High-strength concrete with micro-expansion performance and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses high-strength concrete with micro-expansion performance and a preparation method of the high-strength concrete. The invention discloses high-strength concrete with micro-expansion performance. The high-strength concrete comprises the following components in parts by mass: 100 parts of water; 315 to 317 parts of cement; 35 to 36 parts of fly ash; 1180 to 1200 parts of aggregate; 5.8 to 8.2 parts of a modified expansion auxiliary agent; 2-3 parts of a water reducing agent; the modified expansion auxiliary agent is prepared from a sulphoaluminate expanding agent, calcium carbonate whiskers and polyethylene glycol. The method has the advantage that the strength of the concrete is further improved.
本发明涉及混凝土技术领域，具体公开了一种具有微膨胀性能的高强度混凝土及其制备方法。具有微膨胀性能的高强度混凝土，包括以下质量份数的组分：水100份；水泥315‑317份；粉煤灰35‑36份；骨料1180‑1200份；改性膨胀助剂5.8‑8.2份；减水剂2‑3份；改性膨胀助剂由硫铝酸盐膨胀剂、碳酸钙晶须、聚乙二醇制得。本发明具有进一步提高混凝土的强度的优点。
