Abstract:	目前營建廢棄物處理方式多半是採取填海造路及回填造地等，其中原因主要乃在其對所製成之混凝土強度沒有把握。本文取用營建廢棄物作為再生粗骨材，並分成三種最大粒徑，四種坍度及七組水灰比。從配合比設計開始、試拌、測坍度、製作試體、養護到抗壓強度試驗。其中並測再生粗骨材及所製作混凝土之PH值。由試驗資料統計分析得知，用再生粗骨材所製作混凝土，其抗壓強度皆能符合營建工程之要求，而與一般混凝土強度比較約為其88% 。另外並推導7 天與28 天的強度關係及再生混凝土(再生粗骨材+天然砂)拌合所需用水量檢討與分析。 Form this thesis we take research of garbage from construction in our country .The recycled aggregates and garbage would be used to fill up the low-lying land or the coastal line. So the research of this thesis is to take 7 groups of water-cement ratio and 4 groups of slumps in batch. From the designed recipe, slump test, mixed test, take groups of concrete samples, curing, and compressive strength tests. To understand the statistics data from the experiments we will take PH tests and compressive strength from our concrete samples. The test data demonstrate that the compressive strength of recycled aggregates would be about 88 percent of the strength from general aggregates concrete in the same water-cement ratio. Besides we calculate the relationships from the water-cement ratio and compressive strength of 7days or compressive strength of 28 days.
