Corrigendum to “Evaluation of the mechanical properties and durability of cement mortars containing nanosilica and rice husk ash under chloride ion penetration” [J. Constr. Build. Mater. 78 (2015) 354–361]

Crystalline admixtures and industrial by-products can be used in cement-based materials in order to improve their mechanical properties. The research examined long-term curing and the exposure to environmental actions of polymer–cement mortars with crystalline admixture (CA) and different by-products, including Bengħisa fly ash and Globigerina limestone waste filler. The by-products were introduced as a percentage replacement of the cement. A crystallization additive was also added to the mixtures in order to monitor the improvement in durability properties. The mechanical properties of the mortar were assessed, with 20% replacement of cement with fly ash resulting in the highest compressive strength after 540 days. The performance was analyzed with respect to various properties including permeable porosity, capillary suction, rapid chloride ion penetration and chloride migration coefficient. It was noted that the addition of fly ash and crystalline admixture significantly reduced the chloride ion penetration into the structure of the polymer cement mortar, resulting in improved durability. A microstructure investigation was conducted on the samples through Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy (SEM-EDS). Crystals forming through the crystalline admixture in the porous structure of the material were clearly observed, contributing to the improved properties of the cement-based polymer mortar.

Abstract This paper presents the effect of rice husk ash (RHA) as fine filler, partially replacing sand (fine aggregate) in the composition of epoxy resin based polymer mortar (PM) and polymer concrete (PC), to make them advantageous and lessen their adverse effects on the environment. Assessment was carried out on the basis of the mechanical (compressive, flexural, tensile strength), physical (water sorption, chloride ion penetration) and morphological (porosity) properties of polymer mortar and polymer concrete. The microstructure of the PM specimens (with RHA and without RHA) is examined by scanning electron microscopy (SEM). The amount of RHA in the composition of PM and PC is optimized. The experimental result shows that the optimum replacement of sand by RHA in the composition of PM and PC has a favorable influence on mechanical, physical and morphological properties of the mortar and concrete.
