[Problem] To provide a chip-based mixture having a composition capable of using a large amount of wood chips and coal ash together to make a new functional material utilizing the features of these wood chips and coal ash. A chip-based mixture comprising a powder composed of cement and non-self-hardening coal ash, water, and wood chips, wherein the amount of non-self-hardening coal ash is 20 to 60% by weight based on the amount of powder. And the water powder ratio of the paste consisting of the powder and water is set so that the paste flow value is 150 to 300 mm, and the amount of the paste added is 0.25 to 0.6 in terms of the volume ratio with respect to the wood chips. It was. Moreover, in the case of self-hardening coal ash, the amount of self-hardening coal ash is 20 to 100% by weight with respect to the amount of powder, and the water / powder ratio of the paste consisting of the powder and water is set to a paste flow value of 150 to It set so that it might be set to 270 mm, and the addition amount of the said paste was set to 0.25-0.6 by the volume ratio with respect to a wood chip.
