Pumice concrete after being close - grained and molding is not sensitive to maintaining conditions, and this idiosyncrasy can predigest maintaining measures and reduce lacuna
浮石混凝土在密實成型后,其凝結硬化過程中對于濕養護的敏感性較小,這有利於簡化施工養護措施和減少早期混凝土缺陷的產生。If the surface is covered or watered after casting of concrete, the influence resulted from change of environmental temperature and relative humidity on concrete will decrease to some extent. then the shrinkage stress will also decrease and the probability of cracking will be reduced as well
混凝土澆注完后對表面進行覆蓋或澆水養護,可以很大程度上地減少外界溫濕度變化對混凝土內部的影響,減小了混凝土的收縮應力,從而降低混凝土開裂的可能性。Cover water conservation use, average temperatures above + 5 c using natural conditions, the use of appropriate materials on the concrete surface to be covered and watered, in the concrete cement hydration within a certain period of time required to maintain the proper temperature and humidity conditions
採用覆蓋澆水養護,利用平均氣溫高於5的自然條件,用適當的材料對混凝土表面加以覆蓋並澆水,使混凝土在一定的時間內保持水泥水化作用所需要的適當溫度和濕度條件For the concrete which losing water is little at early - age, strengthen curing, the strength of concrete will be compensated
對早期失水較少的混凝土,加強濕養護,混凝土強度能得到較大的補償。It is very important for reducing and compensating concrete shrinkage and preventing cracks forming to construction and curing
施工和養護對混凝土抗裂防滲性能有重要影響;對于復合抗裂防水高性能混凝土,濕養護時間不宜低於14天。Enlarging concrete section, enveloping iron and strengthening with carbon fiber sheet are the widely - used methods to strengthen concrete column under axial compression, although these methods have their respective defects : wet - work in construction sit, long time for curing and deformation of appearance, the aging of pouring compounds and so on
目前對軸心受壓混凝土構件而言,常用的加固方法有混凝土加大截面法、外包鋼加固法、碳纖維布加固法等。而這些方法各有其缺陷,如現場濕作業問題、養護及外觀問題、灌漿材料或粘接劑的老化問題等。Humidity control in cement concrete standard curing box and standard curing room
水泥混凝土標準養護箱和標準養護室中的濕度控制Abstract : this paper presents the effect of curing to the strength of concrete from the aspects of curing humility, temperature and the treatment of wetting heat, etc. furthermore, the main points in controlling the construction curing are given as well
文摘:從養護濕度、溫度和濕熱處理等方面闡述了養護對混凝土強度的影響,並對施工養護控制要點進行了說明。It provided the reference to improve the anti - cracking capability of high strength and high performance concrete from the point of view of constructional technology and curing requirement. the result shows that the more the binder material or sand rate, the more serious the shrinkage cracking
最後運用該軟體分析在外界溫濕度變化以及不同養護條件下,混凝土內部的溫濕度變化規律及其由此引起的溫度應力和濕度應力,為從施工養護方法上改善高強高性能混凝土抗裂性能提供參考。分享友人
