Water-blocking anti-cracking high-toughness bonding reinforcement repair material and preparation method thereof
The invention discloses a water-blocking anti-cracking high-toughness bonding reinforcement repair material, which is composed of a base material and synthetic fibers, and is characterized in that thebase material comprises the following raw materials in percentage by mass: 25%-40% of cement, 25%-35% of fly ash, 1%-3% of silica fume, 10%-25% of quartz medium sand, 10%-23% of water, 0.2%-1.0% of xanthan gum, 1%-2% of a water repellent, 0.4%-1.0% of attapulgite, 3%-10% of rubber powder and 0.5%-1.2% of a water reducing agent; and the synthetic fibers account for 1-3% of the total volume of thebase material. The water-blocking, anti-cracking and high-toughness bonding, reinforcing and repairing material provided by the invention is green, environment-friendly, non-toxic, harmless, high in chloride ion permeability resistance coefficient and free of corrosion to existing structures, can be used for repairing and reinforcing reinforced concrete, beams, columns, walls and other building structures, and is wide in application range. The ultimate tensile strain is not lower than 5%, the bonding strength is not lower than 1.5 Mpa, the chloride ion penetration resistance grade is larger than the fourth grade, and the impermeability grade is larger than 1.5 MPa.
本发明公开了一种阻水抗裂高韧性粘结加固修补材料，由基础料及合成纤维组成，其特征在于，所述基础料的原料按照质量百分比计算，包括：水泥25%‑40%，粉煤灰25%‑35%，硅灰1%‑3%，石英中砂10%‑25%，水10%‑23%，黄原胶0.2%‑1.0%，憎水剂1%‑2%，凹凸棒土0.4%‑1.0%，胶粉3%‑10%，减水剂0.5%‑1.2%；所述合成纤维占基础料总体积的1%‑3%。本发明提供了一种阻水抗裂高韧性粘结加固修补材料，绿色环保、无毒无害，抗氯离子渗透系数高，对既有结构无腐蚀性作用，可用于钢筋混凝土、梁、柱、墙等建筑结构的修补加固，适用范围广。本发明极限拉应变不低于5%，粘结强度不低于1.5Mpa，抗氯离子渗透等级大于四级，抗渗等级大于1.5MPa。
