附着砂浆含量对再生混凝土抗压强度的影响

Attached Mortar Content on the Compressive Strength of Recycled Concrete

试验目的是研究再生混凝土骨料附着砂浆含量对再生混凝土抗压强度的影响;采用微波循环加热次数控制再生骨料附着砂浆含量,附着砂浆使再生混凝土的抗压强度低于天然混凝土,并随砂浆含量减少,再生混凝土强度增加。

The experiment aims to study the influence of re- cycled concrete aggregate adhered mortar content on the Com- pressive strength of recycled aggregate concrete; The experiment adopts microwave heating to control the content of recycled aggre- gate, The recycled aggregate adhered mortar make recycled con- crete compressive strength of concrete is lower than natural con- crete, and with mortar content decreased, increasing the strength of recycled concrete.
