摘要
文中针对某项目混凝土表面出现大面积点状爆裂现象,通过现场取样对病害部位混凝土进行强度体积稳定性和X射线荧光成分分析(XRF))等项目检测和分析,结果表明,病害部位存在游离氧化钙(f-CaO)的潜在危害,而f-CaO较大可能是不合格钢渣所致。
A large area of concrete surface point like cracking occurred in a certain project's concrete structure.Through on-site sampling,strength volume stability and X-ray fluorescence composition analysis(XRF)tests were conducted on the affected concrete.The results showed that there is a potential danger of free calcium oxide in the affected area,and the large amount of free calcium oxide may be caused by the use of unqualified stel slag in the concrete.
