Novel foam concrete and preparation method thereof
The invention discloses novel foam concrete and a preparation method thereof, and belongs to the technical field of concrete materials. Iron tailing sand, pumice stone and polypropylene fibers are used for preparation. Industrial wastes can be reduced by using the iron tailing powder; a large amount of pumice is stored in northern areas; meanwhile, the preparation process provided by the inventionmainly solves the problems of low compressive strength, easiness in cracking and the like of the foam concrete, the heat conductivity coefficient is not reduced and the water absorption of the concrete is controlled while the compressive strength of the foam concrete is improved, and the novel foam concrete meets the requirements on performance indexes such as quality, strength, heat conductivitycoefficient, water absorption and the like at present.
本发明公开了一种新型泡沫混凝土及其制备方法，属于混凝土材料技术领域。利用铁尾矿砂、浮石、聚丙烯纤维进行制备，铁尾矿粉的使用可减少工业废料，北方地区有大量的浮石贮存量，与此同时，本发明提出的制备工艺，主要解决泡沫混凝土抗压强度较低、易开裂等问题，并在提高其抗压强度的同时不降低导热系数并控制混凝土的吸水性，这一新型泡沫混凝土符合当下对质量、强度、导热系数、吸水性等性能指标的要求。
