Abstract

------28/04/2564------(OCR) Concrete bricks from recycled glass and their manufacturing process. This invention describes a concrete brick made from recycled glass, partially replacing fine aggregate (coarse sand), combined with Portland cement as a binder, coarse sand, and water. The mixing ratio for producing the concrete bricks is Portland cement : coarse sand : water = 1:3:0.5 by weight. 20% by weight of the coarse sand is replaced with recycled glass. The mixture is then poured into molds, left for 24 hours, and then removed from the molds. The bricks are cured in water at normal temperature for 28 days, and then sun-dried for 5-7 days to obtain usable concrete bricks. ------------ Page 1 of 1. Summary of the Invention: Concrete bricks from recycled glass and their manufacturing process. This invention describes a concrete brick made from recycled glass, partially replacing fine aggregate (coarse sand), combined with Portland cement. Acting as a binder, coarse sand and water are used in the mixing ratio for producing concrete bricks. The ratio is Portland cement : coarse sand : water in a ratio of 1:3:0.5 by weight. 20% by weight of the coarse sand is replaced with crushed sand. The mixture is then poured into molds and left for 24 hours. After removal, the bricks are cured in water at room temperature for 28 days. Finally, the concrete bricks are sun-dried for 5-7 days to obtain usable concrete bricks.

Claims (2)

------28/04/2564------(OCR) 1. Concrete bricks made from recycled glass, composed of a concrete brick mix ratio of Portland cement : coarse sand : water equal to 1:3:0.5 by weight, with 20% by weight of coarse sand replaced by recycled glass. 2. The manufacturing process of concrete bricks from recycled glass, as per claim 1, consists of the following steps: a. Washing and cleaning the recycled glass, then drying it. b. Grinding the recycled glass from step a to reduce its size to no more than 4.75 mm, then sieving it through a No. 4 sieve and retaining it on a No. 100 sieve. c. Using the recycled glass from step b to replace some of the coarse river sand, mix it with Portland cement and water, with the concrete brick mix ratio being Portland cement : coarse sand : water equal to 1:3:0.5 by weight, with 20% by weight of coarse sand replaced by recycled glass. d. Mixing the dry materials from step c, namely recycled glass, coarse sand, and Portland cement, until homogeneous, then adding water. Next, mix for another 1-2 minutes, then pour the mixture into the mold. Leave it for 24 hours, then remove the sample from the mold. Next, remove the concrete bricks obtained from step d from the mold and cure them by soaking them in water at room temperature for 28 days. Finally, dry the concrete bricks obtained from step e in the sun for 5-7 days. This will yield ready-to-use concrete bricks made from recycled glass. ------------ Page 1 of 1 Claims 1. Concrete bricks made from recycled glass are constructed using a concrete mix ratio of Portland cement : coarse sand : water in a ratio of 1:3:0.5 by weight, with 20% by weight of coarse sand replaced by recycled glass. 2. The process for producing concrete bricks from recycled glass, as per claim 1, consists of the following steps: a. Washing and cleaning the recycled glass, then drying it. b. The recycled glass from step a is then fed into a fine grinder to reduce its size to no more than 4.75 millimeters, sieving it through a No. 4 sieve and retaining it on a No. 100 sieve. c. The recycled glass from step b, to partially replace coarse river sand, is mixed with Portland cement and water. The mixing ratio for the concrete bricks is Portland cement:coarse sand:water = 1:3:0.5 by weight, replacing 20% by weight of coarse sand with recycled glass. d. The dry materials from step c—recycled glass, coarse sand, and Portland cement—are mixed until homogeneous, then water is added. The mixture is then mixed for another 1-2 minutes, after which the mixture is poured into molds and left for 24 hours. Samples are then removed from the molds. e. The concrete bricks obtained from step d are removed from the molds. Then, cure them by soaking them in water at room temperature for 28 days. Next, take the concrete bricks obtained in step E and dry them in the sun for 5-7 days. This will result in ready-to-use concrete bricks made from recycled glass.
