High-strength fine stone self-compacting concrete and fine stone screening device thereof
The invention discloses high-strength fine stone self-compacting concrete. The concrete comprises 400-470 Kg/m<3> of cement, 100-180 Kg/m<3> of mineral coal cinder, 50-70 Kg/m<3> of fly ash, 560-720 Kg/m<3> of gravel, 960-1100 Kg/m<3> of broken stones, 145-190 Kg/m<3> of water and 9-13.5 Kg/m<3> of a water reducing agent, the water-binder ratio is 0.24-0.28, and the sand ratio is 0.38-0.42, and the self-compacting concrete has good filling performance and gap trafficability. The invention further discloses a fine stone screening device of the high-strength fine stone self-compacting concrete.The device comprises an underframe mechanism with a frame structure, a broken stone screening mechanism is arranged above the underframe mechanism, the underframe mechanism is elastically connected with the broken stone screening mechanism through an elastic connecting mechanism, a plurality of vibration devices are arranged at the bottom surface of the broken stone screening mechanism to generatevibration force in different directions, and screens with different grid hole diameters are arranged in the broken stone screening mechanism to fully separate broken stones with different particle sizes.
本发明公开一种高强细石自密实混凝土，其包括水泥、矿煤渣、粉煤灰、砂砾、碎石、水以及减水剂，其中水泥含量为400‑470Kg/m、矿渣粉含量为100‑180Kg/m、粉煤灰含量为50‑70Kg/m、砂砾含量为560‑720Kg/m、碎石含量为960‑1100Kg/m、水的含量为145‑190Kg/m、减水剂含量为9‑13.5Kg/m，水胶比为0.24‑0.28，砂率为0.38‑0.42，能够使自密实混凝土具有良好的填充性能和间隙通过性。本发明还公开了一种高强细石自密实混凝土的细石筛分装置，包括框架结构的底架机构，底架机构上方设有碎石筛分机构，底架机构与碎石筛分机构之间通过弹性连接机构弹性相连，碎石筛分机构底面设有若干个振动装置产生不同方向的振动力，碎石筛分机构内部设有不同网格孔孔径的筛网将不同粒径的碎石充分分离。
