roof tile made from rice husk and polymere

A Thesis Submitted to - Ethesisnitr - NIT Rourkela

The annual rice husk production in India amounts is generally approximately 12 million tons. rice husk is generally not recommended as cattle feed since cellulose and other sugar contents are low. Worldwide production of rice husk is about This is a relatively small operation, but there is potential to increase this market. It is thought it is amorphous ash that is being used [24]. There are other uses for RH which are still in the research stages [21]:. • In the manufacture of roof tiles.

If a long term sustainable market and price for rice husk ash (RHA) can be established, then the in the manufacture of roof tiles. • as a free running agent for fire extinguishing powder. • an abrasive filler for tooth paste. • a component of fire proof material and insulation. • as a beer clarifier. • extender filler for paint. • production of

The present requirement of wood in India is about 29 million cubic meters, where as, the estimated production is about 16 million cubic meters only. Apart from wood, natural fiber composites are emerging with an increasing role in building industry to replace timber, steel, aluminum, 


The result of the study revealed that rice husk can be used to replace asbestos, in the production of corrugated roofing sheets. Also the usage of industrial wastes still needs study on their better usage toxicity. These materials if studied and developed properly hold the key to address the current housing needs. The roofing tiles can be adapted particularly for hot climate due to its high insulation properties and therefore suitable to provide shelter for livestock by using the locally 

5Rice Hulls for Composites - Smithers Rapra

rice is the staple diet of many people all over the world. More than 100 million metric tonnes of rice are produced annually, especially in Asia and the Far East. rice hulls are the protective coatings of the rice seeds or grains. These hulls are formed by a hard material and are unique products of nature. They contain ≈20% opaline silica in combination with a large amount of structural polymer called lignin. These hard coatings protect the rice seeds during the growing season until

Properties of Rice Husk Ash Stabilized Laterite Roof Tiles

This paper presents the results of work on the possibility of using of rice husk Ash (RHA) in the production of clay roof tiles. The pozzolana content of the ash was determined using X-Ray Fluorescence (XRF) to confirm the key elements of RHA as a good pozzolanic material. The tiles were produced by moulding clay-RHA blends of various proportions of RHA used in wooden moulds. The percentages by weight of RHA added to various mixes were 0, 5, 10, 15, 20, 25 and 30% RHA

The rice Hull House. By Paul A. Olivier, Ph.D. ABSTRACT. The rice hulls are unique within nature. They contain approximately 20% opaline silica in combination with a large amount of the phenyl propanoid structural polymer called lignin. can be labeled and marketed as proprietary. Perhaps the humble use of the rice hull as an insulation material does not sufficiently inspire the scientific or commercial imagination. But why focus on man-made products when natural materials 


Finally I appreciate every other Civil Engineering students that I have sat and learnt with, in the same class. v ABSTRACT This research deals with the effects of using rice husk ash (RHA) as a partial weight of cement replacement in concrete roof tile production. The work is based on an experimental study of roof tiles produced with ordinary Portland cement (OPC) and 5 %, 10 %, 15 % , 20 % and 25 % (OPC) replaced by RHA. The rice husk ash used was produced by open air burning 

Environmentally Friendly Roofing Materials in Chiang Mai

combining rice husks, which have a high content of silica, with high-density polyethylene, scientists have been able to create a bio-composite that is water-resistant, more environmentally friendly than many building materials, and structurally sound. (Yee, 2010). Though this bio-composite has mainly only been tested for structural building parts as opposed to roof tiles, this idea still has the potential to be made into roofing shingles or a stable roofing foundation on which to build.

The addition of the coupling agent MAPP produced a slight increase in the density that could be explained by a higher compatibility among the filler and the polymer matrix thus diminishing the presence of voids in the material.

tile (tavela) sound, light, heat and ventilation [24]. Every element in nature has acoustic properties and the absorption capacity depends on the type of material this element was made of. When choosing the materials for the acoustic, it is also important As a rice husk based product, it has also been used, together with clay, when manufacturing bricks and roof tiles that have a good thermal insulation and lightweight concrete [27]. The incremental innovation relates to any improvement.
