在图3中，半浸泡24 h时，砂浆的成型面已被溶液全部浸湿，说明盐溶液已

In Figure 3, the molding surface of the mortar has been completely soaked by the solution when it is half-soaked for 24 hours, indicating that the salt solution has penetrated the entire molding surface. This is because the mortar slightly bleeds during the molding process, causing the surface water-cement to be relatively large. , Conservation in the early low-humidity environment led to an increase in the number of connected capillary pores on the surface layer, and the salt solution soaked the entire molding surface under capillary action after entering the test piece.

In Figure 3, when the mortar is half soaked for 24 hours, the forming surface of the mortar has been completely soaked by the solution, indicating that the salt solution has penetrated into the whole forming surface. This is because the surface water cement is relatively large due to slight bleeding of the mortar during the forming process. Curing in the early low humidity environment increases the number of pores connected to the surface. After the salt solution enters the test piece, the whole forming surface is soaked under the action of capillarity.

In Figure 3, the molding surface of the mortar has been completely soaked by the solution after half soaking for 24 hours, which indicates that the salt solution has penetrated into the entire molding surface. This is because the slight bleeding of the mortar in the molding process causes the water-cement ratio of the surface layer to be larger, and the maintenance in the early low humidity environment causes the number of pores connected with the surface layer to increase, and the salt solution soaks the entire molding surface under the capillary action after entering the specimen.
