施工工艺对再生碎砖混凝土性能影响的研究
发布时间：2018-07-23 08:43
【摘要】：通过对3种不同施工工艺的再生碎砖混凝土进行力学以及和易性试验研究,结果表明:采用附加水法配制的再生碎砖混凝土随着附加水的减少,其抗压强度提高,但降到粗骨料吸水70%时,其抗压强度提高不明显,而和易性则是按粗骨料的吸水率为80%~90%时表现较好;使用浸泡预湿法和洒水预湿法的再生碎砖混凝土均有较高的抗压强度及较好的和易性。
[Abstract]:The mechanical and easyness tests of recycled broken brick concrete with three different construction techniques are carried out. The results show that the compressive strength of recycled broken brick concrete prepared by additional water method increases with the decrease of additional water. However, when the coarse aggregate absorbs water, the compressive strength of the coarse aggregate does not increase obviously, but the easiness is that when the water absorption rate of coarse aggregate is 80 ~ 90, the compressive strength of the coarse aggregate is better than that of the coarse aggregate. The recycled brick concrete with soaking prewet method and sprinkling prewetting method has higher compressive strength and better ease.
