Application

Rice Husk Ash Applications

RHA can be used in a variety of industries with the highest applications in the steel plants and in special blends of cement and concrete admixtures.

Following are some of the applications of the rice husk ash;12

With an extraordinary for binding property of carbonized rice husk ash is a unique, therefore the suitable industries which will use it, are steel and cement industries.

• Rice Husk Ash powder for steel production and foundry
• Rice Husk Ash (RHA) has been widely used as an insulation powder in steel casting tundish. Its effect on the reoxidation of molten steel in turdish. 
• The insulation helps to maintain the correct temperature of the metal
• Steelmaking
• Silica fume
• Thermal Insulation
• Tundish covering powder
• Casting Refractory

To recycle the refractories that need to be disposed by various industries into value added raw materials that can be re-used by refractory manufacturers. RHA is an excellent insulator , by RHA property is thermal insulation by preventing a rapid cooling of the steel uniformly at high melting point that could produce of high quality steel with continuous casting, moreover the zero carbon rice husk ash is a conventional raw material or as a binder, so with these point the zero carbon rice husk ash mainly use in steel and cement industries.

Rice husk ash is CO₂- neutral raw material. During its combustion, only the same ampunt of CO₂ is released.

Application :

• Steel Industry (Casting tundish, Casting ladle, ingot casting) as heat insulation covering compound

Cement & Concrete Industry

A mixture of rice husk ash or fly ash and alkaline solution as a material with binding property, i.e. similar to Portland cement,which it can be use as a substitute for bricks, which it’s reducing the cost of producing bricks in the construction materials.

RHA is an excellent material in the production of special cement and concrete mixes, high performance concrete, high strength, low permeability concrete, for use in bridges, marine environments, nuclear power plants, etc. Additional of rice husk ash to concrete lowers the heat of hydration by as much as 30% and prevents the formation of cracks during casting. 

Fiber Cement Industry

In the roof tiles and wood artificial materials.

Manufacturing refractory Bricks

With RHA property is a good thermal insulation and a high melting point, so it has to import rice husk ash brick manufacturing refractory bricksor high heat.

Lightweight construction materials

 RHA properties are an insulation, lightweight, therefore in some developing counties are using Rice Husk Ash for translucent thermal insulation.

Insect Protection

In agricultural, some countries in Asia included Thailand, we use rice husk ash mixed with seeds for prevent agricultural produce from pests.

Silicon Chips in Semiconductor devices manufacture

Wafers, which it used in this manufacturer must use pure silicon in the production.

 Fertilizer Application

Rice husk ash or black rice husk, it is rice husks or rice husks that have been burned into charcoal. They are lightweight, very porous, water-absorbing, and contain minerals that are beneficial to plants. is 95% silica compound.

Outstanding features

• Rice husk ashes are used for nurseries and nurseries. 
• This allows the roots of plants to spread well. Rice husk ash can be used to grow all kinds of vegetable seeds helps to grow well.
• Use rice husk ash to improve soil physical conditions such as ventilation, water absorption, water holding capacity, making the clay soil not cracked when dry.
• Rice husk ash reduces soil acidity increase soil temperature stimulate the activity of soil microorganisms No pathogens. 

In addition, in mixing rice husk ash into the soil it also helps reduce global warming, because rice husk ash is carbon, they are resistant to microbial degradation and are difficult to lose from the soil therefore it accumulates in the soil. It adds carbon to the soil rather than burning it as carbon dioxide into the atmosphere, one of the causes of global warming.

Rice husk ash is very porous, light weight, has a large surface area. It has moisture absorbing properties and chemicals well.
