Micro-expansive concrete and production process thereof
The invention relates to the technical field of building materials, in particular to micro-expansive concrete and a production process thereof. The micro-expansive concrete is prepared from the following raw materials in parts by weight: 260 to 320 parts of cement, 1000 to 1200 parts of stone, 590 to 640 parts of sand, 100 to 120 parts of admixture, 15 to 20 parts of glass fiber, 30 to 40 parts of polypropylene fiber, 13 to 18 parts of aluminum sulfate, 10 to 14 parts of compound expanding agent, 5 to 8 parts of synergistic expanding agent, 7 to 10 parts of water reducing agent, 5 to 8 parts of octylphenol polyoxyethylene ether, 4 to 6 parts of sodium abietate and 180 to 220 parts of water, the synergistic expansion agent and the compound expansion agent cooperate with each other, so that the mechanical meshing force between the expansion agent and cement can be effectively enhanced, the expansion amount of the hardened concrete can also be enhanced, the early plastic shrinkage of the concrete is inhibited, and the anti-cracking effect of the concrete is further improved; in addition, the glass fibers and the polypropylene fibers cooperate with each other, so that the mechanical property of the concrete is effectively improved, and the quality of the concrete is effectively ensured.
本发明涉及建筑材料技术领域，具体为一种微膨胀混凝土及其生产工艺；所述微膨胀混凝土由以下重量份原料组成：260～320份水泥、1000～1200份石子、590～640份砂子、100～120份掺合料、15～20份玻璃纤维、30～40份聚丙烯纤维、13～18份硫酸铝、10～14份复配膨胀剂、5～8份协效膨胀剂、7～10份减水剂、5～8份辛基酚聚氧乙烯醚、4～6份松脂酸钠及180～220份水；本发明中协效膨胀剂与复配膨胀剂之间相互协同，能有效地增强其与水泥之间的机械啮合力，也能增强混凝土硬化后的膨胀量，抑制混凝土的早期塑性收缩，进而提高其防裂效果；另外，玻璃纤维及聚丙烯纤维之间相互协同配合，有效地改善了混凝土的力学性能，有效地保证了其品质。
