High-crack-resistance concrete for underground engineering and preparation method of high-crack-resistance concrete
The invention relates to the technical field of concrete, and particularly discloses high-crack-resistance concrete for underground engineering and a preparation method of the high-crack-resistance concrete. The high-crack-resistance concrete for underground engineering comprises the following components in parts by mass: 550-600 parts of cement; 80 to 100 parts of fly ash; 2000 to 2200 parts of aggregate; 180 to 200 parts of water; 8-10 parts of a water reducing agent; 5-7 parts of polypropylene fiber; 47 to 51 parts of an auxiliary agent; 1-2 parts of amygdalin; 2-3 parts of mangnolia officinalis polyphenol; and 1 to 2 parts of D-pantoic acid lactone. The anti-cracking agent has the advantage of improving the anti-cracking performance of the concrete.
