Abstract
The article presents the results of experimental studies to determine the effect of superplasticizer SDj-3 based on ester polycarboxylate on the porous structure of foam concrete obtained from local industrial waste using lime waste as a secondary resource. It is established that the plasticizer has a significant effect on the porous structure of calcareous foam concrete. It is noted that the additive SDj-3 makes it possible to increase the proportion of closed pores of foam concrete while reducing the volume of open pores and, instead of open capillaries, create a group of evenly distributed small spherical pores, thickening the interporous walls.
