Concrete capable of reducing underground pipe gallery wallboard cracks
The invention provides concrete capable of reducing underground pipe gallery wallboard cracks, which is composed of cement, fly ash, coarse aggregate, fine aggregate, an additive, an expanding agent and water. Per cubic meter of the concrete contains 240 kg of cement, 130 kg of fly ash, 1052 kg of coarse aggregate, 793 kg of fine aggregate, 8.7 kg of additive, 22.4 kg of expanding agent and 153 kg of water. The problem that cracks are easily generated on the wall surface of the underground pipe gallery wallboard when the existing concrete with a common mix proportion is used for coating the wall surface of the underground pipe gallery wallboard is solved.
本发明提供了一种可减少地下管廊墙板裂缝的混凝土，由水泥、粉煤灰、粗集料、细集料、外加剂、膨胀剂和水组成，每立方米的混凝土含有水泥240kg、粉煤灰130kg、粗集料1052kg、细集料793kg、外加剂8.7kg、膨胀剂22.4kg和水153kg。本发明解决了现有的普通配合比的混凝土用于涂覆地下管廊墙板的墙面容易产生裂缝的问题。
