Analysis on Prevent Common Quality Problems of Raw Material and High Performance Concrete Countermeasure of High-speed Railway

Abstract

The design of high speed railway and the construction of concrete are carried out by high performance concrete. By analyzing the main raw material technical parameters of high performance concrete and comparing with ordinary concrete, the outstanding quality problems and countermeasures exist in the cement, fly ash, mineral powder and silica fume in the raw materials are put forward, so as to provide reference for reference for the quality of concrete.
