Description

本发明涉及建筑材料，具体地说是混凝土的新组方及加工方法。
目前在建筑领域、大型高架桥涵等水泥制品领域，常用的碎石混凝土容重一般在2500Kg/M3左右，因而水泥构筑物存在笨重的缺点，在保证结构混凝土力学性能的前提下，减轻泥凝土重量是各使用领域长期追求的目标。
本发明的目的是对上述存在的缺点提供一种重量轻、结构力学性能好并具有抗渗、抗冻等功能的高强轻质碎石混凝土。
本发明的目的是这样实现的：取100份普通硅酸盐水泥，碎石50～250份，粉煤灰提取物漂珠和微珠20～50份，砂10～50份，外加剂0.5～15份，水30～50份，经混合搅拌而成。
本发明与普通混凝土相比，具有耐高温、绝缘、隔热、吸音、耐磨等优点。
主要技术指标：
容重（干）：1570～1700kg/m3
抗压强度：250～400kg/cm2
抗拉强度：22～25kg/cm2
抗折：38～44kg/cm2
弹性模量：2.16～2.57kg×105
钢筋握裹力：元钢 40kg/cm2
螺钢 65kg/cm2
收缩：28d    0.01～0.17mm/m
抗渗：B14    以上
冻融：50次    合格
所用的粉煤灰提取物的漂珠和微珠需过2×2mm筛。外加剂为NNO或A、801、UNF-Ⅱ、NF、EA-L型膨胀剂、U型膨胀剂、SN-Ⅱ、FDN。
实施例：
按重量取100份硅酸盐水泥，碎石50份，粉煤类提取物的漂珠和微珠35份，砂20份，NF0.5份，水50份经混合搅拌均匀制成。
施工要求：
1.由于各地的材料差异在使用前应根据此配比的基本原则进行试配，作必要的调整取得满意试验结果再行使用。
2.认真养护淋水21天（草包覆盖）或蒸气养护，夏季施工严防太阳曝晒。
3.振动成型较重要，可采用12000次/分的高频振动器，但振动时间不宜过长，防止集料分离。
