Production method of low-viscosity ultrahigh-strength concrete
The invention discloses a production method of low-viscosity ultrahigh-strength concrete. The production method comprises the following steps: 1, selecting raw materials for concrete production; wherein the raw materials comprise the following components in parts by weight: 320 to 450 parts of cement, 300 to 420 parts of stone, 600 to 860 parts of sand, 260 to 400 parts of water, 35 to 50 parts ofa water reducing agent, 95 to 105 parts of fly ash, 42 to 57 parts of basalt, 12 to 25 parts of quartz and 15 to 32 parts of mineral powder, and weighing the raw materials in parts by weight. According to the concrete, the mineral powder, the quartz and the basalt are added, so that the ultrahigh strength of the concrete is effectively improved; the viscosity effect between concrete is reduced byadding the water reducing agent, concrete production is stirred, mixed and conveyed by arranging a stirring and conveying device, the stirring and mixing effect between concrete raw materials is effectively improved, and therefore the structural strength and the use performance are effectively improved.
本发明公开了一种低粘度超高强混凝土的生产方法，所述生产方法包括以下步骤：步骤一：选取混凝土生产制备的原料，原料包括以下重量份的组份：水泥320‑450份、石300‑420份、砂600‑860份、水260‑400份、减水剂35‑50份、粉煤灰95‑105份、玄武岩42‑57份、石英12‑25份和矿石粉15‑32份，并按重量组份称量原料，本发明混凝土通过添加矿石粉、石英以及玄武岩有效提高混凝土的超高强度，减水剂的添加降低混凝土之间的粘度作用，通过设置搅拌输送装置对混凝土生产进行搅拌混合输送，有效提高混凝土原料之间的搅拌混合效果，从而有效提高的结构强度和使用性能。
