Low-viscosity high-strength concrete
The invention relates to the field of preparation of high-strength concrete, and particularly discloses low-viscosity high-strength concrete. The low-viscosity high-strength concrete is prepared from, by weight, 250-270 parts of cement, 167-190 parts of water, 800-890 parts of machine-made sand, 880-900 parts of gravel, 80-100 parts of mineral powder, 110-130 parts of fly ash and 8-12 parts of additives, I-grade fly ash is selected as the fly ash, the specific surface area of the fly ash is 400-1200 m < 2 >/kg, and the specific surface area of the mineral powder is 550-850 m < 2 >/kg. The production efficiency of the obtained low-viscosity high-strength concrete is 52.5 m < 3 >/h or above, and the 28d compressive strength is 50 MPa or above.
本申请涉及高强混凝土制备领域，具体公开了一种低粘高强混凝土。所述低粘高强混凝土，按照重量份数计，包括水泥250‑270份，水167‑190份，机制砂800‑890份，碎石880‑900份，矿粉80‑100份，粉煤灰110‑130份，外加剂8‑12份，其中粉煤灰选用为Ⅰ级粉煤灰，且粉煤灰的比表面积为400‑1200m2/kg，矿粉的比表面积为550‑850m2/kg。所得低粘高强混凝土的生产效率在52.5m3/h以上，28d抗压强度在50MPa以上。
