CRACK RESISTANCE OF HIGH-PERFORMANCE CONCRETE FOR BULK MASS AND THIN-WALL CONSTRUCTION

摘要

The durability of concrete is the key influencing factor for an effective and safe performance of buildings. How to solve the crack problem of hydraulic concrete structure induced by various shrinkages is the emphasis and difficulty in the research of crack control. In this paper, a systematic study was conducted on different mix ratios of high-performance concrete which satisfy the requirements of durability and crack resistance for the construction of a large-scale concrete launder in South-to-North water diversion project.
