SP38-03

Date: 

January 1, 1973

Author(s):

P.K. Mehta

Publication:

Symposium Papers

Volume:

38

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.

Abstract:

SP38 A comprehensive study of the use of expansive cements and their effects on cracking in concrete. Covers research, design, field applications, and self-stressing. Contains 20 papers, including reports on use of expansive cement in walls, reinforced concrete pipe, pavements, grout, taxiways, and slabs.

Publication:

Symposium Papers

Volume:

38

Abstract:

The use of expansive cement in continuously reinforced and prestressed concrete pavements could be effective not only in comprensating drying shrinkage of concrete pavements but also in inducing a self-stress due to the restraint of expansion by subgrade friction and reinforcement, if the expansion of ocncrete due to expansive cement existed sufficiently for a long period. Therefore the application of expansive cement to concrete pavements were examined experimentally in the laboratory and field work.
