主要研究墙体抹面水泥砂浆因温差变化发生微观和宏观裂缝 ,甚至扩展的多发病 ,进而阐述抹面纤维水泥砂浆阻止温差裂缝的机理 ,并说明某种规格 ,而且具有一定量纤维的纤维水泥砂浆是可以减少 ,阻止或消除温差变化引发的裂缝。这是很有经济、技术和实用价值的 The main focus is to study the microscopic and macroscopic cracks of wall surface cement mortar due to temperature changes, and even to expand the number of epidemic, and then elaborated the mechanism of plastering fiber cement mortar to prevent temperature cracks, and explain a certain specification, and fiber cement mortar with a certain amount of fiber is Can reduce, prevent or eliminate cracks caused by temperature changes. This is very economic, technical, and practical.
