hydration variation 中文意思是什麼
hydration variation
解釋
水化變異-
In the paper, not only such factors as reinforcing steel bar, various placing temperature of concrete in case of lift placements, lift thickness, time interval between lifts, the variation of elastic modules of concrete, heat of hydration, the temperature changes of environment but the effect of creep deformation and autogenous volume change on the temperature field and thermal stress field of reinforced concrete face - slab are considered
本論文在分析中,考慮了鋼筋、混凝土分層澆築、入倉溫度、澆築層厚、施工間歇、混凝土彈性模量變化、水化熱發散規律、外界氣溫等因素的變化及混凝土徐變和自生體積變形等因素對面板溫度場和溫度應力的影響。 -
Adopting fd - 1 admixture, c50 concrete can be obtained, which has excellent adaptability for environment temperature ? 5 c ; self - shrinkage of concrete is inevitable, and its variation tendency based on w / c and hydration age, fd - 1 has wonderful inhibition for self - shrinkage, and meanwhile anti - friction property can be promoted
在fd - 1組分對負溫混凝土的耐久性能研究中,認為影響自收縮的主要因素是水灰比和齡期; fd - 1外加劑對水泥自收縮有很好的抑制作用,能夠有效的提高水泥砂漿的耐磨性能。
