The invention discloses a determination method of a cement concrete mixture water-cement ratio. The method comprises the specific steps that: (1) the concrete mixture is sampled within a detection time limit; (2) after sampling, the concrete mixture sample is subjected to an inhibitory treatment, a sand mixing treatment, and a blast drying treatment; and water content Wc of the concrete mixture sample is calculated; (3) with a lowest water-cement ratio beta of a hydration reaction during the drying process, the concrete mixture sample water content Wc is corrected; concrete mixture sample unilateral water content mw is calculated; and with a concrete mixture sample cementing material total amount mb, the concrete mixture sample water-cement ratio is calculated with a formula that W/B=mw/mb.
