IMPRESSION EVALUATION OF WORKABILITY OF PLASTERING MATERIALS EVALUATED BY PLASTERERS

Evaluation method of workability for plastering materials (Part3)

Abstract

This paper presents the impression of the workability of plastering materials evaluated by the skilled plasterers. The sensory test using the cement mortars based on various mixture proportions was carried out in order to obtain fundamental information. The fourteen evaluation items such as viscosity, softness, and tired feeling which might be related to the workability of plastering materials were prepared for the sensory test.
As a result, it was found that the plasterers could react to the differences of mixture proportions sensitively, moreover the ease of troweling and finishability are strongly related to the workability of the plastering materials.
