Özet:
Pervious concrete is a type of special concrete that is formed with interconnected pores. It is able to pass the stormwater through its pores in order to control surface runoff and groundwater effectively. Due to the environmental benefits of pervious concrete, the usage of it has been increased day by day. In this thesis, the properties of pervious concrete by using excess paste theory and image analysis method were investigated. Concrete mixtures were prepared with four different aggregate gradations by combining three aggregate sizes (4-8 mm, 8-12.5mm and 12.5-16 mm), three different volume of paste to the volume of aggregate ratios (0.39, 0.42, and 0.45) and superplasticizer in three different ratios (0.5%, 0.7%, and 0.9%). For the determination of paste thickness in pervious concrete, excess paste theory and image analysis were used. For the determination of surface area of aggregate AutoCAD ReCap and some models were used. For the determination of fresh properties of pervious concrete, slump test, the density test of fresh pervious concrete and rheological measurements of cement paste were done. Permeability, compressive and flexural strength, abrasion resistance, density test, and void content tests were performed on hardened pervious concrete. To sum up, just as paste thickness results, the ratio volume of paste to the volume of aggregate, aggregate gradations, and the usage ratios of superplasticizer affected the performance of concrete. Results showed that increasing paste to aggregate ratio and superplasticizer dosage caused more workable concrete, more paste thickness, less permeability, less void, and more compressive strength.
