Abstract
The purpose of this project is to study the use of crumbs of prestressed concrete pile to mix into coarse aggregates in the production of porous concrete to compare various properties by modifying the volume of cement paste that was binding materials in the ratio of 40, 42, 44, 46 and 48 percent of the prestressed pile weight to know the suitable ratio for use. The result of the properties of porous concrete mixed with crumbs of prestressed pile is a coarse aggregate material was found that when the volume of cement paste was increased get porous concrete mixed with crumbs of prestressed pile has compression was increased but the attrition of concrete and water flow was decreased which found that CB-44, which is the ratio of cement paste 44 percent of the weight of prestressed concrete pile and able to handle a maximum compressive strength of 138.47 kilograms per square centimeter. The water flow test is 1.03 centimeters per second and the resulting test of attrition of concrete was 5.00 grams. Suitable for use in perforated concrete projects that are private car parks.
