Abstract
In this report the theoretical and experimental study on Air Permeable Concrete has been performed. The research focused on establishing the mix designs for APC in order to obtain desired properties, such as high poro- sity and permeability and satisfactory compressive strength. The addition of Phase Change Materials was considered and their influence on the rheo- logy of cement paste and on the compressive strength of APC was evaluated. The establishment of the mix designs was based on the tests of the rheo- logy of cement paste and the workability of concrete. The concrete with water/cement ratios of 0.30 and 0.35 together with three different degrees of filling (0.4, 0.5, 0.6) for each water/cement ratio has been tested. The experimental study focused on developing the methods of mixing, casting and curing which enable obtaining the desired properties of APC. The methods of measurements of the parameters have been determined and the tests of porosity, permeability and compressive strength have been per- formed. The calculation of theoretical values of porosity has been done and compared with laboratory results. The comparison of obtained results with results from other studies on APC has been performed.
