养护方法对高强混凝土强度的影响

Maintenance method effecting on intensity of high?strength concrete

高强混凝土材料用量大 ,其水化速度取决于周围环境的温湿度 ,影响混凝土强度的增长。将高强混凝土试件放入标准养护水中、盖草帘、包塑料薄膜、空气中和涂养护剂六种不同环境中 ,通过试验和分析比较可知 ,养护条件好 ,混凝土强度早期增长速度就快 ,抗碳化能力就强 ,因此要加强高强混凝土早期养护。

High?strength concrete requires quantities of gelatinous materials and it's water solution speed that effect strength of concrete intensity, depends on temperature and humidity of surroundings, high?concrete is placed standard maintenance method, water, grass, plastics, cloth, air and deep maintaining agent. Through test, analysis and compare, if the maintenance condition is good, intensity and spring intensity of concrete are stengthened quickly in early stage and it's resistance carbonization capacity is strong. So early stage maintenance of high?strength concrete, requires strengthing.
