Non-autoclaved admixture and preparation method thereof
The invention discloses a non-autoclaved admixture and a preparation method thereof, belonging to the technical field of non-autoclaved admixture production. The technical problem to be solved by the invention is that the strength of a precast concrete component is not high. The non-autoclaved admixture is mainly prepared from 100-500 parts by weight of slag powder, 10-100 parts by weight of silica fume and 10-200 parts by weight of fly ash. The preparation method comprises the following steps: firstly, respectively grinding the weighed slag powder, silica fume and fly ash in a ball mill, conducting mixing, performing grinding in a superfine ball mill, and carrying out sorting to obtain the non-autoclaved admixture. The non-autoclaved admixture of the invention is applied to precast concrete components, and can significantly improve the concrete strength, and the high activity index can avoid the link of steam curing of the concrete components in a pressure vessel; the working performance and durability of the concrete are obviously improved; hydration heat is low; and the environment is protected.
一种免蒸压掺合料及其制备方法，它属于免蒸压掺合料生产技术领域。本发明要解决的技术问题为混凝土预制构件强度不高的问题。本发明所述的免蒸压掺合料主要是由矿渣粉、硅灰、粉煤灰制成，其重量份数分别为100～500份的矿渣粉、10～100份的硅灰、10～200份的粉煤灰,首先将称量好的矿渣粉、硅灰、粉煤灰分别置于球磨机中研磨后，再混合后置于超细球磨机中研磨，分选后得到一种免蒸压掺合料。本发明应用于混凝土预制构件，能显著提高混凝土强度，高活性指数能免除混凝土构件在压力容器蒸养的环节；混凝土工作性能和耐久性能显著提高；水化热低；环保。
