“…The masonry of historic buildings is stabilized by the use of mortars, consisting of silica and calcite formed by the carbonation of Ca(OH) 2 [1]. The calcitic materials of the built cultural heritage deteriorate upon contact with water from wet precipitation [2,3]. Calcite is the basic component and model inorganic compound of calcitic building elements and is susceptible to the action of various physical, chemical and biological factors [4].…”

Protection of Historical Mortars through Treatment with Suspensions of Nanoparticles

Mortars, which are very important elements for the integrity of historic monuments, consist mainly of calcium carbonate and silicates in different proportions. Chemical dissolution due to exposure in open air is very important for the degradation of mortars. Inorganic nanoparticles with chemical and crystallographic affinity with mortar components are expected to be effective structure stabilizers and agents offering resistance to chemical dissolution. In the present work, we have developed and applied suspensions of amorphous calcium carbonate (ACC), silicon oxide (am-SiO2) and composite nanoparticles by the precipitation of ACC on am-SiO2 and vice versa. The application of suspensions of the synthesized nanoparticles on three different historical mortars of Roman times (1st century AD), retarded their dissolution rate in solutions undersaturated with respect to calcite, in acid pH (6.50, 25 °C). All three test historic mortars, treated with suspensions of the nanoparticles prepared, showed high resistance towards dissolution at pH 6.50. The ability of the nanoparticles’ suspension to consolidate the damaged mortar was the key factor in deciding the corresponding effectiveness in the retardation of the rate of dissolution. The combination of ACC with am-SiO2 nanoparticles showed high efficiency for protection from the dissolution of calcite rich mortars.

“…Thus, currently, there is a significant necessity to improve new and coherent policies focusing on the management, preservation and protection of the built heritage environment considering new possible scenarios of external environmental hazards such as the effects of climate change. Hence, institutions, authorities and stakeholders have accepted the inevitable requirement to maintain their socio-cultural resources [9]. This is paramount because the renovation of urban heritage city centres offers several benefits related to several variables associated with regenerating neighbourhoods [10], which could be more appropriate for possible new external investments.…”

An Approach Concerning Climate Change and Timber Building Resilience: Araucanía Region, South Chile

2021

View full text Add to dashboard Cite

This study analysed climate change effects concerning the resilience of timber buildings located in southern Chile, specifically in two cities: Collipulli and Temuco (Araucanía Region). A digital fuzzy logic method was used in a set of timber buildings declared as heritage conservation buildings by Chilean Government standards. The outcomes revealed that climate change impacts did not substantially alter the functional performance of the set of heritage timber buildings examined. This study’s results can assist in developing upcoming strategies or recommendations that can support adaptation policies for administering architectural heritage regarding climate change forecasts. These data will invaluably help stakeholders who support the conservation of timber structures located in the southern environment of Chile and under the changing climatic hazard.

Hydrographical Flow Modelling of the River Severn Using Particle Swarm Optimization

A model is presented to model hydrographical flow, which we apply to flood forecasting in the River Severn catchment area. The approach uses Particle Swarm Optimization (PSO), a swarm computation heuristic, to produce a predictive model of hydrographical flow. Hydrological flow data from 1980 to 1990 are considered, comprising the daily average flow through the River Severn and its tributaries. PSO models are developed from each year of data and are applied to predict flow in the other 10 years; model performance is shown to be largely independent of the training year, suggesting the catchment system is stable and the approach is robust. Importantly, and in contrast to most of the existing alternatives, flow is derived from data measurements taken 2 days previously, as demanded for early-warning flood prediction. The cross-validated model for prediction of extreme (Q95) events R2 = 0.96, significantly improving upon multiple linear regression R2 = 0.93, the best performing of current existing methods.
