Abstract:There are very much difference between temperature and humidity of the Qire Hataer hydropowerstation diversion tunnel in different hole,which has different degrees of influence on the performanceof the sprayed concrete.Through the simulation test method,this paper simulated field indifferent temperature and humidity environment,the blocks were maintained and tested,and analysisof the influence of temperature and humidity on concrete block was analyzed from the microscopic aspectby using the methods of casting concrete and jet concrete experiment.Finally,it is concludedthat the environment of high temperature curing can improve the early strength of concrete of testblock,but also can promote the hydration reaction inside the concrete.
