Despite being combustible, it is a stable structural element when confronted with flame due to its low thermal conductivity and characteristics of its chemical degradation (Pyrolysis). The level of fire resistance is determined by the mass, size, and configuration of the constructive elements used. When wood is used as a cladding material, takes the form of boards, plates, or other thin strips, therefore its behavior is subject to its combustibility. This risk is why building fire-safety codes and regulations in many countries have been increasingly restricting the use of combustible claddings. In this study we used modeling techniques and computer fire simulations to evaluate the influence of facade configuration on fire trajectory and the level of protection it can offer at the facade surfaces. Based on our results, it is possible to consider the use of horizontal projections, provided that they are of sufficient size (greater than 1.2m), to control the spread of fire and heat flow on the building’s facade. The study was performed using field models of computational fluid-dynamics. Particularly through the software: Fire Dynamics Simulator (FDS) to solve numerically the mathematical integration models, PyroSim for the graphical interface, and Smokeview for viewing the results 2012-10-04T10:49:46Z Prototype of façade fb720: Report on the life cycle analysis of the materials.

In this research work we evaluate ternary systems from CAC/FA/C$ mixtures, focusing on their durability. Selected formulations in the ternary system CAC/FA/C$ hydrated and carbonated have been studied at 14 and 90 days of carbonation time. The carbonation process of ettringite phases and calcium aluminate hydrates proceeded from different formulations, i.e. calcium aluminate cement, fly ash predominance, and calcium sulphate is analysed and discussed by means of infrared spectroscopy, x-ray diffraction but also mechanical properties of samples. The analysis of the results have shown that developed hydrated compounds depend on formulation; after carbonation process, the ettringite decomposition can promote metastable calcium carbonate polymorphs (aragonite and vaterite) due to inorganic compounds (aluminium hydroxide, gypsum, etc) presence. Long term carbonation of the blended samples analysis by Raman spectroscopy allows the identification of a new hydrated phase with carbonate, sulphate and calcium ions in its structure. Description: Originality This paper describes for the first time a study of the durability of different selected formulations in the ternary system CAC/FA/C$ which substitutes the Portland cement by by-products. On the hydrates characterization, the Infrared and Raman spectroscopies allow the identification of differentiate ettringite structures. 2012-02-14T09:19:55Z
