Concrete modified with polystyrene particles is a new type of energy-conserving construction material that can be used as wall material characterized by light weight, heat preservation and insulation, and energy saving. Taking polystyrene-modified concrete as the research object, five prismatic specimens and cube specimens with different densities were prepared. The experiments were conducted to study the effect of specific gravity on the failure mode, mechanical properties and stress-strain curve of polystyrene-modified concrete. The experimen...
