砼路面修补材料配方及其使用方法
本发明涉及一种砼路面修补材料配方及其使用方法。
目前,已有一种采用JK24快速修补砼路面的方法,虽然这种方法较常规方法大大加快了修复时间节省了一些维修成本,但仍然无法用于露骨超薄层的修补处理。
本发明的目的是要提供一种砭路面修补材料配方及其使用方法,它不仅有利于砭路面损坏的快速修复而且修复质量好,成本低。
本发明砼路面修补材料配方的特征在于:各组分按以下重量配比配制:水泥:1水:0.3~0.37 砂:2~2.5 高效减水剂:0.008~0.01 硫酸钙型膨胀剂:0.01~0.03 硫酸铝型膨胀剂:0.06~0.09。
本发明修补材料的配方采用水泥作为产生强度的基本成分。加入少量高效减水剂可大大减少水泥石内部存在的毛细孔,而且便于施工操作,在提高密实度的同时实现达到早强高温的目的;加入早期膨胀剂——硫酸钙型膨胀剂的作用就是和普通水泥在早期硬化过程中产生的铝酸三钙反应生成水化硫铝酸钙(钙矾石),这种水化物净增加体积较大(可达150%),因而可显著减少收缩产生的内应力,达到提高密实度和粘结强度的目的。加入硫酸铝型膨胀剂的作用就是克服水泥在中、后期水化过程中新出现的铝酸钙和氢氧化钙所引起的收缩,这样才能保证砼路面修补后长时间体积不变化,增加新老界面之间的粘结力,使砼或砂浆始终保持整体性。
此外较之JK24修补材料配方而言,上述配方中所采用的添加剂不仅用量少,而且价格低廉。
采用本发明砼路面修补材料配方修补砼路面的方法是:
(1)清洗:清除修补地段表面上的粉粒杂质及油污。
(2)待干燥后在修补地段的表面上涂刷涤加剂:其重量配比为:高效减水剂:0.008~0.01;硫酸钙型膨胀剂:0.01~0.03 硫酸铝型膨胀剂:0.06~0.09。
(3)拌料:将修补材料的配方伴匀。
(4)打底:在修补地段表面上涂刷与原砭路面同一水灰比的水泥浆。
(5)将拌匀的修补材料摊铺在修补地段上并压实,刮平。
下面结合实施例对本发明予以具体描述:
