Fiber reinforced foam concrete material and preparation process thereof
The invention discloses a fiber-reinforced foam concrete material and a preparation process thereof. The fiber-reinforced foam concrete material comprises water, cement, sand and stone powder, the experimental basic formula ratio of the water to the cement to the sand to the stone powder is 0.48: 1: 0.4: 0.6, wherein the amount of the water is 1523 g, the amount of the cement is 3173 g, the amount of the sand is 1269 g, and the amount of the stone powder is 1900 g; the material further comprises 7.38 g of polypropylene fibers, 7.38 g of glass fibers, 7.36 g of pure white wood fibers, 7.38 g of polyvinyl alcohol fibers, 3.69 g of glass fibers, 3.69 g of polyvinyl alcohol fibers and 40 mL of a foaming agent. According to the present invention, the design is performed according to the existing requirements, and after the polypropylene fiber is added into the concrete material, the breaking strength and the compressive strength of the foam concrete are significantly improved and are respectively improved by 28.9% and 26%, and the apparent density is reduced by 30.2%; by adding the polyvinyl alcohol fiber, the breaking strength and compressive strength of the foam concrete are also obviously improved, and the apparent density is slightly higher than that of polypropylene fiber foam concrete.
本发明公开了一种纤维增强型泡沫混凝土材料及其制备工艺，包括水、水泥、砂子和石粉；水、水泥、砂子、石粉实验基本配方比为0.48：1：0.4：0.6，其中水为1523g、水泥为3173g、砂子为1269g、石粉为1900g；还包括聚丙烯纤维7.38g、玻璃纤维7.38g、纯白木质纤维7.36g、聚乙烯醇纤维7.38g以及玻璃纤维3.69g+聚乙烯醇纤维3.69g、发泡剂40mL；本发明根据现有需求进行设计，在混凝土材料中添加了聚丙烯纤维后，泡沫混凝土抗折强度、抗压强度都显著提高，分别提高了28.9％和26％，表观密度降低了30.2％；添加聚乙烯醇纤维，泡沫混凝土的抗折强度和抗压强度也有明显提高，表观密度比聚丙烯纤维泡沫混凝土略高。
