微波养护对水泥砂浆性能与微观结构的影响
Effect of Microwave Curing on Properties and Microstructure of Cement Mortar
摘要
Abstract
Microwave curing technology of concrete can significantly improve the early strength of concrete,but there is no uniform design standard for microwave curing method,resulting in great differences in material properties after cur-ing.To explore the influence of microwave curing methods,this study employed the response surface methodology to sys-tematically analyze the influence of microwave curing method on the compressive strength of cement mortar.The relation-ship model between key microwave curing parameters and material properties was established,and the optimal micro-wave curing method was determined when the heating temperature was under 40℃and the heating power was 1 000 W for 30 min.Chemical components and microstructure impacts were studied using X-ray diffraction(XRD),mercury intru-sion porosimetry(MIP),and scanning electron microscope(SEM),and it was revealed that a reasonable microwave cur-ing method can promote the hydration degree of mortar and form a denser structure.The temperature variation in micro-wave curing process was analyzed by combining experimental data and computer simulation,and it was found that micro-wave curing temperature had hot spot effect.It is concluded that microwave curing temperature is the most important fac-tor affecting the strength of mortar.关键词
