(57) Provided are an ecological artificial reef concrete using multiple solid wastes and a preparation method therefor. The concrete comprises the following preparation raw materials in parts by weight: 1420-1598 parts of aggregate, 555-657 parts of fine material, 1-5 parts of water reducing agent, and 164-197 parts of water. The aggregate comprises a natural aggregate and/or a recycled aggregate, the mass percentage of the recycled aggregate in the aggregate is 0-100%, and the recycled aggregate is prepared from a construction waste; the fine material comprises cement or a mixture of cement and oyster shell powder, and the mass percentage of the oyster shell powder in the mixture of cement and oyster shell powder is less than or equal to 40%; and the recycled aggregate and the oyster shell powder are not equal to 0 at the same time. In the concrete, the cement is partially replaced with the oyster shell powder, thereby reducing the alkalinity of the concrete, and avoiding the influence of artificial reef on the living environment o[ marine organisms.
