Impact strength of meta kaolin and fly ash concrete
MetadataShow full item record
This research to study the possibility of material pozzolan as binder by replacment cement by fly ash (FA) and meta kaolin (MK), some for testing compressive strength, flexural strength and impact strength of concrete vary the ratio of water to binder (w / b) of 0.40 and 0.45 and the amount of fly ash to replace cement, some 15 %, 30 % MK and 35% for 10%, 15% and 20% by weight of cement. The sample consisted of a cylinder diameter of 10 x 20 cm beam sizes 10 x 10 x 40 cm and 4 x 4 x 16 cm from the test results showed that the concrete samples at 28 days and w/ b of 0.40 to greater than 0.45 all mixed. the compressive strength by replacing cement with FA increase up to 30 % compression of 382 ksc higher than the 20 percent replace by MK were equal to 354 ksc and 32.48 ksc compared to replace cement with FA, 15 % is equal to 31 ksc, 30% were equal to 30 ksc and 45% were equal to 23.85 ksc, while the MK was replaced by 10% were equal to 40.10 ksc higher than to 15%, and 20% respectively. The control sample was replaced with MK by 10% is equal to 111 joules maximum replaced by fly ash more than 30% were equal to 110 joules and MK were 15%, fly ash, 15 and 45 percent respectively.
