1. Plastic Shrinkage Cracking in Concrete
Abstract : Early-age (up to 24 hours after casting) cracking may become problematic in any concrete structure. It can damage the aesthetics of the concrete member and decrease the durability and serviceability by facilitating the ingress of harmful material. READ MORE

2. Plastic Shrinkage Cracking In Concrete : Mitigation and Modelling
Abstract : Early-age (up to 24 hours after casting) cracking may become problematic in any concrete structure. It can have a negative influence on the aesthetics of the concrete structure, as well as decreasing the durability and serviceability by facilitating the ingress of harmful materials into the concrete bulk.

3. A Study on the Mechanism of Plastic Shrinkage of Cement-Based Materials
Abstract : The work presented in this thesis has been concentrated on describing the mechanism of plastic shrinkage and on developing a method of calculating the progress of plastic shrinkage. The origin of plastic shrinkage and plastic shrinkage induced cracks has been investigated by many researchers during the last four decades, but no generally accepted theory could be found in the literature.

4. Early age properties of self-compacting concrete - Effects of fine aggregate and limestone filler
Abstract : Self-compacting concrete (SCC) is a sensitive mix, strongly dependent on the composition and the characteristics of its constituents. It has to possess the incompatible properties of high flowability together with high segregation resistance, a balance made possible by the dispersing effect of water-reducing admixture combined with cohesiveness produced by a high concentration of fine particles.

5. Structural integrity of prestressed nuclear reactor containments
Abstract : A nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. READ MORE
