摘要

近几十年来,大多数建筑活动都发生在中东和北非地区等发展中国家。基础设施的扩张对该地区的技术、社会、经济和环境转型产生了巨大影响。建筑业对国内生产总值(GDP)的贡献在整个地区各不相同,在2-10%之间。目前,可持续建筑需要综合全面的可持续设计,包括仔细选择材料和方法。当地可用且生产和运输所需能源较少的材料将为更可持续的做法铺平道路。该地区许多国家已经意识到使用当地建筑材料对经济、社会和环境的好处。本文概述了在该地区使用可持续和负担得起的当地建筑材料以应对全球气候变化危机并促进更可持续和更环保的做法的主要趋势和机会。将审查目前使用各种建筑材料的做法,如生物基材料、处理过的城市固体废物焚烧底灰(MSWI-BA)、建筑和拆除废物、含石膏的副产品(磷石膏、脱硫石膏、硼石膏等)和夯实土。结论是,在建筑活动中使用这些当地建筑材料将促进社会的发展。然而,其中一些材料已经开发并进入实施阶段,而大多数材料仍处于研发阶段。因此,迫切需要制定全面的地方和区域战略,以提高这些材料的利用率。

Trends and opportunities of using local sustainable building materials in the Middle East and North Africa region
In recent decades, most of construction activities have been taking place in developing countries such as the Middle East and North Africa region. The expansion in infrastructure has great impact in the technological, social, economic and environmental transformation of this region. Construction sector contribution to Gross Domestic Product (GDP) varies throughout the region and ranges between 2-10%. Currently, sustainable construction requires integrated and comprehensive sustainable design including careful choice of materials and methods. Materials that are locally available and require less energy to produce and transport would pave the way to more sustainable practices. Many countries in the region have realised the benefits of using local building materials on the economy, society and environment. This paper outlines the key trends and opportunities of using sustainable and affordable local building materials in the region to respond to the global climate change crisis and to promote more sustainable and environmentally friendly practices. The current practice of using various building materials such as bio-based materials, treated municipal solid waste incineration bottom ash (MSWI-BA), construction and demolition waste, gypsum-containing by-products (phosphorgypsum, FGD gypsum, borogypsum and others) and rammed earth will be reviewed. It is concluded that the use of these local building materials in construction activities would foster the development of the society. However, some of these materials are already developed and reached the implementation stage while most of them are still at R&D stage. Therefore, there is an urgent need for a comprehensive local and regional strategies to enhance the utilization of these materials.
