• Silica from rice husk ash

    New research has shown that rice husk ash (RHA), an agricultural waste product, could be used to synthesize nanosized hydroxy-sodalite (HS) particles, a type of zeolite. HS particles are a rich source of silica, which is an essential material for fabricating semiconductor devices. Rice husk is an abundantly available agricultural waste material that contains a […]

  • Benefits of Use of Rice Husk Ash in Concrete

    In this investigation, a feasibility study is made to use Rice Husk Ash as an admixture to an already replaced Cement with fly ash (Portland Pozzolana Cement) in Concrete, and an attempt has been made to investigate the strength parameters of concrete (Compressive and Flexural). For normal concrete, Indian Standard (IS) method of mix design […]

  • Effect of Rice Husk Ash on Cement Mortar and Concrete

    Work-ability, strength, and durability are three basics properties of concrete. Amount of useful internal work necessary to overcome the internal friction to produce full compaction is termed as Work-ability. Size, shape, surface texture and grading of aggregates, water-cement ratio, use of admixtures and mix proportion are important factors affecting work-ability. Strength is to bear the […]
