The early age cracking of concrete is concerned with its thermal expansion properties, which is mainly reflected by the thermal expansion coefficient. Reasonably controlling the coefficient is an effective way of reducing cracks in the early age of concrete. While thermal expansion properties are related to the micro-pore texture characteristics of the concrete. Micro-pore textures of concretes of different mixing ratios and curing time were measured via mercury intrusion porosimetry (MIP), and the thermal expansion coefficient was determined by the comparator. The analysis of test results indicates the correlation between the parameters of micro-pore texture and thermal expansion properties, and also shows a highly positive correlation between the pore area and the thermal expansion coefficient. The results provide a solution for reducing the thermal expansion coefficient, thus controlling the early age cracking.

This article describes an experimental program developed to study the influence of longitudinal prestress on the behaviour of high-strength concrete hollow beams under pure torsion. The pre-cracking, the post-cracking and the ultimate behaviour are analysed. Three tests were carried out on large hollow high-strength concrete beams with similar concrete strength. The variable studied was the level of longitudinal uniform prestress. Some important conclusions on different aspects of the beams’ behaviour are presented. These conclusions, considered important for the design of box bridges, include the influence of the level of prestress in the cracking and ultimate behaviour.
