Feasibility study on usage of fly-ash in pit supportting
Feasibility of fly ash substituted for sand and cement in shortcreting is studied based on a lot of laboratory tests,as well as the main influence factors and rules of compressive strength of fly ash concrete are also discussed.Finally,the optimal recipes of fly ash applied to shortcreting concrete are decided by practice tests.
