环氧树脂混凝土在公路大修工程中的应用

Application of epoxy resin concrete in highway overhaul engineering

随着公路桥梁等交通基础设施使用年限的增加,维修加固工作也日趋繁重,亟需应用优质的修补材料恢复结构性能延长使用寿命。通过环氧树脂混凝土在公路大修工程中的应用,表明环氧树脂混凝土具有凝固时间快、早期强度高、与旧混凝土及金属黏结强度大等优点,在维修加固工程中能大大缩短工期,可用于公路桥梁的紧急维修加固。

With the increasing service life of transportation infrastructure such as highways and bridges,maintenance and reinforcement work is becoming increasingly heavy,and there is an urgent need to apply high-quality repair materials to restore structural performance and extend service life.This project demonstrates the application of epoxy resin concrete in highway overhaul engineering,which has advantages such as fast solidification time,high early strength,and strong bonding with old concrete and metal.It can greatly shorten the construction period in maintenance and reinforcement engineering and can be used for emergency maintenance and reinforcement of bridges.
