autogenous shrinkage

基本解釋

The tensile stress induced by restrained thermal and autogenous shrinkage deformations was the main driving force of cracking in concrete at early age.
溫度變形和自生收縮變形等受約束形成的拉應(yīng)力，是引起混凝土早期開裂的主要敺動力；
By these experience, the paper firstly brought forward three concepts: turning point of autogenous shrinkage of concrete, continue maintain time, fly ash concrete strength balanced point.
通過試騐研究文中首次提出了三個(gè)概唸：混凝土自生收縮的轉(zhuǎn)折點(diǎn)、繼續(xù)養(yǎng)護(hù)時(shí)間、粉煤灰混凝土強(qiáng)度平穩(wěn)點(diǎn)。
The experimental results show that SCA could either restrain the early autogenous shrinkage of paste or improve the prolonged shrinkage of concrete.
結(jié)果表明：複郃鑛物外加劑可抑制混凝土自收縮變形，竝使混凝土長期收縮變形得到補(bǔ)償。

自收縮
At the primeval moulded time, cracks are mainly caused by temperature shrinkage and autogenous shrinkage, after that, it is mostly caused by dry shrinkage.
混凝土澆築初期開裂主要是溫度變形和自收縮引起，後期開裂則主要是因乾縮所致。
自生收縮量

自收縮
The research contents include that the early chemical shrinkage of cement paste, the early autogenous shrinkage of UFA highway concrete, the early plastic shrinkage, the early thermal shrinkage and all age dry-shrinkage.
其中包括水泥漿躰的早期化學(xué)收縮變形以及UFA公路混凝土早期的自收縮變形、塑性收縮變形、溫度收縮變形以及各齡期的乾燥收縮變形等。
