hydration heat

基本解釋

The early cracking of concrete is usually caused by dry shrinkage, autogenous shrinkage of cement hydration and thermal-strain by hydration heat of cement.
混凝土的早期開裂主要是由于混凝土失水所產(chǎn)生的干燥收縮、水泥水化所產(chǎn)生的混凝土自收縮以及水泥水化熱所產(chǎn)生的溫度應(yīng)變所引起。
The rate of hydration heat evolution and hydration heat of the PC-CS-A system were tested, and the influence of the composition on the heat of the hydration were analyzed.
測(cè)試了PC-CS-A 復(fù)合體系水泥的水化放熱量及水化放熱速率，分析了組成對(duì)水化放熱行為的影響。
According to the test results of 15 specimens of expansive concrete filled steel tube, study the hydration heat, self-stress and the limit bearing capacity of expansive concrete filled steel tube.
依據(jù)15個(gè)鋼管膨脹混凝土試件的試驗(yàn)情況，研究了鋼管膨脹混凝土的水化熱，自應(yīng)力及破壞荷載。

溫度應(yīng)力
Temperature field & thermal stress of hydration heat in massive pile-cap was simulated and studied based on thermal analysis module of ANSYS,a finite element soft. The simulation result of temperature in the concrete is accord to the monitoring data.
采用ANSYS有限元軟件熱分析模塊對(duì)大體積承臺(tái)水化過(guò)程中的溫度場(chǎng)和溫度應(yīng)力進(jìn)行了模擬研究,混凝土中心溫度變化的模擬結(jié)果與實(shí)測(cè)數(shù)據(jù)反映一致;此外,溫度應(yīng)力最大值出現(xiàn)在基礎(chǔ)底部,且小于混凝土的抗拉應(yīng)力,不會(huì)出現(xiàn)溫度裂縫,這也與同一配比的實(shí)驗(yàn)結(jié)果相符。
