Method for optimizing formula parameters of volcanic ash, desert sand concrete and concrete

The invention relates to volcanic ash, desert sand concrete and a concrete formula parameter optimization method. The invention is applicable to the technical field of concrete. The technical problem to be solved by the invention is to provide the volcanic ash, desert sand concrete and concrete formula parameter optimization method. According to the technical scheme, the volcanic ash and desert sand concrete is characterized by comprising a cementing material, coarse aggregate, fine aggregate, a water reducing agent and water, the cementing material contains volcanic ash, and the weight ratio of the volcanic ash in the cementing material is 5%-40%; the fine aggregate contains desert sand, and the weight ratio of the desert sand in the fine aggregate is 5%-20%; the content of the cementing material is 350kg/m < 3 >-500kg/m < 3 >; the water-binder ratio of the water to the binding material is 0.450 to 0.525; and the content of the water reducing agent is 0.25%-1.00% of the mass of the cementing material. 本申请涉及一
