Abstract
Hydraulic concrete may be subjected to carbonation erosion in nature.After carbonation,the volume of concrete shrinks,and in severe cases,cracks may even occur.Concrete cracking can cause corrosion of inter-nal steel bars in the concrete,further exacerbating the cracks,ultimately leading to structural damage to hy-draulic concrete,greatly affecting the durability of hydraulic concrete.The author conducted carbonation tests on hydraulic concrete specimens with different mix ratios,and obtained the carbonation depth results of hy-draulic concrete with different water cement ratios and water reducing agent dosages at the ages of 4,7,14,and 28 days.The carbonation test results were analyzed,the variation trend of carbonation depth was analyzed to provide research data for the rational design of hydraulic concrete water cement ratio and water reducing agent dosage under carbonization,and further providing a research basis for predicting the lifespan of hydraulic con-crete under carbonization.关键词
