Experimental Study on RCC Character of Additive MgO and Simulation of Crack Prevention in High Temperature Construction
Characteristics of RCC concrete with greater proportion of magnesium oxide style in domestic are few mentioned, urgently awaits to further study. Through the test of additive magnesium oxide roller compacted concrete's characteristics, to determine the appropriate magnesium oxide style admixture of roller compacted concrete; Accurately calculation the temperature field and stress field of the simulation, the results show the mixed magnesium oxide technology and bury HDPE cooling water pipes measures combining to RCC construction of high-temperature cracking is an effective method of temperature control and crack prevention. It is for the high-temperature environment of RCC dam construction scheme has provided important scientific basis.
