Building as if People Mattered

House building has developed from traditional, vernacular, handmade to industrialized, mechanical and highly specialized. The natural building movement brings back to our awareness what we…

LEHM 2008

The LEHM 2008, the 5th international conference and trade fair on building with earth, will take place in Koblenz, Germany, and covers a wide variety of topics, ranging from case studies of current earth building projects, new technological developments in building with earth and the establishment of norms, information networks, training and education in earth building, and current research and problems in earth building practice around the world. The confererence closes with a choice of field trips in the earth building region around Koblenz.

TerraBrasil 2008

The Terrabrasil 2008 is the second Ibero-American congress on architecture and construction with earth and takes place in São Luís, a city with a significant historical legacy that is known for its beauty and hospitality. The Congress aims to bring together professionals, researchers, students and interested persons and is open to all independent of their specific background.

Kerpic '08: Learning from earth architecture in climate-change

Kerpic ’08 intends to bring together the related disciplines of architects and engineers, on material, construction, marketing and environmental science to create database, technology watch and strategy.

Mediterra 2009

Mediterra 2009 aims principally to assess the state of research related to earth architecture in the Mediterranean region, to study recent developments in the fields of heritage conservation and architectural design as they relate to earth architecture, and to create more active networks among professionals in the region whose work relates to earth architecture.

Moisture transfer and change in strength during the construction of rammed earth walls

A number of rammed earth projects constructed in recent years in Germany testify to the high level of architectural interest in this material in our country. Rammed earth has been “rediscovered” because of its unique materiality and fascinating and individual surface aesthetics, particularly by young architects. In connection with the realisation of two rammed earth projects realised in Thuringia in 2003/4 some questions arose concerning the processes of moisture transfer and changes in strength properties during construction. The earthen building standards document only very rough estimates of drying times for rammed earth walls. The idea arose to develop a test program for investigating the question of drying time with regard to the change in material strength in rammed earth walls, as well as for general aspects of testing procedures for rammed earth in standards. The paper presents first results of a laboratory program trying to approach to this very complex problem. A series of test specimens were produced and the unconfined compressive strength UCS were determined varying the drying times from 7 to 90 days. The moisture content of the test specimens was also varied: at OMC (PROCTOR test), lower and higher OMC.
