Engineering Properties of Permeable Polymer Concrete with Blast Furnace Slag and Fly Ash

This study is performed to evaluate the engineering properties of permeable polymer concrete with blast furnace slag and fly ash. The following conclusions are drawn; 1. The highest strength is achieved by 50% filled blast furnace slag powder and fly ash permeable polymer concrete, it is increased 36% by compressive strength, 119% by tensile strength and 217% by bending strength than that of the normal cement concrete, respectively. 2. The ultrasonic pulse velocity is in the range of 2,022 ∼ 2,139m/s. The highest pulse velocity is showed by 50% filled blast furnace slag powder and fly ash permeable polymer concrete. 3. The water permeability is in the range of 4.612∼5.913$\ell$/$\textrm{cm}^2$/h, and it is largely dependent upon the mix design.
