene rubber/rice husk powder (PP/NBRr/RHP) composites
(Taylor & Francis Group, 2010-09-13)
The effect of recycled acylonitrile butadiene rubber (NBRr) content and PPMAH as a compatibilizer on the properties of PP/NBRr/RHP composites were examined using a Haake Rheomix at 180°C, 60 rpm for 9 min. Results showed ...
