部分建筑材料氡析出率测试分析

Measurement of Radon Exhalation Rate from some Construction Materials

混凝土空心砌块、加气混凝土等新型建筑材料是目前房屋建筑通用的墙体建筑材料。本文通过实验测量了混凝土空心砌块、水泥砂浆、加气混凝土等建筑材料在相同的环境条件下氡析出的规律,测试了水泥砂浆覆面对建筑材料氡析出的影响,比较了部分建筑材料氡析出率的不同,为民用建筑防氡降氡设计和建筑材料的选用提供数据资料。

Newly emerging building materials,such as concrete hollow block and aerated concrete,is currently general wall construction materials.Radon exhalation from concrete hollow block,cement mortar and aerated concrete was measured through experiment under the same environmental conditions.The impacts of cement mortar overburden on radon exhalation rate from construction materials were evaluated and comparison of radon exhalation rates from different materials was made.This can provide data for the choice of construction materials in aspects of prevention and reduction of radon.
