混杂纤维掺率对无熟料再生砂浆力学性能的影响

Effect of mixed fibers dosage on properties of non-clinker mortar

通过粉煤灰和矿渣完全取代水泥,并利用25%的再生砂等量替代天然砂,探究不同纤维不同掺率对无熟料砂浆的力学性能的影响。试验表明:聚丙烯和聚丙烯腈纤维的掺入可显著提高砂浆的抗压和抗折强度,双掺的组合比例对砂浆抗压和抗折强度的影响显著。

Through the replacement of cement with fly ash and slag and the replacement of part of natural sand by recycled sand,the effects of different fiber contents on the performance of nonlonitrile fibers can be significantly increased the flexural strength of mortar,polypropylene and polyacrylonitrile fiber double admixture of mortar compressive strength and flexural strength with the combination of the two have significant differences.
