Composite ceramic fiber used in building concrete and preparation method thereof
The invention relates to a composite ceramic fiber used in building concrete and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing SiO2 sol, Al2O3 sol and SiC sol to obtain mixed sol, spinning the mixed sol to obtain gel fibers, and roasting the gel fibers at high temperature to obtain the composite ceramic fiber. The compressive strength of finished cement mortar doped with the composite ceramic fiber and the compressive strength of finished cement mortar doped with the PP fiber on the third day, on the seventh day and on the 28th day are compared, and the compressive strength of the finished cement mortar doped with the composite ceramic fiber is obviously higher than that of the finished cement mortar doped with the PP fiber on the 28thday.
本发明涉及一种用于建筑混凝土中的复合陶瓷纤维及其制备方法。本发明将SiO溶胶、AlO溶胶和SiC溶胶均匀混合制得混合溶胶，然后将混合溶胶纺丝制得凝胶纤维，对凝胶纤维进行高温焙烧制得复合陶瓷纤维。本发明比较了掺复合陶瓷纤维和PP纤维的水泥砂浆成品在3天、7天和28天的抗压强度，在28天时，掺加了复合陶瓷纤维的水泥砂浆成品的抗压强度明显高于掺有的PP纤维水泥砂浆成品。
