摘要
再生混凝土是当前国际上研究的热点之一,再生混凝土能否用于结构承重。主要是看其强度能否满足要求,而配合比是决定其强度的一个重要因素,水灰比又是配合比中的一个关键参数,再生混凝土单位体积用水量怎样取值就成为一个重要的研究课题。对混合粗骨料十天然砂这一组合进行了试验研究,提出了额外增加用水量的计算公式。从理论上较详细地讨论了其他情况下再生混凝土单位体积用水量的计算,可供再生混凝土配合比设计作参考。
Recyeled concrete research is currently one of the hot spots at home and broad. Whether recycled concrete can be used in construction or not depends on its strength. Mixture ratio is an important factor deciding strength, which is supported by a crucial parameter ; water-cement ratio. So the calculation of water usage per unit volume of recycled concrete becomes an important research topic, The authors have already researched the form of mixed coarse aggregate by adding natural sand for experiment, and the calculating formula for the increased water usage has been put forward, but that in the case of other aggregate combination forms is not discussed, The calculation of water usage per unit volume under other conditions is also discussed in detail, and this will be used as a reference for the desiging of recycled concrete mixture ratio.
