Research on the Construction and Maintenance of High-Performance Concrete Under Dry-Hot Plateau Conditions
In plateau areas,it is extremely difficult to ensure the construction quality of cement projects due to dry-hot weather,low air humidity,strong ultraviolet radiation and high water evaporation.For this reason,this study aims to explore the formulation of new C30 and C60 cement and the effect of the water-binder ratio and mainte-nance requirements on the hardness of cement during construction,with a view to solving above problems.Results show that under the same ratio condition,the strength of cement with dry-hot curing for 28 days is 43%～80%higher than that in the standard curing environment.Therefore,in order to further improve the quality of concrete,it is recommended to adopt the curing methods of covering water storage devices,filling water regularly and mois-turizing strictly,increase the design hardness of cement and reduce the water-binder ratio accordingly.
