This paper presents the preliminary results of an experimental research on the influence of heat and steam curing on the performances of one-part alkali-activated mortars based on low calcium fly ash (FA) and ground granulated blast furnace slag (GGBFS) with different GGBFS/FA ratios. The mortars were manufactured at equal water to precursor ratio and were activated by sodium silicate, potassium hydroxide and sodium carbonate in powder form. In general, by growing the GGBFS/FA ratio, the workability of fresh mortars decreases and the elasto-mechanical performance increases, independently of curing conditions. The heat and/or steam curing temperatures equal to 40°C or 60°C promote the development of higher early compressive strength respect to standard curing conditions (20°C), especially at high GGBFS/FA ratios, while no advantages were detected at longer ages.

Nanoscale reinforcements have strong promise in designing ecofriendly green bionanocomposites by combining (natural/bio) fibers with biodegradable polymers. However, the poor fire resistance of these organic materials restricts their applications in some industrial fields such as the textile, electric and electronics industries. Indeed, the textile industry is probably the first ones to point out the durability of flame retardancy as a major issue. In this paper, fibers of poly(lactic acid)/cellulose nanowhiskers (PLA/CNW), and poly(lactic acid)/cellulose microcrystalline (PLA/MCC) were prepared by melt spinning at filler content of 1 and 3 wt%, in the presence of 7 wt% of PLA-grafted-maleic anhydride (PLA-g-MA) used as the compatibilizer. The flame retardancy properties of the samples were investigated by Pyrolysis Combustion Flow Calorimeter (PCFC) test. The results showed that the addition of MCC and CNW to PLA fibers led to the formation of a protective char layer, which protects the bionanocomposite sample from the action of heat flux and flame during combustion. Furthermore, the incorporation of 1 wt% of CNW to PLA resulted in better flame retardancy properties than MCC due to better morphology as well as dispersion of CNW in the polymer.
