The influence of expanded polystyrene on properties of cement-based materials
Original language description
Concrete is a versatile composite material which due to its beneficial properties e.g., form ability, fast construction process, relatively high compressive strength available in short term, considerable long-term durability, etc. may find usage in many applications throughout different sectors. Dense composite matrix which is, on the one hand, responsible for good mechanical resistance can be, on the other hand, counterproductive in view of excessive dead loading of bearing structures and its high thermal conductivity. In this paper waste expanded polystyrene as a replacement of traditional dense aggregate in concrete production was used. Polymer-based alternative, in the fraction of 2.0/4.0 mm, was applied in amounts of 0-100 vol.%, and its effect on physical, strength and thermal-physical properties on 28 days aged concretes was monitored. Obtained data confirmed combined substantial lightening of produced composites accompanied with improvement of their thermal-insulation function. High dosages of lightweight aggregate in concrete mixes led to significant reduction of their mechanical resistance, however, at balanced portions of polymeric material structural grade concrete may be manufactured.
