The present disclosure relates to a ceramic forging method, and belongs to the technical field of ceramic preparation. The ceramic forging method comprises a step of applying an oscillatory pressure to to-be-forged ceramic at a forging temperature to perform forging, In accordance with the ceramic forging method provided by the present disclosures, the deformation capacity and the deformation rate of a ceramic material are improved by changing a deformation mechanism of a ceramic material at the high temperature through oscillatory pressure, such that generation of micro fatigues inside the ceramic material and the deformation process of the material are greatly improved, then the ceramic material can reach the higher deformation rate and the larger deformation amount at lower temperature and pressure, and therefore ceramic forging can be achieved, and the cost is greatly reduced.

The present disclosure discloses a novel magnesium phosphate-alkali activated composite cementitious material with rapid hardening, early strength, and high water resistance and a preparation method thereof. The composite cementitious material is a mixture system of a magnesium phosphate cementitious material interweaving and coexisting with an alkali-activated cementitious material, where the alkali-activated cementitious material is prepared by alkali activation of an activatable mineral using a hydration product of a high-alkalinity magnesium phosphate cementitious material prepared from an alkaline hydrophosphate. The composite cementitious material obtained ensures excellent mechanical properties while actively converting part of or all of air-hardening material components into a hydraulic material, so that the problem of poor water resistance of the magnesium phosphate cementitious material can be effectively solved.

Disclosed is a concrete product incorporating rubber aggregate produced by casting under pressure. The concrete product may optionally be cast at 6.9-27.7 MPa for periods of, for example, 24 hours. In one embodiment the rubber aggregate may comprise coarse and/or fine rubber aggregate to replace natural sources of coarse and fine aggregate. Casting under pressure was found to generally improve the performance characteristics of the concrete when compared to corresponding concrete cast without pressure.
