EFFECT OF MIX PROPORTION ON STRENGTH AND WORKABILITY OF WALL CLAY

Abstract

The demand of wall cray decreased owing to Great Hanshin-Awaji Earthquake or synthetic building material. Therefore, manufacturing plants of wall clay gave up their business in Kagawa. The previous study revealed that the strength of wall clay extracted in Kagawa is higher than other regions. The objective of this study is to examine experimentally the effect of the mix proportion on the strength and workability of wall cray and to rebuild the manufacturing system of wall clay in Kagawa. From the results of various tests, the strength of wall clay is lower, the workability is higher and the cracking area is smaller.
