砖含量对再生混凝土抗压强度影响的试验研究

On test of influence of brick contents on compressive strength of recycled concrete

通过试验,研究了砖含量对再生混凝土抗压强度的影响,试验结果表明:当水胶比较大时,随着再生粗骨料中砖含量的增加,混凝土的抗压强度有所降低;当水胶比较小时,随着砖含量的增加,混凝土的抗压强度反而有所提高。

According to some tests, the paper researches the influence of the brick content on the compressive strength of the recycled concrete, proves by the test results that the concrete compressive strength is lowered by adding the brick content of the recycled course aggregate when the water-binder ratio is bigger, the compressive strength is improved with added brick contents when the water-binder ratio is small.
