High-performance concrete and reinforcement intensive concrete prestressed ring beam construction method
The invention relates to a high-performance concrete and reinforcement intensive concrete prestressed ring beam construction method. The high-performance concrete and reinforcement intensive concrete prestressed ring beam comprises the following components by weight: 280kg of cement, 80kg of fly ash, 48kg of mineral powder, 38kg of an anti-cracking agent, 24kg of a viscosity reducer, 710kg of natural sand, 1065kg of gravel, 7.99 kg of a water reducing agent, 150kg of water and 0.235 kg of cellulose ether. The problem that when the distance between the steel bars is too dense, it can be guaranteed that the difference between the internal temperature and the surface temperature is not large without additionally arranging cooling water pipes, and therefore it is guaranteed that cracking of concrete is effectively controlled is solved.
本发明涉及一种高性能混凝土及钢筋密集型混凝土预应力环梁建造方法，它包括如下重量的组分：水泥280kg、粉煤灰80kg、矿粉48kg、抗裂剂38kg、降黏剂24kg、天然砂710kg、碎石1065kg、减水剂7.99kg、水150kg和纤维素醚0.235kg。本发明并解决了在钢筋间距过密时，不用通过增加冷却水管，也能保证内部和表面温度相差不大，从而保证有效控制混凝土的开裂问题。
