Aiming at severe cold areas, this paper replaces 5% cement and 30% natural gravel with the same amount of ground rice husks and recycled aggregates respectively, and designs a new self-insulating block structure model compared with traditional blocks. This new block is easy to assemble, short construction period and good seismic performance. The 28d splitting strength of concrete and 28d compressive strength of blocks are determined. The results showed that this mate is better than the cracking strength of the block that can act as a MU10 non-load-bearing wall, and the standard test piece is better than ordinary concrete.
