Investigation of the compressive strength of concrete mixtures prepared using fly ash

Fly ash can turn into a valuable and useful product when used correctly and used as a component material of concrete. Fly ash provides significant benefits to concrete when used in concrete structures due to its pozzolanic properties. The aim of this study is to examine the effect of the chemical composition of fly ash on the compressive strength of concrete. The results obtained from the compressive strength tests of 12 concrete samples using partial cement replacement with fly ash are given. These models were compared with a reference model consisting of 6 samples of pure concrete to estimate the compressive strength of concrete as a function of the apparent composition of fly ash. In this study, concrete samples were created using the same proportions of cement, sand and water. Concrete samples containing fly ash were created by adding 10% and 20% fly ash to 1m3 of concrete at different rates. Curing processes were applied for 3, 7 days and 28 days for the concrete sample without fly ash and concrete samples containing fly ash. According to the test results, the compressive strength of the concrete samples increased with the increase in the amount of fly ash.
