Abstract
The invention relates to the technical field of concrete mineral admixtures, and discloses a preparation process of early-strength phosphorus slag-based concrete. The concrete raw materials include the following raw materials by mass per cubic meter: 300-360 kg of cementitious material, 730-804 kg of fine aggregate, 1061-1100 kg of coarse aggregate, 3.0-3.6 kg of admixture, 1.5-1.8 kg of additive, and 158-171 kg of water. A preparation device for pressing the materials into pellets includes a preparation mechanism and a lower hopper connected and installed at the upper end of the preparation mechanism. When a covering member is squeezed, it approaches to fit with the surface of an inner roller shaft, and a mixture stored in the covering member is squeezed into a hemispherical hole to compensate for the gap in the hemispherical hole, thereby ensuring the compaction and integrity of the sphere after molding and reducing rework.
