autogenous curing 中文意思是什麼
-
After bfs is put into high strength superplasticized expansive concrete ( substituted for cement ), autogenous shrinkage does n ' t appear in 1 day standard curing, and e2 in 14 day ' s age is higher than that of high strength superplasticized expansive concrete without bfs in the same age
高強流態膨脹混凝土摻入磨細礦渣（等量替代水泥）后，標準養護1天未出現自收縮， 14天的限制膨脹率明顯高於未摻磨細礦渣的高強流態膨脹混凝土的對應值。 -
This paper establishes a model simulating dam actual placing process and considering the non - continuity of initial temperature on the boundary of new and old concrete, daily air temperature change, concrete - placing temperature, hydration heat, heat insulation on boundary, water - storing process, placing intermission and curing with water. the calculation of stress field considers the concrete weight, static water pressure, thermal stress, different autogenous volume change between rcc and normal concrete, change of elastic modulus of concrete with age and creep action
考慮了乞今最為全面的初始條件和邊界條件，包括模擬壩體的實際升程過程，考慮了新老混凝土接觸面上的初始溫度不連續，逐日的氣溫變化，混凝土的入倉溫度，水化熱溫升，邊界保溫，水庫蓄水過程，澆築間歇以及灑水養生等因素；應力場的計算考慮了混凝土的自重，靜水壓力，溫度應力，常態混凝土與碾壓混凝土不同的自生體積變形，混凝土的彈性模量隨齡期的變化以及徐變的作用。 -
From the research on hpec we can know that expansion property of high strength superplasticized expansive concrete shows obvious particularity compared with ordinary expansive concrete. when bfs is not put in, high strength superplasticized expansive concrete shows autogenous shrinkage in 1 day standard curing. and in 14 day ' s age e2 is less than half of middle strength superplasticized expansive concrete ' s with same csa dosage, and this shows expansion effect is confined more
對hpec混凝土的研究發現，與普通膨脹混凝土相比，高強流態膨脹混凝土的膨脹性能表現出明顯的特殊性，在不摻超細礦物質摻合料（磨細礦渣）時，高強流態膨脹混凝土標準養護1天時出現自收縮， 14天時其限制膨脹率不到相同csa摻量的中強流態膨脹混凝土限制膨脹率的一半，表現為膨脹效應受到更大限制。
