本文应用表观密度较低的陶砂粒度及粒径较小的济宁陶粒,辅以黄原胶和引气剂来提升混凝土的抗离析性能。通过相关技术参数的调整,可配制出坍落度为210mm、28d抗压强度为13.9MPa、表观密度为1150kg/m3、施工性能良好的LC10轻骨料混凝土。
In this paper, the lower the apparent density of ceramic sand and particle size smaller Jining ceramsite, with xanthan gum and air-entraining agent to enhance the anti-segregation performance of concrete. Through the adjustment of relevant technical parameters, LC10 lightweight aggregate concrete with slump of 210mm, 28d compressive strength of 13.9MPa and apparent density of 1150kg / m3 can be prepared.
