Self-Compacting High-Performance Concrete
TL;DR: In this article, a self-compact concrete is defined as follows at the three stages of concrete: (1) Fresh: selfcompactable; (2) Early age: avoidance of initial defects; (3) After hardening: protection against external factors.
Abstract: 1. Characteristics Self-compacting high-performance concrete is a high performance concrete that can be compacted into every corner of a formwork, purely by means of its own weight and without the need for vibrating compaction (Fig. 1). This concrete is defined as follows at the three stages of concrete: (1) Fresh: selfcompactable; (2) Early age: avoidance of initial defects; (3) After hardening: protection against external factors.

TL;DR: In this paper, a new mix design method for self-compacting concrete (SCC) is proposed, where the amount of aggregates required is determined, and the paste of binders is then filled into the voids of aggregate to ensure that the concrete thus obtained has flowability, selfcompacting ability and other desired SCC properties.

TL;DR: In this paper, the authors describe the means through which innovations are implemented, and the strategies it can employ to increase the effectiveness of these operations to capture these competitive and other expected benefits.
Abstract: Construction innovations can provide the critical component for a company's long-term competitive strategy. To capture these competitive and other expected benefits, however, a construction company needs to understand the means through which innovations are implemented, and the strategies it can employ to increase the effectiveness of these operations. Construction-related companies can follow different strategies, based upon the nature of the innovation, their capabilities, resources and overall market strategy. The six stages of implementation are generally described, followed by a description of the types of activity required for each type of innovation, with detailed case studies. L'innovation dans la construction peut etre l'atout majeur de la strategie concurentielle a long terme d'une entreprise. Pour saisir ces avantages concurentiels et d'autres avantages attendus, une societe du secteur de la construction doit cependant comprendre les moyens qui permettent de mettre en oeuvre l'innovation ainsi ...

TL;DR: In this paper, the influence of fly ash (FA) on the properties of self-compacting concrete (SCC) is investigated and the results indicate that high volume FA can be used in SCC to produce high strength and low shrinkage.
