Influence of Plasticizing Additives on the Porous Structure and Physical and Mechanical Properties of Slag-Alkali Non-Autoclaved Foam Concrete
Abstract: The influence of MasterGlenium 115 superplasticizers by BASF and Hemix Art-2 by Russian production on the porous structure, technological and physical-mechanical properties of non-autoclaved slag-alkali foam concrete based on Donbass man-made waste was studied. Both additives allow increasing the fluidity of the porous mixture on the slag-alkali binder, but it is not possible to achieve the minimum values of the flow diameter for D600 foam concrete manufactured using the casting technology. It was found that the MasterGlenium 115 superplasticizer has a stronger retarding effect on the set of structural strength of foam concrete green mass than the Hemix Art-2 additive. However, at the design age, a greater increase in compressive strength is observed precisely in compositions with an additive based on MasterGlenium 115 polycarboxylate esters. As a result of the research, non-autoclaved slag-alkali foam concrete with a uniform porous structure of the average density grade D600 and compressive strength class B1,5 was obtained.
Keywords: non-autoclaved foam concrete, slag-alkali binder, hydraulic ash removal, superplasticizer.
