摘要
采用灌注早强膨胀砂浆,对混凝土板块破损区域进行局部修补,可克服快速修补混凝土只注重早强性能而忽视膨胀粘结和不重视基层性能补强的致命弱点,因此,灌浆法具有良好的适用性。
Using grouting high-early-strength expansive mortar to repair breakage in cement concrete slab can overcome the fatal weak points of only paying attention to the high-early-strength performance of fast mending concrete and ignoring its expansion bonding and reinforcement to base course. So, the fast mending cement concrete slab with grouting method has good applicability.
