Basics Properties of Cannabis Concrete from Cannabis Shiv Containing Fly Ash

Abstract

This research presents the use of crushed dried cannabis shiv as coarse aggregate in concrete mixes. Dried cannabis shiv is crushed to a small size, using standard sieve No. 4# and No. 8# is 35 and 65 percent. Use the ratio (CS/C) = 0.16, use fly ash instead of hydraulic cement at the ratio of 0, 10, 20, 30, 40, 50 and 90 by weight. The ratio of hydraulic cement to fine aggregate (C:S) was 1:2. The ratio of water to hydraulic cement (W/C) was 0.48. The superplasticizer was used at 1% by weight of hydraulic cement. Using the ratio of 〖" Al" 〗_"2" "(" 〖"SO" 〗_"4" ")" : Ca〖"(OH" 〗_"2" ")" was 1: 2 for use as an alkaline solution, and the volume of the solution was used to improve the quality of the cannabis shiv at 54 % by weight of the cannabis core Before being used as a coarse aggregate. The compressive strength, unit weight, water absorption and volumetric dry shrinkage of cannabis concrete were tested. Compared with the control normal concrete set at 7, 14, 28 and 56 days of age. The results showed that at the age of 28 and 56 days compressive strength is in the range of 90.59 to 155.44 kg/sq.cm. unit weight 1,373 to 1,781 kg/cu.m. water absorption 9.23 to 25.13 percent and dry shrinkage 0.89 to 1.75 percent. From the test results, it was also found that The use of fly ash in place of increased amounts of cement significantly contributed to the development of increased and decreased strength of cannabis concrete. The optimal ratio for use that meets the criteria for the ACI213R-87 recommendation is the CSCF20 ratio.
