Description

本发明涉及建筑材料，具体地说是轻质混凝土制备方法。
目前，在建筑行业、水泥造船业、大型高架桥涵等领域所用的轻质混凝土，一般容重为1800Kg～1900Kg/M3，在保证结构混凝土力学性能的前提下，减轻容重是高层建筑、造桥等领域长期追求的目标。
本发明的目的是提供一种重量轻、结构力学性能发能好，并具有抗渗、抗冻等功能的轻质结构混凝土。
本发明的目的是这样实现的：将100份普通硅酸盐水泥，50～150份陶粒，粉煤灰提取物的漂珠和微珠15～35份，砂10～60份，外加剂0.5～15份，水30～50份，经混合搅拌制成。
本发明所给出的轻质混凝土与普通轻质混凝土相比，具有耐高温、隔热、防火、吸音、抗渗、抗冻等优点。其容量仅为1240～1400kg/M3，各种性能优于普通轻质混凝土。
本发明所说的陶粒为粘土陶粒或粉煤灰陶粒;粉煤灰提取物的漂珠和微珠需过2×2mm筛，其物理性能为体轻、耐高温、绝缘、隔热、吸音、耐磨，且筒压强度为1000～7000kg/cm2。粉煤灰提取物的来源为火电厂或大型沸腾炉。
所说的外加剂为NNO或A、801、UNF-Ⅱ、NF、EA-L型膨胀剂、U型膨胀剂、SN-Ⅱ、FDN。
主要技术指标：
容重（干）：1240～1400kg/m3
抗压强度：250～300kg/cm2
抗拉强度：22～27kg/cm2
抗折：40～47kg/cm2
弹性模量：1.26～1.54kg×105
钢筋握裹力：元钢 38kg/cm2
螺钢 52kg/cm2
收缩：28d    0.01～0.18mm/m
抗渗：B14    以上
冻融：50次    合格
实施例：
按重量取525＃硅酸盐水泥100份，粉煤灰陶粒85份，粉煤灰提取物漂珠和微珠15份，砂40份，NF0.5份，水30份，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。
