主 题：Straw bale air tightness edge flat plaster material crack grading systemair
摘 要：Straw bale construction offers a renewable,sustainable and proven alternative to mainstream building methods;still,little is known about its airflow *** this end,the intent of this paper is to evaluate airtightness of fully constructed and plastered straw bale walls as well as individual plain straw *** first experiment entailed measuring the influence of straw bale orientation on airflow characteristics with the finding that straw bale considered alone has poor air flow-retarding characteristics and that plaster is the primary air barrier.A second experiment involved thirty plastered straw bale specimens using three different plaster *** this experiment,a crack grading system was developed and is herein proposed as a tool to evaluate plaster performance as an air barrier.A third experiment validated the crack grade system through application on four fully constructed straw bale *** use of the crack grading system was demonstrated on a case study straw bale house in Radomlje,Slovenia,where the predicted air tightness results were validated through comparison to results of blower door tests.
