摘要：
This study aimed to reduce radon exhalation from coal fly ash-containing concrete bricks (CFA-containing concrete brick). A measurement device for determining the radon exhalation rate was designed and optimized. The device can control the temperature and humidity of the environment during the CFA-containing concrete bricks are measured. Two types of CFA-containing concrete bricks were designed in this study, and their radon exhalation rates were evaluated. (1) Sodium silicate (SS) and polyvinyl alcohol (PVA) were used as additives to fabricate CFA-containing concrete bricks to evaluate the ra...
