Abstract |
This paper reports test results to assess the influence of superplasticizers and different admixture on the flow and compressive strength development of cementless mortar using developed hwangtoh binder. Test specimens were classified into four groups: series for I the mixing ratio of superplasticizers, series Ⅱ for a kind and replacement level of admixtures according to the variation of water/hwangtoh binder ratio, series Ⅲ for the specific surface area and replacement level of ground granulated blast-furnace slag, and series Ⅳ for the replacement level of powered superplasticizer agent developed to improve slump loss of concrete. The proper replacement level of each admixture is proposed for enhancement the flow and compressive strength of the hwangtoh binder mortar.
