Multifunctional box culvert pipe gallery concrete and preparation method thereof
The invention discloses a multifunctional box culvert pipe gallery concrete and a preparation method thereof. The multifunctional box culvert pipe gallery concrete is prepared from, by weight, 20-25 parts of cement, 8-12 parts of sand, 9-18 parts of aggregate, 5-8 parts of microbeads, 8-15 parts of fly ash, 12-18 parts of zeolite, 4-6 parts of waterborne resin, 0.6-1.5 parts of an expanding agent,1-3 parts of composite fiber, 0.7-2 parts of a water reducing agent component and 12-20 parts of total water. The self-compacting and working performance of concrete can be obviously improved, meanwhile, the self-curing performance is achieved, and vertical cracking of a large-size, ultra-long and thin-wall concrete gallery body structure can be effectively reduced.
本发明公开了一种多功能箱涵管廊混凝土及其制备方法，按照重量份数计，原料包括水泥20‑25份、砂料8‑12份、骨料9‑18份、微珠5‑8份、粉煤灰8‑15份、沸石12‑18份、水性树脂4‑6份、膨胀剂0.6‑1.5份、复合纤维1‑3份、减水剂组分0.7‑2份、总水量12‑20份。本发明可明显提高混凝土的自密实和工作性能，同时兼具自养护性能，可有效减少大体积、超长薄壁混凝土廊体结构竖向开裂。
