Abstract. In this research, an investigation was carried out on the effect of sodium sulphate attack on the durability of composites produced with waste polyethylene terephthalate (PET). Experiments were accomplished on limestone sand and cement mortars where the blended Portland cement was partially replaced by various volume fractions of waste PET particles (6%, 12% and 17%). The test solutions used to supply the sulphate ions and cations were 5%sodium sulphate solution. Compressive strengths measured on specimens were used to assess the changes in the mechanical properties of PET-mortars exposed to sulphate attack at different ages, mainly the Young modulus of elasticity. Based on experimental compressive tests on PETMortar composite specimens and there densities, the evolution of Young modulus of elasticity has been analyzed in accordance with normative models given by (ACI-318) and (BS-8110) codes of practice. In addition, a comparative study has been carried out for corrosion resistance coefficients K of unmodified mortar to those modified with waste PET particles. It can be noticed that, for the composite immersed in a corrosive Na 2 SO 4 solution, the corrosion resistance coefficients decrease with the increase of the immersion period. The corrosion sulphate resistance K based on Young modulus before and after immersion of PET-mortar composites is better than that of the control mortar. Therefore, for safety considerations of PET-mortar composites use, ACI 318 is recommended code for design and investigation works. Also, it can be concluded that adding waste PET by volume fractions (6%, 12% and 17%) to blend Portland cement renders this cement more resistant to the sodium sulphate aggressive medium. Therefore, composites materials based waste PET are often presented as the materials of the future because of their potential for innovation and the advantages they offer. In fact, using waste PET as cement substitutes reduces the energy consumption. These modified mortars address problems related to environmental pollution by CO 2 emissions, and are used to repair various reinforced concrete structures in sodium sulphate aggressive mediums.

“…number of material properties. In the last past decades, several studies have been worldwide devoted to the development of waste materials in the composition of concretes [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] to build up composite materials which could lead to the design of innovative concretes with better performances and environmental sustainability. Particular attention was accorded to the case of concrete reinforcement with PE polymer particles.…”

“…The use of these aggregates in precast products that are widely employed in construction, such as hollow blocks and building bricks has been studied. These products have demonstrated superior properties in terms of thermal and acoustic insulation, and bending and cracking shrinkage resistance when compared to conventional units [13] [5] [14]. Moreover, using these rubberized masonry units in vertical facing walls or slabs is an excellent energy-saving strategy given that they reduce the annual energy consumption of building maintenance [15].…”

Waste tire rubber is a promising lightweight aggregate for building products that enhances their thermal and acoustic properties. Even the environmental benefits of its use are evident, higher cost and significant changes in compressive strength and workability hinder its widespread adoption. This article examines the use of crumb rubber (CR) as aggregate in dry-mix mortars to produce rubberized long hollow blocks and bricks using automated bricks machines. CR was incorporated over a range of 10-40% with water/cement ratio varying from 0.7 to 0.9. The production of rubberized bricks exhibited better performance than long hollow blocks in factory trials. Tests showed important deformations and drastic reduction in compressive strength, especially for crumb rubber percentages greater than 20%. Due to this and the high cost of CR, caution must be taken with the design of new rubberized building products to make sure they are profitable.
