Durability-related properties of early-age and long-term resistant laboratory elaborated polymer-based repair mortars

Highlights Suitability of pre-packed and laboratory elaborated PE-based mortars was evaluated. Comprehensive analyses and laboratory durability tests of cured mortars were assessed. Conventional ready-mixed and PE-based mortars exhibited similarities in performance. 10% PE-mortars were less susceptible to acids attacks and to corrosion under chlorides. Mortars with 10% (PE) and sand grains size less than 1 mm would improve performance.
Abstract This paper describes an experimental work on laboratory elaborated polymer-based mortars. A commercial ready-mixed mortar as well as laboratory elaborated normal mortar and polymer-based mortars, replacing sand with 5, 10 and 15% mass fraction of very fine polyethylene (PE) polymer particles were characterised. Acid solutions, accelerated carbonation and corrosion effects on all the mortars with a constant water-to-cement ratio were investigated. Experimental results exhibited similarities in performance between the ready-mixed fibre-based and laboratory elaborated composite mortars. In particular, polymer-based mortars with 10% (PE) demonstrated much less susceptibility to acid attack and to corrosion when exposed to chlorides. A 10% plastic waste (PE) with grain sizes of (PE) and sand not exceeding 1 mm would reduce the porosity rate and enhance the resistance to carbonation and chlorides of the polymer-based mortar as well as improve corrosion reduction effects of the reinforcements.
