Effect of textile waste on the mechanical properties of polymer concrete

Abstract

The mechanical behavior of polymer concrete reinforced with textile trimming waste was investigated. Two series of polymer concrete formulations were studied, with different resin/sand (i.e. binder/fine aggregate) weight ratios. In each series, recycled textile chopped fibers at 1 and 2% of the total weight was used. Flexural and compressive tests were performed at room temperature and load vs. displacement curves were plotted up to failure. In the study, both the influence of fiber content and resin/sand weight ratio were considered relative to the behavior of polymer concrete reinforced with textile fibers. A decrease in properties was observed as function of textile fibers content. When specific properties were considered, this tendency was kept. However, higher textile fibers content lead to a smoother failure, unlike brittleness failure behavior of unreinforced polymer concrete.

Sustainable waste recycling solution for the glass fibre reinforced polymer composite materials industry

“…This is mainly due to the hermetic nature and superior binding capacity of resin matrices. Industrial wastes and by-products, such as fly ash, slag, wood shavings, contaminated foundry sand, marble wastes, cork powder and granules, tire rubber crumbs, textile wastes, plastic chips proceeding from milled waste electrical cables, grinded PET and PVC wastes, have been successfully used for partial replacement of filler and mineral aggregates components in PC materials e.g., [33][34][35][36][37][38]. However, little research so far addressed the (re)use of mechanically recycled GFRP wastes in concrete-polymer composites.…”

Mechanical properties of castor oil polymer mortars

“…The aggregate was foundry sand with a homogeneous grain size, with uniform grains and a mean diameter of 300 μm, with finesses modulus between 3 and 5. The specific gravity of the foundry sand was 2.63 g/cm 3 . The foundry sand was previously oven dried and then, added to the castor oil resin to reduce moisture content, insuring a good bond between the natural polymer and the inorganic aggregate.…”

“…The pre-polymer was synthesized from diphenylmethane diisocyanate (MDI) and pre-polymerized with a polyol also derived from castor oil, keeping a percentage of isocyanate free for posterior reaction. The approximate densities of the pre-polymer and polyol were 1.17 and 0.98 g/cm 3 , respectively. The castor oil resin was processed mixing the procepolyol and pre-polymer in a weight ratio of 1:1.…”

“…PM was first developed in the 1950's and then became widely known in the 1970's 1 . The composition of PM is determined by its applications, and its strength is influenced by ratio of aggregate to resin content 2,3 . PM is used very efficiently in precast components.…”

Fracture mechanics of polymer mortar made with recycled raw materials

“…Resin content was 12% by weight and no filler was added in formulations. Previous studies carried out by the author 9 , considering an extensive experimental program, allowed an optimization of mortar formulations that are now being used in the present work.…”
