Additive for ultrahigh early strength sprayed concrete, application and method
The invention discloses an admixture for ultrahigh early strength sprayed concrete, application and a method, and belongs to the technical field of building materials. The invention relates to a sulfur-containing alkaline peroxide composite material which comprises a first component and a second component, the first component is a sulfur-containing alkaline peroxide, the second component is a reducing agent, and the sulfur-containing alkaline peroxide accounts for 8-15 parts by mass, and the reducing agent accounts for 0.5-4 parts by mass. The admixture has the advantages that the materials are simple and easy to obtain, calcination, powder treatment and the like are not needed, and when the admixture is applied to sprayed concrete, the setting time and the initial strength of the sprayed concrete are obviously improved.
本发明公开了一种用于超高早强喷射混凝土的外加剂、应用及方法，属于建筑材料的技术领域。其包括第一组分和第二组分，所述第一组分为含硫的碱性过氧化物，所述第二组分为还原剂，按质量份数计，所述含硫的碱性过氧化物为8～15份，所述还原剂为0.5～4份。本发明的外加剂具有材料简单易得、无需煅烧、粉末等处理，应用于喷射混凝土时，对其凝结时间和初期强度均有明显的改善。
