@article{(Open Science Index):https://publications.waset.org/pdf/10001295, title = {Early-Age Structural and Thermal Performance of GGBS Concrete}, author = {Kangkang Tang}, country = {}, institution = {}, abstract = {A large amount of blast furnace slag is generated in China. Most ground granulated blast furnace slag (GGBS) however ends up in low-grade applications. Blast furnace slag, ground to an appropriate fineness, can be used as a partial replacement of cementitious material in concrete. The potential for using GGBS in structural concrete, e.g. concrete beams and columns is investigated at Xi’an Jiaotong-Liverpool University (XJTLU). With 50% of CEM I cement replaced with GGBS, peak hydration temperatures determined in a suspended concrete slab reduced by 20%. This beneficiary effect has not been further improved with 70% of CEM I replaced with GGBS. Partial replacement of CEM I with GGBS has a retardation effect on the early-age strength of concrete. More GGBS concrete mixes will be conducted to identify an ‘optimum’ replacement level which will lead to a reduced thermal loading, without significantly compromising the early-age strength of concrete.}, journal = {International Journal of Civil and Environmental Engineering}, volume = {9}, number = {5}, year = {2015}, pages = {570 - 573}, ee = {https://publications.waset.org/pdf/10001295}, url = {https://publications.waset.org/vol/101}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 101, 2015}, }
