Abstract

DC60 (February 9, 2015) A sheet material containing rice husk ash powder and a manufacturing process. The mixture consists of rice husk ash powder mixed with Portland cement, fine sand, and water. This mixture is then molded into the desired shape using a mold and cured for a specified period. The resulting product has a naturally dark color without the need for added or coated synthetic dyes. It can be used in products requiring high strength, such as roof tiles, floor tiles, or wall bricks.

Claims (2)

Revised 16/02/58 (9/02/2015) 1. The rice husk ash composite material sheet has the following components: a. Fine sand, 80 percent by weight of the dry mixture. b. Portland cement, 14-19 percent by weight of the dry mixture. c. Finely ground rice husk ash powder, 1-6 percent by weight of the dry mixture. d. Water, 16-25 percent by weight of the total dry mixture. 2. The manufacturing process of the rice husk ash composite material sheet, as per claim 1, involves the following steps: a. Sift the rice husk ash using a No. 35 sieve to remove impurities. Then, dry grind it for 1.5-3 hours. The resulting rice husk ash powder should pass through a standard No. 325 sieve. b. Sift the sand through a standard No. 35 sieve. c. Mix the fine sand and Portland cement. 1. Mix the finely ground rice husk ash powder thoroughly for 10-30 minutes. 2. Add water to the mixture and mix well for 1-5 minutes. 3. Mold the mixture using a mold. 4. Allow the mixture to harden for 12-24 hours at room temperature. 5. Cure under 90-100% relative humidity for 7-14 days. ---------------------------------------------------------- 1. A sheet of material containing rice husk ash has the following components: a.
