Firstly, the objective conditions of sizing have a great influence on the deep curing speed. Such as the construction environment, temperature, and humidity have a relatively large impact on the curing speed. If the temperature is too low and the humidity is too high, the deep curing will be significantly slower. In addition, there is ventilation at the construction site. If the air circulation is not smooth, it will affect the deep curing. In addition, the design of the glue joint has a great influence on the deep curing. When the width-to-depth ratio of the glue seam is not appropriate or the depth is too deep, deep curing will be slower; in general, deep curing is slightly slower, and there is no quality problem (such as blistering, internal curing cannot be used, etc.). Impact, the national standard stipulates that the curing period of the test piece is 21 days, and the test specimen is equivalent to the sizing thickness in the actual project, which means that the full curing time determined by the national standard takes 21 days, and the curing time of our reaction is far less than 21 days (usually more than 5-7 days is reflected as slow-drying); In addition, we believe that sealant curing too fast is not good for long-term use, because curing too fast is not conducive to releasing stress caused by temperature during curing. Hidden danger. If the concrete curing time is limited, if it is too fast, it will lead to stress concentration and cracking.
