Abstract:

Blends of a self-stressing expansive cement and a low-heat type II cement were used in a study of the effects of expansive cement content, water content, fine aggregate additions, and fly ash replacements on the physical properties of pumpable mortars.

Abstract:

Some degree of prestress can be achieved through the use of expansive cements. Depending on the magnitude of prestress developed, expansive cement concretes are classified as shrinkage-comprensating or as self-stressing.

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.

Symposium Papers

Volume:

38

Abstract:

The use of self-stressing types of concretes is limited to applications requiring only a low level of prestress. Each application of a self-stressing type of concrete to fabrication of structural elements or building units requires a careful investigation, not only of the properties of the concrete but also of the structural behaviors of the precast units. To date, this self-stressing type of concrete has been used in only a few structural applications.
