The invention relates to a method for analyzing the ratio of fresh concrete by a microwave rapid drying-dry screening method, which comprises the following steps of: separating coarse aggregate, fine aggregate, fine powder and a cementing material in the fresh concrete by the microwave rapid drying-dry screening method, and calculating the ratio of the fresh concrete according to a water quantity correction coefficient, a gravel aggregate correction coefficient and an influence coefficient of the fine powder in the aggregate on the cementing material. And sampling the uniformity correction coefficient, and calculating the dosage ratio of the water, the cementing material and the gravel aggregate in the fresh concrete. The water consumption, the cementing material consumption, the sand consumption and the stone consumption of fresh concrete can be rapidly and accurately measured within 2-3 hours through a microwave rapid drying method and a dry screening method in combination with correction coefficients of di
