为配制高性能绿色混凝土,用不同质量分数的粉煤灰（0%~30%）来替代水泥,并在混凝土中掺入不同质量分数纳米颗粒氧化锌（0%~3%）来提高混凝土的抗压强度、抗拉强度和抗氯离子性能。通过制备30组混凝土试块进行试验,得出：1）在粉煤灰替代率相同的情况下,随着纳米颗粒氧化锌含量的增加,纳米颗粒氧化锌粉煤灰混凝土的抗压强度、抗拉强度和抗氯离子性能均逐渐增加。2）在纳米颗粒氧化锌含量相同的情况下,随着粉煤灰替代率的增加,纳米颗粒氧化锌粉煤灰混凝土的抗压强度和抗拉强度均逐渐下降。但纳米颗粒氧化锌粉煤灰混凝土的抗氯离子性能却逐渐提高。因此,当纳米颗粒氧化锌质量分数为1%时,建议粉煤灰的替代率在10%以下;当纳米颗粒氧化锌质量分数为2%时,建议粉煤灰的替代率在20%以下;而纳米颗粒氧化锌质量分数为3%时,建议粉煤灰的替代率仍在20%以下,因此不建议纳米颗粒氧化锌的掺量超过2%。

：In order to prepare high-performance green concrete,fly ash with different mass fraction （0%~30%） was used to replace cement,and different mass fraction of ZnO nano particles（0%~3%） was added into the concrete to improve the com-pressive strength,tensile strength and chlorine resistance of concrete.Through the preparation of 30 groups of concrete test block test,the results showed that 1）with the increase of ZnO nano particles content,the compressive strength,tensile strength and chlorine resistance of concrete with ZnO nano particles fly ash gradually increased under the same replacement rate of fly ash,2）when the content of nano ZnO was the same,the compressive strength and tensile strength of ZnO nano parti-cles fly ash concrete gradually decreased with the increase of replacement rate of fly ash. However,the chloride resistance of ZnO nano particles fly ash concrete was gradually improved.Therefore,when the content of nano particle ZnO was 1%,the re-placement rate of fly ash was recommended to be below 10%;when the content of nano particle ZnO was 2%,the replacement rate of fly ash was recommended to be less than 20%;when the content of nano particle ZnO was 3%,the replacement rate of fly ash was still below 20%,so it was not recommended that the content of nano particle ZnO exceeded 2%.
