Concrete anti-crack, anti-seepage and anti-corrosion construction material and application thereof
The invention relates to a concrete anti-crack, anti-seepage and corrosion-resistant construction material and application thereof. The concrete anti-crack, anti-seepage and corrosion-resistant construction material comprises the following components in percentage by mass: 35-60% of a modified calcium-magnesium composite expanding agent; 10 to 30% of a waterproof component; 10-20% of an anti-corrosion and rust-inhibiting component; 5-15% of a viscosity reducing component; the preparation method of the modified calcium-magnesium composite expanding agent comprises the following steps: S1, reacting a calcium expanding agent with the specific surface area of 350-500 m < 2 >/kg in a hydrogen fluoride atmosphere to obtain a modified calcium expanding agent with calcium fluoride generated on the surface; s2, mixing the modified calcium expanding agent and the magnesium expanding agent, then stirring and mixing with an epoxy silane solution at the temperature of 30-40 DEG C, drying and grinding to obtain the modified calcium-magnesium composite expanding agent. The calcium fluoride layer is coated with the calcium expanding agent, and the modified calcium expanding agent and the magnesium expanding agent are coated with the epoxy silane solution, so that the early expansion loss can be reduced, the medium-term expansion is increased, the water absorption threshold is increased, the later expansion is avoided, the concrete shrinkage is compensated, and the crack resistance and the structural stability are improved.
本申请涉及混凝土抗裂防渗耐腐蚀施工材料及其应用。混凝土抗裂防渗耐腐蚀施工材料以质量百分比计，包括：改性钙镁复合膨胀剂：35‑60%；防水组分：10‑30%；防腐阻锈组分：10‑20%；降粘组分5‑15%；改性钙镁复合膨胀剂的制备步骤包括：S1：将比表面积350‑500 m2/kg的钙质膨胀剂在氟化氢气氛下反应得到表面生成有氟化钙的改性钙质膨胀剂；S2：将改性钙质膨胀剂和镁质膨胀剂混合，再与环氧硅烷溶液在30‑40℃温度下搅拌混合，烘干，研磨获得改性钙镁复合膨胀剂。本发明通过钙质膨胀剂包覆氟化钙层、环氧硅烷溶液包覆改性钙质膨胀剂和镁质膨胀剂，能够降低早期膨胀损失，增加中期膨胀，提高吸水阈值避免后期膨胀，补偿混凝土收缩，提高抗裂性和结构稳定性。
