This paper describes the use of CRT glass waste for the production of polymer concrete. The CRT glass was subjected to a multistage mechanical disintegration process, in a way that allowed obtaining grains smaller than 2 mm. A set of hybrid reinforced polymer concrete was produced by using: ground CRT glass, sand and cut glass fibers 4.5 mm and 12 mm long. The influence of the volume of fibers and the length of glass fibers on the properties of polymer concrete with 30% by volume of epoxy resin, acting as a binder was described. Tests of CRT glass were carried out, among others study of chemical composition, particle size distribution and analysis of grain morphology. For polymer concrete, the flexural strength and compressive strength were determined, and the open porosity, apparent density, and water absorption were examined. The test results showed that polymer concrete with the use of milled CRT glass is a good way to manage this problematic waste. The polymer concrete has several times better than traditional concretes and significantly lower porosity and water absorption, which makes this material advantageous in applications such as the production of thin-walled products and products exposed to water and chemical attack. The addition of chopped glass fibers leads to an increase in mechanical properties and also protects the material against rapid disintegration after exceeding the maximum tresses, which is extremely important for the safety of use of the structure in the event of a failure.

“…For many years, research has been conducted on a large scale to manage waste, including post-production waste for the production of cement matrix materials. There are several known studies into using alternative aggregate originating from waste red, sanitary and decorative ceramics [1][2][3][4][5][6][7], bottle glass, car glass and cathode ray tubes etc. In these studies, the concrete cement matrices where the authors introduced waste glass were characterized by better mechanical and physical parameters, and significantly higher sulfate resistance [8][9][10][11][12][13].…”

Most researchers focus on using waste glass as a partial replacement for fine aggregate in the cement matrix. This article proposes an alternative method of managing waste glass in the concrete industry, as an addition to concrete in the form of finely ground glass powder and as a component of the cement. Waste glass ground into a glass powder was dosed into concrete in quantities of 5 and 10% of the weight of cement while reducing the same amount of fine aggregate. Tests that were carried out on three concretes (including a control concrete) included compressive strength, water penetration depth and water absorption. Pre-shredded waste glass from white bottles was also ground together with previously burned Portland clinker. The glass was dosed in quantities of 6 and 12% of the weight of clinker. In this way, two types of cement were obtained: cement with the addition of waste glass and the control cement. Tests carried out included compressive strength after 2, 7, 14, 28 and 90 days, the beginning of cement setting time and its grinding degree. An analysis of the obtained test results confirmed the possibility of using waste glass in a way other than previously proposed. Concretes including fragmented glass from bottles have obtained satisfactory results of compressive strength, water absorption and penetration. Cements obtained as a ground mixture with waste glass were characterized by much better mechanical parameters compared to the control sample cement.
