Short-Term and Long-Term Behaviour of Reinforced Self-Compacting Concrete Structures
Description:
Self-Compacting Concrete (SCC) refers to a 'highly flow-able,non-segregating concrete that can be spread into place, fill the formwork,and encapsulate the reinforcement without the aid of any mechanicalconsolidation. SCC is regarded as one of the most promising developments inconcrete technology due to significant advantages over Conventional Concrete(CC). In this study cracking caused by external loads in reinforced SCC andFRSCC slabs is examined experimentally and analytically. The mechanismsassociated with the flexural cracking due to the combined effects ofconstant sustained service loads and shrinkage are observed. One of theprimary objectives of this study is to develop analytical models thataccurately predict the hardened mechanical properties of SCC and FRSCC.Subsequently, these models have been successfully applied to simulatetime-dependent cracking of SCC and FRSCC one-way slabs.

Review from Ringgold Inc., ProtoView:
Structural engineer Aslani describes the behavior of a kind of concrete that can be spread into place and will fill the formwork and encapsulate the reinforcement without the aid of any mechanical consolidation. In particular he looks at cracking caused by external loads in reinforced and fiber-reinforced self-compacting concrete due to constant sustained service loads and shrinkage. He describes analytical models he has developed to predict the hardened mechanical properties of the concretes accurately, and demonstrates how to apply them to simulate time-dependent cracking of one-way slabs.
