Description

一种超轻保温材料混凝土
技术领域
本发明涉及建筑材料技术领域，主要是混凝土技术领域。
背景技术
当前，世界各国越来越重视建筑节能，建筑节能材料备受市场青睐，尤其是质轻、保温性能好的超轻保温混凝土材料，在建筑领域得到越来越广泛的采用。此外，由于超轻保温材料混凝土的制备不使用燃煤，不产生废水、废气等污染物，以普通水泥为主要材料，填充砂料、石粉、矿渣、粉煤灰等工业废渣，节约能源、保护耕地、可减轻和消除对环境的污染，是绿色环保的新型墙体材料，因而具有十分广阔的应用前景。
现有的超轻保温材料混凝土所使用的保温材料主要为陶粒和如聚苯乙烯泡沫颗粒一类的生活废弃物。陶粒具有轻质、高强、导热系数低、吸水率小等特点，聚苯乙烯泡沫颗粒具有轻质、吸水率小、导热系数低、保温效果好等特点，两者都是保温隔热、防火、防潮、吸音降噪等应用领域的优良材料。但由于现有技术在利用这些材料制作混凝土时，一直没有研究出合理的技术方案，试制的混凝土大都存在强度低或抗渗性差，应用领域窄、泵送困难等问题，严重阻碍了超轻保温材料混凝土在建筑施工中的应用。
发明内容
本发明的目的在于解决现有技术存在的不足，提供一种强度高，抗渗性能好，施工性能好、绿色环保的超轻保温材料混凝土。
本发明的目的是通过如下技术方案实现的。
一种超轻保温材料混凝土，采用以下方法制得：采用5％～20％体积的的生活废弃或工业生产的聚苯乙烯泡沫颗粒、45％～55％体积的陶粒或陶粒与山砂的混合物，6％～14％体积的水泥，8％～18％体积的工业废渣，18％～22％体积的水，加入0.01％～0.02％体积的外加剂，经搅拌得到。
本发明所述陶粒与山砂的混合物是39％～45％体积的陶粒并混合6～10％体积的山砂，生活废弃或工业生产的聚苯乙烯泡沫颗粒为粒度2～6mm的聚苯乙烯泡沫颗粒。所述陶粒为粒度5～25mm的粘土陶粒。所述山砂为云南产的细度模数为0.1～0.7的特细石英山砂。所述工业废渣为II级及以下的低品质粉煤灰。所述外加剂包括减水剂和发泡剂或者是包括减水剂、发泡剂和憎水剂。减水剂为萘系减水剂或聚羧酸系减水剂。发泡剂为动物蛋白发泡剂。
本发明大量利用生活废弃物以及自身含泥量大、细度模数小、级配差、会严重影响混凝土工作性能的山砂等原料，制作成本低，环保且节约能源。其配方合理，制作方法简单，制得的超轻保温材料混凝土性能优良，强度高，抗渗性能好，施工性能好。
下面结合实施例进一步阐述本发明的内容。
