自養護混凝土於不同環境下之研發與應用

Abstract

混凝土施工最後的步驟就是養護，養護品質的好壞，將對於混凝土之耐久性、強度、體積穩定性等各項性質均有相當程度的影響，現今混凝土，常□有卜作嵐材料，故而更突顯出養護的重要性。 本研究目標為自養護在不同環境下之可行性，在低相對濕度環境下自養護之效能減少養護工期，在高相對濕度環境下取代傳統養護方式；試驗中採用自養護藥劑，進行製作混凝土試體，添加自養護藥劑試體在澆置後比較不同濕養護時間並與傳統養護比較，試驗中藉由量測水分重量損失、試體強度與體積收縮來探討混凝土之自養護行為。

The final step is the construction of concrete conservation, curing-quality good or bad, will be for concrete durability, strength, volume stability, and other properties have considerable influence, now concrete, often mixed with pozzolanic materials, so more highlights the importance of conservation. The objective of this conservation in different contexts since the feasibility, low relative humidity in the environment since the performance of maintenance are reduced curing duration, the higher relative humidity environment to replace traditional curing; self-curing agents used in the test, for fabrication of concrete test body, add the curing agents in the placement of specimens after the curing time to compare the wet compared with the traditional curing, test by measuring the weight loss, the compressive strength and volume contraction to explore the self-curing behavior of concrete.
