Special admixture for self-compacting lightweight aggregate concrete and application thereof
The invention discloses a special admixture for self-compacting lightweight aggregate concrete and application thereof, and belongs to the technical field of concrete. The special admixture for the self-compacting lightweight aggregate concrete comprises the following components in parts by mass: 20-25 parts of a reinforcing component, 45-55 parts of a rheological component and 25-30 parts of an expansion component. The admixture special for the self-compacting lightweight aggregate concrete can ensure the self-compacting filling performance of the concrete in the plastic stage of the concrete, maintain uniform and stable suspension of the lightweight aggregate in mortar, and improve the mechanical property of the concrete and reduce shrinkage cracking in the hardening stage of the concrete.
本发明公开了一种自密实轻骨料混凝土专用掺合料及其应用，属于混凝土技术领域。所述自密实轻骨料混凝土专用掺合料包括以下组分，各组分质量份数如下：增强组分20‑25份，流变组分45‑55份，膨胀组分25‑30份。该自密实轻骨料混凝土专用掺合料在混凝土塑性阶段能够保证混凝土的自密实填充性能，维持轻骨料在砂浆中均匀稳定悬浮，在混凝土硬化阶段提升混凝土力学性能和降低收缩开裂。
