摘 要:根据普通预拌砂浆的技术性能要求,研究了胶材总量及各组分掺量、机制砂性能、外加剂种类及掺量对机制砂湿拌抹灰砂浆性能的影响,确定了稠度、保水性、可操作时间、强度及施工性能等综合性能优良的M5~M15抹灰砂浆的配合比;提出了机制砂湿拌砂浆中试生产应用过程中简要的质量控制方法。中试生产应用表明,M5~M15湿拌抹灰砂浆的和易性及施工质量良好,墙面均无空鼓开裂现象。
Abstract: The influence of total amount of cementitious material (as well as the ratios of each component), performance of artificial-sand and types and amount of additives on the wet-mixed plastering mortar are studied according to the performance requirements of common ready-mixed mortar. Based on experiments, the optimum mix proportion of M5~M15 plastering mortar with excellent overall properties (mortar consistency, water retention, operable time, compressive strength and workability) is determined. Some simple methods are put forward to control the production and construction quality of plastering mortar. The pilot production and applied results show that M5~M15 wet-mixed plastering mortar has excellent workability and construction quality during the period of construction. Hollow and cracks could not be found on the plaster wall through a long-term verification.
