| dc.description.abstract | 台灣擁有豐富的碳酸鹽類岩石，但台灣對鹼-碳酸鹽反應(ACR)的研究卻不多。本研究利用加拿大化學法(CSA A23.2-26A)普查可能具有ACR活性的粒料，規劃第二次取料的項目，再區分ASTM系統(ASTM C 586、ASTM C 1105、ASTM C 1293)、RILEM系統(RILEM TC 191-ARP-AAR-2、RILEM TC 191-ARP-AAR-5)、加拿大系統(CSA A23.2-26A、CSA A23.2-14A)、模擬中國蒸壓法進行粒料的ACR活性探討及在台灣地區的適用性分析，以微觀分析(SEM、XRD)輔助判別粒料活性，並以LiOH溶液區分粒料的AAR特性。結果顯示，具有ACR活性粒料共14種，其中二種同時具有ASR活性；ASTM及RILEM檢測粒料ACR活性系統均適合於台灣地區使用。綜合試驗結果，提出適用於台灣地區粒料ACR活性檢測的流程為，先以ASTM C 586或RILEM TC 191-ARP-AAR-5試驗法篩選粒料的ACR活性，判定為非活性粒料，可以直接用為混凝土用粒料，若判定具有ACR活性，在使用前應再經ASTM C 1105試驗作最終ACR活性判別，屬非活性方能使用。 | zh_TW |
| dc.description.abstract | There are many carbonate rocks in Taiwan, but less study of alkali-carbonate reaction (ACR) in Taiwan. The research use the Canada chemical method (CSA A23.2-26A) to embryonic exploration the aggregates which may have alkali-carbonate reaction, and plan for second collect the aggregates. We proceed to treat ACR activity of the aggregates and analyze the applicability in Taiwan by the system of ASTM(ASTM C 586、ASTM C 1105、ASTM C 1293)、the system of RILEM(RILEM TC 191-ARP-AAR-2、RILEM TC 191-ARP-AAR-5)、the system of Canada(CSA A23.2-26A、CSA A23.2-14A)、the imitate autoclave method of China. Use micro-analyses(SEM、XRD)to assist identify activity of the aggregate, and use LiOH solution to discriminate AAR characteristic of the aggregate. The result of test show there are fourteen kinds of aggregates have ACR activity, and two kinds among fourteen kinds of aggregates which have ACR activity all have ASR activity. The system of ASTM and RILEM both adaptable to use to identify the aggregates which have ACR in Taiwan. Composite the result of test, and advance the procedure which adaptable to identify the aggregates which have ACR in Taiwan. First, using ASTM C 586 or RILEM TC 191-ARP-AAR-5 to scan for the aggregates if have ACR activity. If the aggregate is identified have no ACR activity, it can direct use in concrete. If the aggregate is identified have ACR activity, it need use ASTM C 1105 to finally identify if have ACR activity, and check it have no ACR activity before used. | en_US |
