Application of C90 High Performance Concrete Prepared with Crushed Cobblestone on Shaft Engineering

Abstract:

The C90 high performance concrete was prepared with crushed cobblestone, washed riverbed sand, special mineral admixture. The crushed cobblestone was crushed from cobblestone which particle size was larger than 160mm. The crushing quality coefficient of the cobblestone was above 80%. The gradation of the crushed cobblestone must accord with 5-20mm continuous grading. The compressive strength of HPC90 was above 40MPa in 1d and 103.9MPa in 28d. At the same time, HPC90 had good ability in anti-crack, impervious and anti-freezing-thawing performance.
