cement board from paddy straw

Mechanical and physical properties of natural fiber cement board for

25 Aug 2014 to ensure the satisfactory performance of fiber cement materials, improved understanding of their expected long- term performance is essential (Bledzki and Gassan,. 1999). The use and processing of rice straw in the manufacture of cement-bonded fiberboard were evaluated by group of researchers (Fernandez and Taja- on, 2000). Strength and dimensional properties of cement bonded wastepaper and sawdust composite boards were evaluated by Osuntuyi (2002). 【Get Price】

10 May 2014 WOOD RESEARCH for example, combination use of Na2SiO3 and CaCl2 was found to confer better strength to the rice straw-cement board than the chemical additives used singly (Fernandez and Taja-on 2000). Some mineral additives added to a mixture of cement and wood improve its quality. According to Sellevold and Nilsen (1987), one of the most promising additives for the wood- cement boards industry is silica fume. The rapid growth of the silica fume use in  【Get Price】

properties of gypsum construction material modified with rice straw

Global warming enforces researchers to reduce revival of CO 2. Reuse of rice straw instead of its burning and reduction of consumption of Portland cement are two major factors in the way of reducing the global warming. Gypsum as eco-friendly binder material can replace Portland cement in multi applications. Plastering, gypsum boards and gypsum blocks are examples for using gypsum as a binder material. Consuming natural fibers in Portland cement based binder material usually  【Get Price】


27 Sep 2008 Rice is the staple food of a majority of Indians, and the annual rice harvest generates a large amount of waste. Mostly in the form of rice-husk, amounting to nearly 20 million tonnes in a year. A manufacturer in Bangalore is now producing particle boards from this rice-husk. These boards can be used to replace timber in construction. Thus helping in conserving forests, while finding a resourceful use for waste. 【Get Price】

Use of Rice Straw Ash as Pozzolanic Material in Cement Mortar - IJET

Abstract—In this paper an experimental study was made on the effects of using Rice straw Ash (RSA) as a partial replacement of cement in mortar. Control specimens with ordinary Portland cement (OPC) was made and in other specimens cement were replaced with 5%, 10% and 15% of. RSA by weight of cement. Locally available rice straw was burnt to ash in uncontrolled manner in the earthen oven used by the rural people for cooking purpose, which were used in this study. 【Get Price】

Developments in Cement-Bonded Composite - ResearchGate

Nevertheless, using accelerated processing techniques based on carbonation reactions cement- wheat straw boards were successfully made. Using combination of pre-treatment and accelerators cement-bonded boards are also made using coir, bagasse and arhar stalks. These boards meet the minimum standard mechanical, durability and physical requirements. However, the cement bonded rice straw boards made by Fernandez and Taja-on [22] using two cement: rice-straw ratios  【Get Price】

Manufacture of High-Performance Rice-Straw Fiberboards

14 Dec 2009 Rice straw, a waste agriculture material grown and harvested in Willows, CA, was used as a material in the production of thin medium- and high-density fiberboards (MDFs and HDFs). The rice The water-repelling properties of the 3-mm rice-straw fiberboards were encouraging; the thickness swelling (TS) was in the range of 15?30%.
