Properties of wall crays in main districts: Wall clays for clay wall on bamboo lathing Part 1

The final objective of this study is to enhance the performance of clay wall on bamboo lathing and to improve its productivity in order to utilize this wall construction system widely for wooden detached houses. In this paper, various tests and analyses were carried out to investigate the properties and mix proportion of wall clays which had been used normally in some main districts. Test samples were prepared by well-skilled plasterers. The followings are concluded from the test results. Some of the soil tests and analyses are adaptable as the quality tests of wall clay. The grain size distribution is one of the most important characteristic having correlation with the consistency, drying shrinkage and compressive strength. The theory of laying undercoat with intermediate coat are different depending on the districts.
