Physical treatment method of cement mortar/concrete mixture
The invention provides a physical treatment method of a cement mortar/concrete mixture, which comprises the following steps: carrying out physical ultrasonic treatment on the cement mortar/concrete mixture at the ultrasonic vibration frequency of 15KHz-50KHz, the ultrasonic vibration treatment time of t and the ultrasonic treatment time point of T; wherein the cement mortar/concrete mixture contains an additive, and the additive is used for improving the flowing property of the mixed slurry or prolonging the setting time. The physical treatment can be carried out immediately after the concrete is just mixed, can also be carried out at a certain time point from mixing to pouring, can also be carried out in the pouring process, and can also be carried out from pouring to condensation of the concrete; the method can also be carried out for multiple times at different time points. The ultrasonic treatment can weaken the inhibition effect of the admixture on cement hydration, promote the setting and hardening of cement mortar or a concrete mixture, improve the early strength development of the cement mortar or the concrete mixture, shorten the form stripping time of the precast concrete component and save energy.
本申请提供了一种水泥砂浆/混凝土拌合物的物理处理方法，包括：对水泥砂浆/混凝土拌合物进行物理超声处理，超声振动频率为15KHz～50KHz，超声振动处理时间为t，超声处理的时间点为T；其中，水泥砂浆/混凝土拌合物中含有外加剂，外加剂用于提高拌合浆料的流动性能或延长凝结时间。这种物理处理可以在混凝土刚刚拌合完成后立即进行，也可以在拌合后到浇筑前的某一时间点进行，也可以在浇筑过程中进行，也可以在混凝土完成浇筑后到凝结前进行；也可在上述不同时间点多次进行。超声处理能够减弱外加剂对水泥水化的抑制作用，促进水泥砂浆或混凝土拌合物的凝结硬化，提高水泥砂浆或混凝土拌合物早期强度发展，缩短混凝土预制构件的拆模时间，节约能源。
