Abstract
Cement stabilized rammed earth (CSRE) is one of the developed and affordable housing technologies, adopted in many countries, which has been used in Sri Lanka since 2004 for building single and two-floor houses. Steel slip-form and timber formwork have been used for casting walls. Information collected on wall cracks under these two methods is analyzed to justify the reasons for these cracks. Data collected at the initial stage of construction and its serviceability period of 12 years is considered under this study. Most of the walls have been in satisfactory condition, but few had to be repaired. CSRE wall tends to crack similar to other masonry technology due to faulty construction and environmental changes. Major issues are the cracks due to shrinkage of CSRE material which appeared after one year period of construction. Detailing the construction with the provision of shrinkage cracks is required to mitigate the vertical cracks on CSRE walls.
Highlights
OBJECTIVESThe main objective of this study is to investigate and analyze the wall cracks encountered on cement stabilized rammed earth walls of houses
Rammed earth is a traditional technology for building house walls used in many parts of the world
The main objective of this study is to investigate and analyze the wall cracks encountered on cement stabilized rammed earth walls of houses
Summary
The main objective of this study is to investigate and analyze the wall cracks encountered on cement stabilized rammed earth walls of houses. Recognize wall cracks on buildings masonry walls. Examine the most common cracks on CSRE walls at their initial stage of construction or their serviceability stage. Determine the causes of these cracks with respect to the theory of cracks in masonry buildings. Propose good practices for mitigating such situations
