Title: Studies on Slump Loss in Expansive Cement Concretes
Author(s): P.K. Mehta
Publication: Special Publication

Abstract:Slump loss or premature stiffening of cement concrete is generally caused by rapid precipitation of cement hydration products. As compared with portland cements, the expansive cements usually cause greater slump loss due to formation of larger volume of hydration products, such as ettringite and gypsum, during early stages of the hydration process.
