Abstract

This article expands upon the results of previous research into inerting fly ash from urban solid waste and its encapsulation in mortar matrices. Given the heterogeneous composition of the MSWIFA, it was decided to replicate the inerting process with NaHCO3 in order to prove its efficiency. The results are conclusive, reducing the chloride content by close to 99%. Mortars were produced using two different types of cement (CEM-I and CSA) and incorporating treated fly ash using a substitution percentage of 10% in weight of the aggregate used. The physical and mechanical properties have been obtained through workability, dimensional stability, density and mechanical strength tests. The conclusions drawn are that CSA mortars containing inerted fly ash and coarser aggregates (0/4) improve the reference compressive strengths by more than 11% while bending resistance remains unaltered. These types of mortar also have a reduced workability period and better dimensional stability than the reference mortars and those containing fine aggregates (0/2).
