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 […]
This paper presents a study on the development of compressive strength up to 91 days of concretes with rice-husk ash (RHA), in which residual RHA from a rice paddy milling industry in Uruguay and RHA produced by controlled incineration from the USA were used for comparison. Two different replacement percentages of cement by RHA, 10% […]
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 […]
Global Rice Husk Ash Market: Overview Rice Husk Ash (RHA) is a product obtained by burning rice husk, which is the outer covering of rice harvested from a paddy field. Rice husk is used to generate renewable energy. The RHA obtained from rice husk is as valuable as the rice husk in numerous applications. However, […]
Special to The Digest At 758.8 million tonnes (503.6 million tonnes, milled basis), world paddy production in 2017 would stand 0.8 percent, or 5.8 million tons, above a revised estimate for 2016. The comparatively modest year-on-year increase mirrors constraints posed by tight margins and heightened competition with other crops, could entail a slow-down in the […]
