Self-compacting concrete and preparation method thereof
The invention provides self-compacting concrete and a preparation method thereof, the self-compacting concrete comprises the following components in parts by weight (kg/m < 3 >): 335-365 parts of cement, 105-125 parts of fly ash, 23-26 parts of an expanding agent, 150-180 parts of water, 815-845 parts of sand, 815-845 parts of gravel, 28-31 parts by weight (kg/m < 3 >) of an HNTK-1 viscosity modified material and 11-13.5 parts by weight (kg/m < 3 >) of a PCA-VIII high-performance water reducing agent. According to the self-compacting concrete and the preparation method thereof disclosed by the invention, the problems of insufficient strength and durability of the self-compacting concrete caused by the problems of the ratio of raw materials and a control process in the prior art are solved, and the water permeability and the crack resistance of the self-compacting concrete are improved.
本发明提供了一种自密实混凝土及其制备方法，包括以下组分以及重量份数(kg/m3)：水泥335～365、粉煤灰105～125、膨胀剂23～26、水150～180、砂815～845、碎石815～845，还包括HNTK‑1粘度改性材料和PCA‑VIII高性能减水剂，所述HNTK‑1粘度改性材料的重量份数(kg/m3)为28～31，所述PCA‑VIII高性能减水剂的重量份数(kg/m3)为11～13.5。本发明的自密实混凝土及其制备方法解决了现有技术中因原材料的配比和控制工艺问题所导致的自密实混凝土的强度和耐久性不足的问题，提高了自密实混凝土的渗水性能和抗裂性能。
