High-toughness inorganic carbonized joint filling material and application thereof
The invention relates to the technical field of joint filling materials, in particular to a high-toughness inorganic carbonized joint filling material and application thereof. Comprising the following components in parts by weight: 40-60 parts of a carbonized cementing material, 3-9 parts of white cement, 5-20 parts of fly ash, 2-8 parts of gypsum, 20-40 parts of an aggregate line byproduct, 3-8 parts of rubber particles, 1.5-6 parts of a water-based adhesive, 4-10 parts of fibers, 10-20 parts of mixing water and 0.08-1.2 parts of a water reducing agent. According to the carbonized joint filling material, the carbonized cementing material is adopted as a main base material in advance, stable carbonate is generated according to the air hardening principle of the carbonized cementing material and is filled in pores in the material, so that the joint filling material has a more compact microstructure and can well cope with various kinds of erosion in the natural environment, and the service life of the joint filling material is prolonged. The long-term stability and the service life of the joint filling material are improved; through the synergistic effect of the rubber particles and the fibers, the fracture resistance of the joint filling material is greatly improved, meanwhile, the volume change caused by thermal expansion and cold contraction between large plates is perfectly dealt with, and the joint filling material has good mechanical properties and is not prone to fracture.
本发明涉及填缝材料技术领域，具体涉及一种高韧无机碳化填缝材料及其应用，包括按重量份数计的如下组分：碳化胶凝材料40‑60份、白水泥3‑9份、粉煤灰5‑20份、石膏2‑8份、骨料线副产物20‑40份、橡胶微粒3～8份、水性胶黏剂1.5‑6份、纤维4‑10份、拌和水10‑20份、减水剂0.08‑1.2份。本发明的碳化填缝材料先进性地采用碳化胶凝材料作为主要基材，利用其气硬性原理生成稳定的碳酸盐填充于材料内部的孔隙中，使得填缝材料具有更致密的微观结构，能较好地应对自然环境中的各类侵蚀，提高填缝材料的长期稳定性和使用寿命；通过橡胶微粒与纤维协同作用，大幅提升填缝材料抗折性能，同时完美应对大板间热胀冷缩带来的体积变化，使得填缝材料具有良好的力学性能，且不易断裂。
