Arbi, K.A. (author), Nedeljkovic, M. (author), Zuo, Y. (author), Grunewald, S. (author), Keulen, A. (author), Ye, G. (author)This paper presents an investigation on workability and strength of geopolymer concrete made of fly ash (FA), blast furnace slag (BFS) and a multicompound activator of Na2SiO3 and NaOH solutions. The FA/BFS ratios were 100:0, 70:30, 60:40, 50:50, 40:60, 30:70 and 0:100. The workability of geopolymer concretes was performed by using slump test...conference paper 2015

Zhou, J. (author), Qian, S. (author), Sierra Beltran, M.G. (author), Ye, G. (author), Van Breugel, K. (author), Li, V.C. (author)Nowadays limestone powder and blast furnace slag (BFS) are widely used in concrete as blended materials in cement. The replacement of Portland cement by limestone powder and BFS can lower the cost and enhance the greenness of concrete, since the production of these two materials needs less energy and causes less CO2 emission than Portland cement...journal article 2009
