Study on the Workability of High Performance Concrete Mixture with Compound Mineral Admixtures

Abstract:

Several compound mineral admixtures, such as steel slag powder, granulated blast furnace slag powder and silica fume, are mixed with proper proportion to improve the workability of High Performance Concrete（HPC）. Through the orthogonal experiment, workability of HPC is analyzed on water-binder ratio, sand ratio, the amount of superplasticizer and the amount of compound mineral admixtures. Results show that: workability of HPC was significantly effected by the amount of naphthalene sulphonate water-reducing admixture and water-binder ratio, the amount of compound mineral admixtures and sand ratio are impact factors on the workability in a certain extent.
