dc.description.abstractAlkali activation is a promising method of reducing cement production considerably without further significant investments. Utilizationof these materials are of extreme importance when environmental aspects such as CO2 emissions and energy consumptions areconsidered. In this article, effect of activator modulus and alkali content on fresh behavior and mechanical properties were investigated.12 M NaOH solution and sodium silicate solution with a modulus of 3 were used. Water-to-binder ratio was selected as 0.5 for allspecimens where binder content was calculated as the total of slag content plus activator solids. Slag content was 500 kg/m3 for allmixtures. Mechanical tests were conducted on 40 x 40 x 160 mm prismatic specimens. Results indicate that mechanical propertiesof alkali activated mixtures are highly dependent on both parameters hence proper optimization of these two parameters becomescompulsory. In this study, it is concluded that alkali content (Na2O/slag) should be selected 9% and whereas activator modulus shouldbe leveled near a value of 1.5. Flexural properties were also highly affected from optimization of these parameters and similar findingsare deduced. Early strength evaluations are highly dependent on activator modulus. Workability of the mixture was also assessed andit should be noted that flowability of mixture was adversely affected with the increasing activator solids content.en_US
