TH17295C3 - Artificial gypsum concrete brick with oil palm tree remains And manufacturing processes - Google Patents

Abstract

1 page of 1 page Summary of the invention The invention involved concrete bricks from artificial gypsum combined with oil palm remains, composed of Portland cement and artificial gypsum. acts as a coordinator fine aggregate, coarse aggregate, and palm oil and water palm remains, where the weight ratio between Portland cement and artificial gypsum per fine aggregate The ratio of oil palm coarse crude aggregate to water was 1-2: 2-4: 4-8: 0.5-1, where the weight ratio between portland cement to artificial gypsum was 94.5 to 5.5 and the weight ratio between coarse aggregates per palm oil palm husk was 99.5:0.5. The production process was done by mixing Portland cement. fine aggregates, coarse aggregates, water, gypsum, artificial and oil palm remains. stir until homogeneous Then pour the mixed material into the print. After that take the brick out of print and incubated for a specified period of time then take it to the sun will get concrete bricks from Artificial gypsum, concrete bricks from artificial gypsum combined with oil palm remains.

Disclaimer (all) which will not appear on the advertisement page: page 1 of the number 1 disclaimer 1. Concrete bricks made from artificial gypsum with oil palm residue consisted of portland cement and artificial gypsum. Acts as a binder Fine aggregates Coarse aggregates and The remains of palm trees, oil and water, with the weight ratio between Portland cement and artificial gypsum to fine aggregates. Per coarse aggregate, oil palm remains per water is 1-2 per 2-4 per 4-8 per 0.5-1. 2.Concrete bricks from artificial gypsum According to claim 1, where the ratio by weight between Portland cement The artificial gypsum is 94.5 to 5.5. 3.Concrete bricks from artificial gypsum According to claim 1, where the weight ratio between the coarse aggregate to the carcass of oil palm is 99.5 to 0.5. 4.Concrete bricks from artificial gypsum According to claim 1, where fine aggregates can be chosen from round or square materials. Not flattened Rough surface and hard grains, clean, durable, including sand, stone particles, river sand, land sand, mine sand, calcined clay of any type or a mixture From two kinds 5.Concrete bricks from artificial gypsum. According to claim 1 or 4, where the fine aggregates are between 4.75 - 80 mm. 6. Concrete bricks made from artificial gypsum. According to claim 1, where coarse aggregates can be selected from hard, durable, non-decaying, flat or excessively long, clean grains, namely gravel, gravel, gravel, gravel, one type of river gravel or a mixture of two types.7. Concrete bricks from artificial gypsum According to claim 1 or 6, where the coarse aggregates are between 75 microns - 4.75 mm. 6. Process for producing concrete bricks from artificial gypsum with oil palm tree remains According to any 1 to 7 claim The steps are as follows: a) The artificial gypsum by applying to the sun to dry. And the oil palm trunks were dried in the sun for 14-16 days and then reduced in size with a grinder. Then mixed with portland cement The fine aggregates, coarse aggregates and the water are stirred to homogeneous. Then left for 24-48 hours to become concrete bricks. C) Remove the concrete bricks obtained in step b) from the mold and curing by soaking in water at 20-25 ° C for 14-28 days after. They were exposed to the sun for a period of 5-7 days. Concrete bricks were obtained from artificial gypsum with the remains of oil palm trees.
