Micro-expansion porous aggregate ultra-high performance concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses micro-expansion porous aggregate ultra-high performance concrete and a preparation method thereof. The micro-expansion porous aggregate ultra-high performance concrete is prepared from the following raw materials in parts by weight: 350 to 600 parts of cement, 50 to 100 parts of fly ash, 50 to 100 parts of silica fume, 35 to 60 parts of expanding agent, 800 to 1400 parts of fine aggregate, 100 to 200 parts of steel fiber, 5 to 20 parts of shrinkage reducing agent, 5 to 20 parts of water reducing agent and 90 to 150 parts of water. According to the micro-expansion porous aggregate ultra-high performance concrete disclosed by the invention, the early shrinkage of the concrete is reduced on the premise of slightly influencing the mechanical properties of the concrete.
本发明涉及建筑材料领域，具体公开了一种微膨胀多孔骨料超高性能混凝土及其制备方法，该微膨胀多孔骨料超高性能混凝土原材料组成按重量份为：包括按重量份计的下述组分：水泥350‑600份、粉煤灰50‑100份、硅灰50‑100份、膨胀剂35‑60份、细骨料800‑1400份、钢纤维100‑200份、减缩剂5‑20份、减水剂5‑20份、水90‑150份。本发明的微膨胀多孔骨料超高性能混凝土，在较小影响混凝土力学性能的前提下，减少混凝土早期收缩。
