Pavement concrete and preparation method thereof
The invention provides pavement concrete as well as a preparation method and application thereof, and belongs to the field of comprehensive recycling of waste aerated concrete. As waste aerated concrete recycled fine aggregate is loose and porous and has very strong water absorption, pre-wetted fine aggregate in a saturated surface dry state is obtained by pre-wetting in advance, it can be ensured that the slump is within a reasonable range, and the result shows that the pre-wetted waste aerated concrete particles have an internal curing effect under the condition that other factors are not changed, on the basis of ensuring the construction performance of the pavement concrete, the mechanical property, wear resistance and the like of the pavement concrete meet related requirements, and compared with the performance of a control group (pavement concrete not replaced by waste aerated concrete), the performance of the pavement concrete is not greatly reduced, and engineering practice can be guided.
本发明提供了一种路面混凝土及其制备方法和应用，属于废弃加气混凝土的综合再生利用领域。由于废弃加气混凝土再生细集料疏松多孔，具有很强的吸水性，因此提前预湿得到饱和面干状态的预湿细集料，保证塌落度在合理的范围之内，结果表明，在其他因素均不改变的情况下，预湿后的废弃加气混凝土颗粒由于具有内养护作用，在保证路面混凝土施工性能的基础上，路面混凝土的力学性能、耐磨性能等均满足相关要求，且与对照组(未使用废弃加气混凝土替代的路面混凝土)相比不会出现大幅下降，有利于指导工程实践。
