The Korea Cement Association reports that domestic cement consumption has 47.29 million tons in 2013. The cement industry is one of the primary producers of carbon dioxide. There has been a lot of research in order to protect the global environment and to reduce the consumption of cement. This experimental study is purposed to analyze the effect of red mud and alkali activator on engineering properties of non portland cement matrix using blast furnace slag. Various specimens were prepared with non portland cement matrix and the addition ratios of red mud and alkali activators. The physical properties of these specimens were then investigated by flow test, setting time test, compressive strength test, flexural strength test, EDS and observation of SEM. Results showed that is the most suitable alkali activator for non portland cement matrix using red mud and blast furnace slag. It was judged that results of engineering properties on the alkali activated inorganic binder with kind of alkali activators and red mud were useful to basic data for mixtures design and evaluation properties of non portland cement matrix.
