•A lightweight composite is obtained with the addition of waste rubber to gypsum.•There is physical compatibility between gypsum and pipe foam insulation waste rubber.•This composite can be part of the core of plasterboards used in construction.•Mechanical strength decreases with an increase in waste rubber addition.•Samples’ flexural strengths with different waste proportions fulfill EN Standards.
Industrial production of pipe foam insulation generates huge volumes of scrap material, driving to a serious environmental problem.This research studies the potential of adding different size particle proportions of this waste rubber to a plaster matrix. For this purpose, an experimental plan has been elaborated which characterizes the physical and mechanical behavior of the new composite: Shore C hardness, flexure and compressive strength. Furthermore, different particle sizes, weight rates and water/plaster ratios have been analyzed.In view of the results this waste rubber could be incorporated in gypsum based composites forming part of new lightweight products.
