Early-strength anti-cracking composite functional additive
The invention discloses an early-strength anti-cracking composite functional additive. The additive comprises the following components in percentage by mass: 85-93% of a composite fiber component; 4-9% of an internal curing agent component; 2-7% of a sepiolite component, wherein the composite fiber component is a mixture of whiskers and synthetic fibers; the component of the internal curing agent is super absorbent resin; the sepiolite component is sedimentary type aluminum-rich sepiolite. The additive can homogenize the internal structure of the cement-based material to a certain extent, meanwhile, cement components in the cement-based material are promoted to be further hydrated, the internal structure of the material is compacted, and the mechanical property and the crack resistance of the material are finally comprehensively improved under the multi-dimensional toughening effect of the composite fiber components. The fracture resistance and compressive strength of different cement-based materials within 1-3 days can be improved by 15-40%. The additive is wide in component source and reasonable in price, can play a role after being added when the cement-based material is mixed and uniformly stirred, and is convenient to use.
本发明公开了一种早强抗裂型复合功能添加剂，该添加剂其组成按质量百分数计如下：复合纤维组分85‑93％；内养护剂组分4‑9％；海泡石组分2‑7％，其中所述复合纤维组分为晶须与合成纤维的混合物；所述内养护剂组分为高吸水性树脂；所述海泡石组分为沉积型富铝海泡石。该添加剂可以一定程度均化水泥基材料的内部结构，同时促进水泥基材料内水泥组分进一步水化，密实材料的内部结构，再加上复合纤维组分的多维增韧作用，最终全面提升材料的力学性能和抗裂性能，能够提升不同水泥基材料1～3d抗折、抗压强度15‑40％。本添加剂的组分来源广泛，价格合理，在水泥基材料拌制时加入，搅拌均匀后即能发挥功效，使用方便。
