Low-carbon environment-friendly ultra-high performance concrete and preparation method thereof
The invention belongs to the field of concrete, and discloses low-carbon environment-friendly ultra-high performance concrete and a preparation method thereof. The low-carbon environment-friendly ultra-high performance concrete is prepared from the following raw materials in parts by weight: 13 to 23 parts of water, 50 to 70 parts of cement, 5 to 15 parts of silica fume, 100 to 138 parts of fine aggregate, 20 to 50 parts of quartz powder, 5 to 12 parts of reinforced fiber, 1 to 5 parts of additive, 0 to 0.5 part of calcium polyacrylate (CPA) and 0 to 0.2 part of silane coupling agent. Compared with the traditional ultra-high performance concrete, the low-carbon environment-friendly ultra-high performance concrete provided by the invention has the advantages that the use amount of cementing materials such as cement, silica fume and the like and the use amount of fibers are greatly reduced, but excellent mechanical properties and durability can still be kept.
本发明属于混凝土领域，公开一种低碳环保型超高性能混凝土及其制备方法。本发明的一种低碳环保型超高性能混凝土，包括以下重量份数的原料：水13‑23份，水泥50‑70份，硅灰5‑15份，细集料100‑138份，石英粉20‑50份，增强纤维5‑12份，外加剂1‑5份，聚丙烯酸钙(CPA)0‑0.5份，硅烷偶联剂0‑0.2份。本发明所提供的一种低碳环保型超高性能混凝土，与传统超高性能混凝土相比，其水泥、硅灰等胶凝材料用量及纤维用量都大幅减少，但依然能够保持优异的力学性能及耐久性能。
