Artificial aggregate and preparation method thereof
The invention relates to the technical field of building materials, in particular to an artificial aggregate and a preparation method thereof, the artificial aggregate comprises the following raw materials: 20-100 parts of an air hardening cementing material, 0-80 parts of an admixture and an activator; the air hardening cementing material is one of a gamma-C2S cementing material and a C3S2 cementing material; the preparation method of the artificial aggregate comprises the steps of raw material mixing, water spraying granulation and carbon dioxide curing. The cementing material taking gamma-C2S as a main mineral phase has lower carbon emission and low energy consumption in the production process, the carbonization activity is high, and the strength of the cementing material can reach the strength of 28d ordinary cement under the 24h accelerated carbonization condition.
本发明涉及建筑材料技术领域，具体涉及一种人造骨料及其制备方法，包括以下原料：20‑100份气硬性胶凝材料、0‑80份掺合料及激发剂；所述气硬性胶凝材料为γ‑C2S胶凝材料或C3S2胶凝材料中的一种；一种人造骨料的制备方法包括原料混合、喷水造粒及二氧化碳养护。本发明以γ‑C2S为主要矿物相的胶凝材料在生产过程中具有更低的碳排放和低能耗，并且碳化活性高，在24h的加速碳化条件下的强度可达到28d普通水泥强度。
