再生混凝土多孔砖耐水性试验研究

Experimental study on the water resistance of the recycled concrete porous brick

通过对5组不同配合比的再生混凝土多孔砖进行耐水性试验,研究了砖的抗压强度及抗折强度软化系数与配合比、吸水率的关系,并对蒸压粉煤灰多孔砖、蒸压灰砂砖、烧结页岩砖进行了对比试验,比较分析了再生混凝土多孔砖的耐水性。结果表明,再生混凝土多孔砖的耐水性整体上较好,满足耐水性材料的要求。

Through water resistance test on the five groups of recycled concrete porous bricks with different mix proportions, the relationship between compressive strength,tensile strength,softening coefficient and mix proportion,water absorption were studied. Meanwhile,by contrasting test of the autoclaved fly ash porous brick, autoclaved suggested brick and sintering confined shale brick,water resistance of the recycled concrete porous brick was analyzed. Comparative analysis result showed that water resistance of the recycled concrete porous brick is overall good, meeting the requirements of the material.
