Numerous studies have investigated the use of waste discount greenery glass as a partial substitution in Portland cement.Nonetheless, it seems there is no consensus about the influence of particle size and color on the behavior of the compounds.This work investigates the influence of soda-lime glass microparticles on the properties of cement and mortar in both fresh and hardened states.

The effects of partial substitution (10 and 20%) of the cement by colorless and amber glass particles with dimensions of approximately 9.5 mm were investigated.The results revealed that the substitutions did not significantly affect the setting times, nor the mechanical properties of mortar at longer curing times.

The influence of glass content read more and chemical composition on workability and hydration heat was also observed.The waste glass samples showed lower thermal diffusivity than the control sample.Thermal emissivity was not influenced by the presence of glass microparticles.
