| dc.title | The structural behavior of steel reinforced slag-fly ash based geopolymer concrete slab | en_US |
| dcterms.abstract | This project aims to investigate the structural behavior of steel reinforced geopolymer concrete slab. Ordinary Portland Concrete (OPC) has become the most mature and dominant material used for construction. Its high compressive strength, proper workability, good durability and relatively low price are all characteristics praised in construction practice. However, there are several problems of OPC with the main disadvantage as a significant contributor for the greenhouse gas. Geopolymer concrete (GPC) is a relative new material, which uses industrial byproducts such as slag and fly ash to replace 100% of cement. This project consisted of experimental and analytical study on the material mechanical property and structural behavior of GPC slabs. The main experiments consisted two parts: pull-out test performed on both OPC and GPC specimen; slab bending test. Firstly, 24 specimens were prepared to conduct the pull-out test to investigate the bond-slip behavior between GPC and steel bar. Secondly, two steel reinforced OPC slabs and two steel reinforced GPC slabs were performed to study the flexural behavior by four-point bending flexural test. The test results suggested that structural behavior of GPC was similar with that of OPC and the practice codes (GB 50010-2002 and ACI 318) were available to theoretical analysis and design of geopolymer concrete. | en_US |
