Concrete formwork manufactured by utilizing waste glass fiber powder and manufacturing method of concrete formwork
The invention provides a concrete formwork manufactured by waste glass fiber powder and a manufacturing method thereof, the concrete formwork comprises a base material and an auxiliary material, the base material comprises the following raw materials by weight: 10-30% of cement, 5-20% of fly ash, 10-50% of waste glass fiber, 5-30% of tailing sand, and 10-30% of water; the auxiliary material is composed of a retarder, a water reducing agent and a reinforcing agent, the retarder accounts for 0-2.5 permillage of the weight of the base material, the water reducing agent accounts for 0-5% of the weight of the base material, and the reinforcing agent accounts for 0-1.5 permillage of the weight of the base material; the preparation method mainly comprises the following steps: weighing the raw materials in percentage by weight, stirring to prepare mortar, adding the waste glass fibers into the mortar to prepare concrete, vibrating or extruding the concrete in a mold, and curing and demolding. The waste glass fibers are utilized, and the prepared concrete formwork has good compression resistance and fracture resistance, can be used as a non-dismantling formwork, and is low in cost and high in economic benefit.
本发明提供一种利用废弃玻璃纤维粉制作的混凝土模板及其制作方法，所述混凝土模板包括基础料和辅料，基础料由以下重量百分比原料组成：水泥10—30％，粉煤灰5—20％，废弃玻璃纤维10—50％，尾矿砂5—30％，水10—30％；辅料由缓凝剂、减水剂和增强剂组成，其中,缓凝剂占基础料重量的0—2.5‰,减水剂占基础料重量的0—5％，增强剂占基础料重量的0—1.5‰；制备方法主要包括按重量百分比称量原料，搅拌制砂浆，向砂浆内填加废弃玻璃纤维制备混凝土，在模具内将混凝土振捣或挤压成型，养护脱模。将废弃玻璃纤维废物利用，制备的混凝土模板具有很好的抗压、抗折性能，而且可作为免拆模板使用，成本低，经济效益高。
