Abstract
The object of study is a cement composite material with powdered utilized optical discs. The objective is to establish the dependences of the main strength characteristics - compressive strength, bending strength, and density - on the amount of waste added into the mixture and the water-cement ratio. The compositions of the mixtures for the production of the cement composite material samples consisted of the following components: cement, sand, powdered waste in the form of utilized optical discs and water. Based on the results of testing the samples, mathematical models have been developed which describe the dependences of the physical and mechanical properties of the cement composite material samples on the fraction of waste and water-cement ratio. It was found that with an increase in the amount of powdered waste added into the mixture, it reduces the compressive strength, bending strength, and density of the samples under study, however, the optimization of the water-cement ratio makes it possible to obtain equal strength compositions with a different fraction of waste. Component compositions of cement composite material mixtures with the addition of powdered utilized optical discs in the amount of 10 to 25 % of the total filler mass, which can provide construction products with a compressive strength class B20, are presented.
