[0001] The present invention relates to the field of stone-like permeable bricks, and in particular to a stone-like permeable brick strengthening agent and a preparation method thereof. Background Art

[0002] The stone-like permeable brick is a concrete material with a large stone content made of crushed stones and cement. In order to show the texture of the stone, the amount of cement used is less, resulting in the low strength of the existing stone-like permeable bricks. The existing methods for improving the strength of the stone-like permeable bricks mainly increase the amount of cement. However, once the amount of cement is increased, the texture on the surface of the permeable brick will become blurred, and the texture of the stone cannot be clearly seen, resulting in a relatively poor texture of the material, which is difficult to meet the needs of consumers.
