Abstract: The present disclosure discloses a method for compression casting concrete to reduce the amount of cement, including: adopting any existing concrete mix proportion designed for concrete of given strength, mixing the concrete, pouring the concrete into a mould, and compressing the concrete at a given pressure, where 28-day strength of the compacted concrete is increased; gradually reducing the amount of cement while keeping the amounts of other materials unchanged, where 28-day strength of the concrete is gradually reduced until the concrete meets a design index; proportionally reducing amounts of water and cement in a last mix proportion while keeping the amounts of other materials unchanged, where during compression casting of the concrete, discharge of cement paste is gradually reduced until no cement paste is discharged; and compression casting a concrete member according to a final mix proportion.
