The research used materials are fast patching concrete 、 ordinary patching concrete and polymer mortar 。 the testing result indicates : ( 1 ) the mechanics properties of the patched concrete has surpassed the rank of c30 concrete 其研究使用材料有快速修補混凝土、普通修補混凝土及聚合物砂漿。試驗結果表明: ( 1 )修補混凝土力學性能指標已超過c30混凝土等級的要求。
At last in actual project carring on the ordinary and fast patching concrete fieldwork test , polymer mortar patching fieldwork test and grouting patching . it results shows that the patching effect is so good as well as simple construction technics and low expense 最后在實際工程現場進行了普通和快速修補混凝土現場試驗、聚合物砂漿修補現場試驗以及注漿修補現場試驗,結果表明修補效果良好、施工工藝簡單、費用較低。
Specially , the axial tensile strength of the interface of the new and old concrete has reached above 2 . 40mpa , greatly surpassing the preconcert goal ( > 1 . 0mpa ) , and its flexural strength also above 5 . 80mpa , having surpassed the preconcert target and the standard request ( 4 . 50mpa ) . ( 2 ) after hardening 4h and 8h the compressive strength of the patched concrete is bigger than 20 mpa , which can satisfy the request of fast patching . ( 3 ) the ych color material , which is mixed into rapid sulfoaluminate cement - concrete patching material , can take better effect and avoid chromatism on the appearance of new - old concrete 特別是新老混凝土界面的軸向抗拉強度已達2 . 40mpa以上,大大超過原定目標(大于1 . 0mpa ) ,其界面抗折強度也在5 . 80mpa以上,也已超過原定指標及規范要求(大于或等于4 . 50mpa ) ; ( 2 )修補混凝土硬化后4h 、 8h抗壓強度大于20mpa ,能滿足快速修補的要求; ( 3 )在快硬硫鋁酸鹽水泥混凝土修補材料中摻入自配的ych調色材料,能較好地起到調色作用,避免新老混凝土表面色差。
