Self-compacting concrete additive and subway precast slab track self-compacting concrete
The invention discloses a self-compacting concrete additive and subway precast slab track self-compacting concrete, and belongs to the technical field of building materials. The additive is prepared from the following raw material components in parts by weight: 100 parts of mica powder, 50 to 100 parts of talcum powder, 100 to 250 parts of silica fume, 1 to 2 parts of carboxymethyl cellulose, 20 to 50 parts of propyl benzene rubber powder, 25 to 50 parts of butadiene-styrene rubber powder, 10 to 20 parts of paraffin powder, 20 to 50 parts of lignin fiber, 10 to 20 parts of polypropylene fiber and 10 to 50 parts of triisopropanolamine. By optimizing the composition proportion and the synergistic effect of all the components, the comprehensive performance such as early strength, impact resistance, electrical insulation performance and durability of the concrete is remarkably improved. The additive is not only suitable for subway precast slab track construction, but also can be widely applied to other engineering projects needing high-performance self-compacting concrete, and has high practical value.
本发明公开了一种自密实混凝土添加剂及地铁预制板轨道自密实混凝土，属于建筑材料技术领域。该添加剂，按重量份计，其原料组分包括：云母粉100份、滑石粉50～100份、硅灰100～250份、羧甲基纤维素1～2份、丙苯胶粉20～50份、丁苯胶粉25～50份、石蜡粉10～20份、木质素纤维20～50份、聚丙烯纤维10～20份、三异丙醇胺10～50份。本发明通过优化成分配比和各成分的协同作用，显著提升混凝土的早期强度、抗冲击性、电绝缘性能及耐久性等综合性能。该添加剂不仅适用于地铁预制板轨道施工，也可广泛应用于其他需要高性能自密实混凝土的工程项目中，具有较高的实用价值。
