Abstract
In order to alleviate the increasing shortage of excellent mountain sand resources, method which sand mixed limestone powder instead of excellent mountain with natrual medi-sand is used, at the same time, taking break stone replace of pebble, and making small break stone and big break stone at the ratio of 3:7 to fabricate the C35~C60 pumping concrete for bridge with high properties. Combing with the example of Wu Song Bridge, C35~C60 pumping concrete with high strength and high properties application technology mixed by break stone and limestone powder double-doping technology was studied. By the optimization design of bridge-like concrete mix proportion, C35~C60 pumping concrete was mixed. Providing a route for high strength pumping concrete mixed by using Jinlin resources.
