The tires on an automobile are one of the most vital parts and are responsible for keeping drivers secure and safe. Though, tires are not cheap, nor are they necessarily eco-friendly. In fact, the energy of materials needed to manufacture tires costs tons of dollars and reasons damage to the atmosphere. In an effort be […]
The Ladle Covering Compounds which is widely applied in foundries and steel systems (plants) to eliminate the loss of heat liquid metal in the ladle. Since the temp of fluid metal is being poured into Moulds / dies / cavities is vital, this Ladle Covering Compounds decrease the temp of fluid metal in the ladle […]
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 […]
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 […]
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 […]
