YH—2防裂剂自1986年研制以来,已在全国数千万平方米的抹灰及混凝土工程中应用,使用单位通过使用YH—2防裂剂不仅解决了加气混凝土抹灰长期存在的裂缝、空鼓问题及混凝土施工的表而干缩裂缝问题,而且大大提高了工程质量,降低了成本,取得了显著的经济效益和社会效益,并积累了不少使用YH—2防裂剂的经验。但也存在少数单位由于未按正确方法使用而未取得理想效果。为了帮助用户正确使用YH—2防裂剂,我们特将YH—2防裂剂的适用范围、材料性能、贮存方法、操作工艺及施工注意事项作一系统介绍。 YH-2 anti-cracking agent has been applied in tens of millions of square meters of plastering and concrete projects across the country since it was developed in 1986. The use of YH-2 anti-cracking agent not only solved the long-standing problem of aerated concrete plaster. Cracks, hollowing problems, and shrinkage cracks on the surface of concrete construction have greatly improved project quality, reduced costs, and achieved remarkable economic and social benefits. Many YH-2 anti-cracking agents have been accumulated. experience. However, there are also a few units that have not achieved the desired results because they are not used in the correct way. In order to help the user to correctly use the YH-2 anti-cracking agent, we specifically introduce the application scope, material properties, storage methods, operation technology and construction precautions of the YH-2 anti-cracking agent.
