Abstract

The use of waste from both industrial and agricultural sources or from the construction sector itself as alternative materials to partially or totally replace the aggregates or agglomerates of concrete/mortar has been an interesting option for obtaining eco-efficient cement compounds. The most commonly used wastes are blast furnace slag, silica fume, fly ash and waste from construction and demolition activities. Other interesting options are related to the use of sugarcane bagasse ash and glass waste. Despite the importance of cementitious compounds, there are few reports on their thermal performance, once the thermal comfort of the built environment is closely associated with the capacity of building materials to absorb, store and transmit heat to their interior. Published works indicate that replacing part of the cement with microparticles of soda-lime glass microparticles can contribute to the production of mortars and concretes of similar mechanical performance and workability, and the production of concretes durable in regard to the inhibition of the alkali–aggregate reaction. Accordingly, this study evaluated the thermal performance of mortars made with partial replacements of cement (10% and 20%) per colorless soda-lime glass microparticles and amber, and analyzed the results in relation to the surface temperature of materials after natural exposure to sunlight.
