工程实践和研究证明,在抹灰砂浆中掺加聚丙烯纤维,是防止水泥砂浆抹面及混凝土中因塑性收缩、干缩、温差等内部应力的作用产生微裂缝的有效手段,而且从确保工程质量、施工便利、兼顾成本及长短期效益等方面考虑,采用聚丙烯纤维砂浆不失为一种良好的施工方案。 Engineering practice and research prove that mixing plaster with plaster in plaster mortar is an effective way to prevent microcracks caused by internal stress such as plastic shrinkage, shrinkage and temperature difference in plastering mortar and concrete, , Construction convenience, taking into account cost and short-term benefits and other considerations, the use of polypropylene fiber mortar after all, a good construction program.
