Physical and Mechanical Properties of Cement Pastes with Blended Binder Containing Fine Milled Glass
Abstract:
Physical and mechanical behaviour of cement pastes with partial Portland cement replacement by fine milled waste glass is researched in the presented paper. The tested pastes contain milled borosilicate glass in amount of 5, 10, 20, and 30 mass% of cement. The chemical composition of borosilicate glass and used Portland cement is accessed by XRF (X-Ray Fluorescence) analysis. For the milled glass, pozzolanic activity and particle size distribution are measured. Here, modified Chapelle test is used for evaluation of pozzolanic activity. Particle size distribution is measured on laser diffraction principle. Basic physical properties and mechanical properties are determined for samples cured 28 and 90 days in water in order to evaluate the kinetics of hydration process. The obtained results revealed the possible applicability of the tested borosilicate glass in the composition of cement-based composite materials.
