Abstract

Investigation to improve the performance of the pervious concrete is required through possible modifications in its properties, as it is utilized in different applications through civil engineering projects, especially in pavements. To save time and costs, such pavements should serve and explore to the traffic and the users as soon as possible. Concretes should be cured for at least 28 days to gain sufficient strength to withstand applied loads. To shorten this period, studying the properties of plain pervious concrete in terms of the mechanical properties and the permeability was undertaken. Single sized natural coarse aggregate conducted at constant water-to-cement ratio of 0.27 with cement content of 450 kg/m3, four curing period and two curing system (moist and steam) as experimental parameters were followed in this study. The results compared the two systems of curing for plain pervious concrete samples to show the effects of high temperature regime on the mechanical and permeability properties. The elevated temperature improved the mechanical properties in earlier ages but has no effect on the permeability while the steam curing resulted in an increase in modules of elasticity
