Abstract

Air inside buildings can be more polluted than outdoor because there are various sources of pollution in some big cities. This paper presents the results of a study on the efficiency of contributing air cleaning agents such as Titanium dioxide (TiO2) into the technique of producing concrete composite panels, using local waste materials for solving the problem of carbon dioxide (CO2) in indoor air buildings. Factors which would have an effect on the performance of the panel were studied, including the porosity of panel, different types of waste materials and types percentage of TiO2 used within the mix design. The degradation process under laboratory conditions was studied using chemiluminescence analysis method for measuring the performance of photocatalytic active concrete products. The results show that the photo degradation of CO2 is related to the porosity of the sample; when the porosity of sample was increased, the CO2 had removal ability.
