Belonging to the technical field of constructional engineering, the invention discloses a cast quartz waste sand concrete, a mortar additive and a use method thereof. The cast quartz waste sand concrete and the mortar additive comprises the following components by mass percentage: 0.17-28% of an alkali aggregate inhibitor, 0.3-6% of concrete fiber, 5-99% of a cementing material and the balance cement. When used for concrete, the use method includes: weighing the additive accounting for 30% of the weight of a cementing material in ordinary sand concrete, then weighing cement accounting for 70%of the weight of the cementing material in ordinary sand concrete, and then sequentially weighing cast quartz waste sand, stones, water and a water reducing agent; pouring the stones, the cast quartzwaste sand, the cement and the additive sequentially into a stirring pot, performing stirring, then adding water and the water reducing agent, and further conducting stirring. When used for mortar, the use method includes: wei
