Sustainable Materials for Architectural Restoration in Developing Countries: from the New Historic Mixes for the Future

In this study, considerations for design and valorization of sustainable restorative materials for applications in the developing countries are investigated. The paper deals with several preliminary requisites leading to mortar design for conservation of built environment of these countries with numerous cultural heritage elements in need of conservation. Different forms of compatibility are discussed that does not exclude conceptual, physical, chemical, and aesthetical considerations. Where practicable, reversibility is a demanding property expected from such a restorative material. Moreover, sustainability of the restorative materials project is highly dependent on the environmental considerations. The suggested policies leads to significant reduction in use of materials with high carbon dioxide production and landfills. Economic considerations will also play an important role in the frame of conservation plan as their development potentially broadens the domain of conservation possibilities. This is an important value for developing countries with loads of historic buildings in need of restoration. The designation of waste-based strategy in design of restoration materials and their answer to requisites of the conservation plan are discussed. The conceptual suitability of low impact and waste-based restorative materials for treating the built environment in developing countries is justified and discussed. However, the sensetiveness of these countries in application of economic materials for restoration should be dealt with. An economic, high performance, and compatible restoration respects the feature of historic elements and is in-line with many historic material design strategies.
