Stalk concrete block was made of compressed wheat stalk brick and hollow concrete block. Experimental study on heat preservation performance of stalk concrete block and stalk concrete block was carried out. Average heat transfer coefficient of experimental wall made by hollow concrete block is 1.57 W/m².K and stalk concrete block is 1.08W/m².K. Performance of moisture transfer of compressed wheat stalk brick was acquired by using thermostatic and humidistat chamber. Profile of humidity absorption and release was also acquired. The maximum moisture content of compressed wheat stalk brick is 8.85 %. Relative humidity in certain space can be controlled within 50 % -65%.
