摘　　要：混水泥基自流平材料克服了传统水泥基地坪材料施工速度慢，平整度差以及时常出现的开裂、剥落、起灰等多种缺陷。本文通过正交试验确定自流平砂浆的最优基准配合比为灰集比1：1．5、水灰比0．35、聚羧酸减水剂的掺量为0．15％。胶粉和木质纤维的掺人明显降低了砂浆的压折比，提高了砂浆的韧性和抗开裂能力。Mixed self-leveling material overcome slow construction speed, smoothness, often cracking, flaking, ash and other defects of traditional cement base material. This article determined the optimal reference self-leveling mortar mixture ratio for the ash set ratio 1： 1.5, water cement ratio of 0.35, polycarboxylate superplasticizer dosage is 0.15% through orthogonal test. Rubber and wood fiber decreased the ratio of compressive strength of mortar and improved the mortar toughness and cracking resistance.
