FUNDAMENTAL EXPERIMENT FOR PROPERTIES OF WALL CLAY(Materials and Construction)

Abstract

This paper presents the experimental method to estimate the physical properties of wall clay. The suitable size and flow value of test-piece, made up by mixing original wall clay with the flow value 170±10 and fibers for plastering (Susa in Japanese), are 40×40×160mm and 135±10, respectively. The standard sand-soil ratio (S/C) is 85%. Strength of wall clay proposed here takes 0.05〜0.2N/mm^2 for bending, 0.5〜2.5N/mm^2 for compressive, and 0.4〜1.3N/mm^2 for shear.
