The behaviours of steel fiber as main reinfocement in high performance slurry infiltrated fiber reinforced concrete
Mustaqqim, Abdul Rahim; Zuhayr, Md Ghazaly; Ragunathan, Santiagoo; Shahiron, Shahidan (Trans Tech Publications, 2014)Normally, the concrete structure fabricated by combining steel bars as main reinforcement to the concrete mix. In this methid, the steel fiber is randomly distributed in the mould before the concrete slurry takes place. ... -
Comparison of processing and mechanical properties of polypropylene/recycled acrylonitrile butadiene rubber/rice husk powder composites modified with silane and acetic anhydride compound
Santiagoo, Ragunanthan; Hanafi, Ismail; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr. (SAGE Publications Ltd, 2014-12)Polypropylene (PP)/recycled acrylonitrile butadiene rubber (NBRr)/rice husk powder (RHP) composites were fabricated with silane and acetic anhydride (Ac) treatment agent.
