Abstract
This paper aims to evaluate the impact of thermal curing and the use of particle packing in ultra-high-performance concrete (UHPC) using glass powder as a partial substitution of Portland cement. For this, specimens with 0% and 50% of glass powder (volumetric substitution to cement) were produced, as well as two mixes obtained by particle packing. The samples were submitted to thermal and standard curing to compare the effects. The samples were tested for compression resistance and capillary water absorption. The results indicate that thermal curing provides a high gain of resistance in early ages, the application of particle packing in the mix design resulted in a significant improvement in the concrete properties and the glass powder presented as a viable substitute for cement.
