Efficient fiber concrete preparation process
The invention relates to an efficient fiber concrete preparation process. The preparation process of the high-efficiency fiber concrete comprises the following steps: S1, uniformly stirring cement, sand, stones and fly ash to obtain a concrete premix; and S2, adding the infiltrated modified lignocellulose fiber, polypropylene fiber, a polycarboxylic acid high-efficiency water reducing agent, an organic silicon defoaming agent and water accounting for 90% of the total mass of the water into the concrete premix, uniformly stirring, then adding steel slag and the rest 10% of water, and mixing to obtain the high-efficiency fiber concrete. According to the scheme provided by the invention, the flowability of the concrete can be improved, the concrete is easier to pour and pump, the surface of the hardened concrete base material is smooth, and the mechanical property and durability of the concrete can be improved.
本申请涉及一种高效纤维混凝土制备工艺。该高效纤维混凝土的制备工艺包括以下步骤：S1、取水泥、砂子、石子和粉煤灰搅拌均匀，获得混凝土预混料；S2、向混凝土预混料中加入浸润的改性木质纤维素纤维、聚丙烯纤维、聚羧酸高效减水剂、有机硅消泡剂和水总质量的90％的水搅拌均匀，然后加入钢渣和剩余的10％水混合得到高效纤维混凝土。本申请提供的方案，能够改善混凝土的流动性，使混凝土更容易浇筑和泵送，还能够使得混凝土基材硬化后表面平滑，有助于改善混凝土的力学性能和耐久性。
