早期混凝土由于水化反应都会产生体积变化.如果体积变形受到约束就会产生应力,一旦超过混凝土的抗拉强度就会产生裂缝.由于早期混凝土的力学性能是随时间变化的,特别是徐变,它不仅与加载时间有关而且同时随龄期而变化,因此计算早期混凝土结构应力是较为复杂的问题.有限单元法不仅可以考虑混凝土刚度的变化,而且可以考虑温度、徐变、收缩等因素.本文利用初应力法对通用有限元软件ansys进行了二次开发,通过工程实例计算了高层建筑地下室侧墙早期混凝土应力的变化过程,并提出了相应的抗裂措施 | | 7. | It is indicated that the hydration process of cement - based materials with slag , fly ash and silica fume is different in some degree from that of neat cement because of the difference in mineral structure and hydration mechanism . the periods of accelerating , decelerating and terminating are prolonged and hydration reaction decelerates . the second peak of rate curve of the heat evolution could be divided into two small peaks , which are contributed to the hydration of clinkers and mineral mixtures at the temperature of 30 but when temperature comes to 50 , the two small peaks combine into one and the reaction accelerates
