摘要
研究钢纤维对磷酸镁水泥砂浆流动性、强度、收缩性能及耐磨性能的影响,分析钢纤维增强磷酸镁水泥砂浆的水化及钢纤维作用机理,并探讨该材料在工程应用中应当注意的问题。研究结果表明,掺入钢纤维可显著提高磷酸镁水泥砂浆的强度,降低砂浆的收缩率及提高砂浆的耐磨性能;当钢纤维体积掺量不超过1%时,不会明显降低磷酸镁水泥砂浆的流动性。
The effects of steel fiber on the fluidity, strength, shrinkage and abrasiveness of magnesia phosphate cement mortar were studied; the mortar hydration and functioning mechanism of steel-fiber analyzed; and problems noticeable in the engineering application of the material discussed. The research results show that the steel fiber can improve remarkably the strength of the phosphate cement mortar, reduce its shrinkage and en- hance its abrasiveness. And its fluidity does not decline obviously if the mixing content of steel fiber is below 1.0%.
