Influence of thermal curing on the physical and mechanical properties of ultra-high-performance cementitious composites with glass powder
Abstract This paper discusses the impact of thermal curing and particle packing on ultra-high-performance concrete (UHPC) that used glass powder as a partial replacement of Portland cement. For this, specimens with 0% and 50% of glass powder (volumetric substitution to cement) were produced, as well as two mixtures obtained by particle packing. The samples were submitted to thermal and standard curing to compare the effects and tested for compression strength and capillary water absorption. The results show that thermal curing improves resistance expressively in the early ages while particle packing applied to the mix design improved significantly the concrete properties, indicating that glass powder is a viable substitute for cement.
