Abstract

In-plane volume change of cement siding due to surrounding relative humidity change is discussed in this paper. The adsorption isotherm and strain isotherm under 25 degree Centigrade are experimentally obtained. From these experiments, it was found that relationships between statistical thickness of adsorption and relative humidity are very close among these sidings. And based on this characteristic, simple experimental equation to predict the statistical thickness of adsorption by relative humidity is proposed. Additionally, the value of shrinkage strain divided by water content has strong relation with statistical thickness of adsorption regardless of type of cement sidings. Based on these two points, in-plane shrinkage predictive equation is proposed.
