extent of shrinkage 中文意思是什麼
extent of shrinkage
解釋
收縮程度-
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。 -
The study on salc includes : 1 ) the study on the harmonization between aeration rate and melts thickly rate ; 2 ) the study and application of the new multi - function composite additive ( nmca ) ; 3 ) the study on the durability of salc ; 4 ) the designation of the structure of new multi - functional unbearing compound wall and fast equipment mold, etc. the results show : the additive can improve the harmonization of the workability and mechanics characteristic of salc to a certain extent ; improve the volume stability of salc under different environment by enhancing the resistance to the freeze and thaw, dry and wet circle and drying shrinkage
在salc的研究方面，主要包括發氣速度和稠化速度的協調性研究、新型多功能復合外加劑的研製、耐久性能的研究以及新型多功能非承重復合墻體結構及其澆注成型的快速組裝模具設計等內容；結果表明：科學合理的引入輔助外加劑在一定程度上使salc材料的工作性及相應物理力學性能得以最佳匹配，增強了salc材料對凍融循環、干濕循環及乾燥收縮的抵抗能力，使salc在不同的環境下均具有較好的體積穩定性。 -
The result shows that, when expansion agent is added, shrinkage can he compensated at some extent and crack can be restrained or reduced effectie1y and then the concrete ageing resistance can he enhanced, and under experiment condition, the appropriate mix content of the expansion agent should be less than 6 %, finally, for compensation shrinkage concrete, the restrictive expansion rete should he the primary index
結果表明，加入膨脹劑能補償部分收縮，有效抑制或減少裂縫的產生，提高混凝土的耐久性；試驗條件下試驗所用膨脹劑的適宜摻量應小於6 % ；對補償收縮混凝土，其限制膨脹率應作為第一性指標。
