rapid-hardening concrete 中文意思是什麼
rapid-hardening concrete
解釋
快硬混凝土-
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（大於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（大於或等於4 . 50mpa ） ; （ 2 ）修補混凝土硬化后4h 、 8h抗壓強度大於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。 -
