Self-compacting concrete viscosity reducer as well as preparation method, use method and application thereof
The invention provides a self-compacting concrete viscosity reducer as well as a preparation method, a use method and application thereof, and relates to the technical field of concrete admixtures, the self-compacting concrete viscosity reducer comprises a material A and a material B, wherein the material A comprises the following components: saponin powder, glass beads, superfine limestone powder and calcium stearate; and the material B comprises the following components: sodium tripolyphosphate, sodium thiosulfate, a rheological agent and water. The technical problem that the self-compacting concrete with the strength grade of C100 and above cannot be pumped for construction due to high viscosity is solved, and the technical effect that the slump loss resistance, the homogeneity and the mechanical property of the self-compacting concrete are simultaneously improved through synergistic cooperation of all the components is achieved.
本发明提供了一种自密实混凝土降粘剂及其制备方法、使用方法、应用，涉及混凝土外加剂的技术领域，包括A料和B料；其中，A料包括以下组分：皂角粉、玻璃微珠、超细石灰石粉，以及硬脂酸钙；B料包括以下组分：三聚磷酸钠、硫代硫酸钠、流变剂，以及水。本发明解决了C100及以上强度等级的自密实混凝土因粘度大而无法泵送施工的技术问题，达到了各组分协同配合而使自密实混凝土的保坍性能、匀质性以及力学性能得以同时提升的技术效果。
