污水环境中清水混凝土保护剂对混凝土抗压强度的影响

Effect of Clearwater Concrete Protectants on Compressive Strength of Concrete in Wastewater Environment

为探究清水混凝土保护剂对污水环境中混凝土的抗压强度的影响,将分别涂刷了氟碳类、有机硅类、丙烯酸类清水混凝土保护剂的3组混凝土试块和1组标准试块在人工强化污水中进行腐蚀试验,对经过90 d人工强化污水腐蚀后的混凝土试块进行抗压强度试验。试验结果显示,与标准试件相比,经过3种清水混凝土保护剂涂刷后的试块的抗压强度均相对较高。3种清水混凝土保护剂对污水中的混凝土的强度降低均有明显的延缓作用。

In order to investigate the effect of cleanwater concrete protectants on the compressive strength of concrete in wastewater environment,three groups of concrete specimens coated respectively with fluorocarbon protectant,silicone protectant and acrylic concrete protectant and one group of standard specimens were corroded in artificially reinforced wastewater for 90 days,and then compressive strength of the concrete specimens were tested. The test results showed that the concrete specimens coated respectively with the three types of clearwater concrete protectants had higher compressive strength than that of standard specimens,three concrete protectants had a significant retarding effect on the strength reduction of concrete in the wastewater.
