An abbreviated research study on use of shrinkage-compensating expansive concrete in 

 sandwich-type wall and roof panels containing insulation at mid-thickness is described. The 

 use of expansive concrete is shown to be a technically viable concept for eliminating shrinkage 

 cracking, thus preventing moisture penetration which can reduce insulation effectiveness, 

 cause deterioration of the insulating material, and accelerate steel corrosion. Embeddable
