WHY SLABS CURL. PART II: FACTORS AFFECTING THE AMOUNT OF CURLING

This paper provides an overview of some of the factors that affect curling in concrete slabs. Factors that may affect curling deflection include: amount of drying shrinkage, modulus of subgrade reaction, concrete compressive strength and modulus of elasticity, reinforcement ratio, slab thickness, joint spacing and curing. Some of these factors, such as reducing drying shrinkage, adding reinforcing bars and increasing slab thickness have been shown to have a major effect in reducing the amount of curling deflection, while other factors have little or no effect.
