【摘要】 大体积混凝土早期的开裂约60%起因于温度收缩。通过优选原材料,优化混凝土配合比,根据不同的气候变化及结构情况组织混凝土的生产和施工,并利用先进、准确、及时的测温系统监测的结果来指导混凝土的养护方法,有效地控制某大学高层住宅基础底板的早期开裂,实现了混凝土的体积稳定性。更多还原

【Abstract】 About 60% of early-age crack of bulk concrete comes from the temperature shrinkage.By raw materials selection,concrete ratios optimization,careful construction according to the climate and the structure,as well as the concrete maintenance under the timely guidance of the advanced and accurate temperature measurement system,the early-age crack of the baseboard of a high-rise house is effectively controlled and the volume stability of the concrete is realized.更多还原
