    [Problem] To provide an additive capable of suppressing the generation of free water from a cement slurry even in a high-temperature environment of 150°C or higher. [Solution] A silica-based additive for suppressing free water in high-temperature, high-pressure environments of 100°C or higher, especially 150-300°C, in a cement slurry for cementing in oil fields and gas fields, wherein the silica-based additive includes an aqueous silica sol containing nanosilica particles having a true density of at least 2.15 g/cm
