Operational energy of opaque ventilated façades in Brazil

Autores:  Ana Carolina Fernandes Maciel et Al Energy efficient buildings require envelopes designed to fit the local and the climate zone while the greatest benefit of opaque ventilated façades is the ability to reduce cooling thermal loads. The natural convection in the air chambers and the protection against solar incidence provided by the external layer reduces the energy consumed by the artificial systems used for environmental conditioning (HVAC systems). […]

Sinter-crystallization of spodumene LAS glass-ceramic tiles processed by single-firing

Autores:  Fernando Cardoso Figueira et Al For the manufacturing of glass-ceramic products, a monolithic glass is prepared using the same technologies for the conventional glass production, followed by a thermal-treatment of nucleation and crystal growth. An alternative process could be the production of glass-ceramic materials by pressing of glass powders and densification by sintering. In this way, the same equipment used in a traditional ceramic […]

α-Cristobalite formation in ceramic tile and sewage pipe bodies derived from Westerwald ball clay and its effect on elastic-properties

Autores:  Aydın Aras et Al The formation of α-cristobalite and its effect on the elastic modulus (E modulus) was investigated in sewage pipe (SP) and tile bodies derived from Westerwald ball clay (WBC), employing the results of previous research on WBC as a baseline. In this study, the SP and tile bodies derived from WBC are compared with the bodies derived from two residual Turkish […]

Self-cleaning coatings based on fly ash and bismuth-photocatalysts: Bi2O3, Bi2O2CO3, BiOI, BiVO4, BiPO4

Autores:  E. Luévano-Hipólito et Al Recently, the design of photocatalytic building materials for self-cleaning, self-disinfecting, and environmental pollution remediation has resulted in increasing interest. The advantage of using solar energy and rainwater as driving force has opened a new domain for environmentally friendly building materials. This work reports the fabrication of photocatalytic self-cleaning coatings with alternative building materials such as fly ash, sodium carbonate as an […]

Assessment of construction cost reduction of nearly zero energy dwellings in a life cycle perspective

Autores:  Michele Zinzi et Al Concerning Nearly Zero Energy Buildings, it is important to guarantee energy efficiency, thermal comfort and indoor environmental quality, while keeping construction and operational costs low. In this framework, this paper explores the efficacy of applying different scenarios, for reducing construction costs of new nearly zero energy multi-family houses in a life cycle perspective. Conversely to the standard cost-optimal approach, a […]

abrication of sustainable ceramic board using solid-wastes for construction purpose

Autores: S. K. S. Hossain et Al This work aims to evaluate the feasibility of using seashell and fly ash as ingredients for fabrication of the sustainable ceramic board. The multi-phase ceramic powder (MCP) formulation was done through the mixing of 1:1 weight ratio of fly ash and heat-treated seashell as ingredients and calcined at 1100 °C. Larnite (Ca2SiO4) was a major phase, and minor phases […]

Development of unfired earthen building materials using muscovite rich soils and alkali activators

Autores: Emeso Beckley Ojo et Al Most studies have focused on the alkali activation of thermally activated kaolinitic clays for the production of innovative building materials. Whilst the widespread use of these minerals may be hindered due to geographical availability; a combination of thermal activation and alkali activator solutions yields a material with high embodied energy with implications on eco-friendliness. This study presents an eco-friendly […]

A review on cutting of industrial ceramic materials

Autores: Rahul Rakshit et Al Ceramics have garnered huge engineering applications in various manufacturing industries. This is due to their excellent mechanical properties at high temperature, good oxidation stability and high hardness. However, their inherent brittleness properties have led to difficulty in giving proper shape through machining (achieving dimensional accuracy and precision) which limit their applications. In the present study, an elaborate literature review on […]
