IMPROVED ADOBE MUDBRICK IN APPLICATION – CHILD-CARE CENTRE CONSTRUCTION IN EL SALVADOR

摘要

Major earthquakes in Latin America, Asia and The Middle East have served as recent reminders of the vulnerability of traditional adobe (mudbrick) dwellings to the force of earthquakes. A host of research, training and construction projects continue to address this precarious situation and there have been various publications describing the developments in improved adobe (mudbrick) design and construction in recent years. These publications have mostly originated from research institutions and have tended to focus on the technical and experimental details of a variety of improvement systems. The dissemination of this important information is a vital component in the challenge to promote and build safer homes. Furthermore, these advances in technical detail must be accompanied by practical information, which relates to the actual application of the proposed systems, addressing the advantages and disadvantages of each technique. This paper attempts to address the current deficiency of this practical information, and thus provide adobe constructors and proponents with a realistic understanding of some of the practical issues related to improved adobe construction. This paper describes the technical and practical aspects and 'lessons learned' from a recent improved adobe construction project in El Salvador, as well as drawing on field investigations, laboratory research and other literature. The paper concludes with a proposed addition to the current technical evaluation of the performance of improvement systems: the assessment of the skill level and resources required to effectively incorporate improved adobe systems. This additional information will be of particular interest and value to supporters of improved adobe projects, such that training and construction activities may be tailored to meet the skill and resource capacities of the organization and beneficiary groups involved.
