Using method of foaming self-breaking concrete based on microwave excitation

A using method of foaming self-breaking concrete based on microwave excitation is characterized in that self-breaking concrete containing a vulcanizing agent, a foaming agent, rubber powder, a microwave absorbent and perlite or vermiculite is poured to form a temporary support structure, a microwave field is applied to a pouring area when the temporary structure is dismounted or destroyed, the mutual cooperation of all above components realizes the rapid rising of the temperature in the concrete, the foaming agent foams and vents gas at a high temperature, and coarse and fine aggregates expandat a high temperature, so the concrete rapidly cracks, and is self-broken. The strength of the concrete after breaking is greatly reduced, so the temporary support structure poured by using the concrete is easy to dismount, the time is saved, and the construction difficulty is reduced. 本发明的种基于微波激发的发泡自碎型混凝土的使用方法，通过采用添加有硫化剂、发泡剂、橡胶粉、微波吸收剂及珍珠岩或蛭石的自碎型混凝土浇筑临时支护结构，在拆除或破坏临时结构时，向浇筑区域内施加微波场，通过各组份间的相互配合，可实现混凝土内部的温度的迅速升高，发泡剂在高温下进行发泡
