| Abstract: | The solar radiation absorption coefficient of concrete surface is one of the important parameters in the analysis of thermal problems in concrete structures. Based on basic formulation for thermal balance, an experimental method to measure the solar radiation absorption coefficient of concrete surface is suggested. After testing on concrete elements with different surface characteristics, the influence of the roughness and the color difference of concrete surface on the solar radiation absorption coefficient is analyzed. Ben, the suggested value of the solar radiation absorption coefficient of concrete surface is presented. The methods that could be used to reduce the thermal affection on structures are discussed. |
| Keywords: | concrete absorption coefficient of surface solar radiation |
