Concrete composite admixture and preparation method thereof
The invention relates to a concrete composite admixture and a preparation method thereof. The concrete composite admixture is prepared from the following components in percentage by mass: 40%-60% of CaO, 2.0%-6.0% of SO3, 18%-28% of SiO2, 10%-18% of Al2O3 and 3.0%-7.0% of MgO. The invention relates to a concrete composite admixture and a preparation method thereof. A concept of an alkalinity coefficient is introduced in a configuration process; based on chemical components, functional excitation components suitable for various concrete composite admixtures are matched and prepared, such that the performances of various admixtures are completely excited, the CaO content, the SO3 content and the alkalinity coefficient of the mixed composite admixture are supplemented in a targeted manner, the workability and the durability of the concrete are improved, and the industrial solid waste is widely and effectively utilized.
本发明的一种混凝土复合掺合料极其制备方法由以下质量百分比的组分构成：CaO含量40％‑60％，SO含量2.0％‑6.0％，SiO含量18％‑28％，AlO含量10％‑18％，MgO含量3.0％‑7.0％。本发明的一种混凝土复合掺合料及其制备方法，在配置工艺中引人碱度系数的概念，以化学组分为依据，配合配置适用于各种混凝土复合掺合料的功能性激发组分，使各种掺合料的性能得到充分激发，有针对性的补充混合后复合掺合料CaO含量、SO含量和碱度系数，提高混凝土的工作性和耐久性，更广泛有效地利用工业固废。
