在LHLP环境下半浸泡1个月时，溶液在试件表面的上升高度与浸泡24 h

When immersed in LHLP environment for half a month, the rising height of the solution on the surface of the specimen is the same as that of immersion for 24 h, and no obvious crystal precipitation is seen. After half immersion for 3 months, it was found that the mortar specimen exposed to the air had expansion cracks on the side adjacent to the molding surface, and the cracks extended to the opposite direction of the molding surface. The water-to-binder ratio of the forming surface is the largest, but it remains intact under the action of high-concentration salt erosion.

After half soaking for one month in lhlp environment, the rising height of the solution on the surface of the specimen is the same as that after soaking for 24 hours, and there is no obvious crystal precipitation. Cracks are found on the side of the test piece extending in the opposite direction to the forming surface when it is immersed in the air for 3 months. The water binder ratio of the molding surface is the largest, but it remains intact under the action of high concentration salt erosion.
