Effect of polyethylene glycol concentrations on compressive strength of concrete
Abstract
This research examined the compressive strength of polyethylene glycol (PEG) modified concrete using polyethylene glycol (PEG) concentrations of 2.5, 5, 7.5 and 10 percent strength. The compressive strength of the controlled concrete is 320 ksc according to the standards of the Department of Highways. This study tested the compressive strength of concrete modified with polyethylene glycol at 7 and 28 days curing. The collapse values when PEG were applied yielded the collapse values of 3, 3, 5.5, 6 and 12 cm, and the concentrations were 0, 2.5, 5, 7.5 and 10%, respectively, and the concrete weight unit at 28 days and the concentration. The values of 0, 2.5, 5, 7.5 and 10% of PEG material were 2446, 2448, 2363, 2405 and 2328 kg/m3, respectively. Concrete at 7 days of age and concentrations were 0, 2.5, 5, 7.5 and 10. % of PEG material were 304, 254, 227, 211, 180 ksc, respectively, and concrete at 28 days was 432, 321, 292, 212 and 196 ksc, respectively.
