Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research was to determine whether precast prestressed bridge elements with congested reinforcement could be cast using self-consolidating concrete (SCC) without vibration and yet comply with all parameters of strength, no honeycombing, and void-free surface finish. Eight wall panels and eight BT-72 13-ft long girder sections were fabricated in two precast plants. A qualitative and quantitative evaluation of the surface finish, and homogeneity of the concrete throughout the specimens was performed. Strength, creep, shrinkage and chloride permeability of the SCC field mixes were investigated. Good quality SCC mixes were produced for the walls and the BT-72 girder sections, which completely filled the specimens without the need of internal or external vibration, and resulted in a superior surface finish and a homogenous distribution of the aggregate throughout the section.

Available in PDF, EPUB and Kindle. Book excerpt: Self-Compacting Concrete (SCC) is a relatively new building material. Nowadays, its use is progressively changing the method of concrete placement on building sites. However, the successful use of SCC requires a good understanding of the behavior of this material, which is vastly different from traditional concrete. For this purpose, a lot of research has been conducted on this area all over the world since 10 years. Intended for both practitioners and scientists, this book provides research results from the rheological behavior of fresh concrete to durability.

Book excerpt: La préfabrication des éléments de béton est un domaine dans lequel la vitesse de production et la qualité du produit sont primordiales. Les développements techniques et les méthodes de production avec lesquels la qualité du produit est améliorée tout en réduisant la quantité de main-d'oeuvre nécessaire sont alors devenus très importants pour cette industrie. De plus, dans les éléments préfabriqués, la forte présence d'armatures de renforcement, des câbles de précontrainte et des gaines de postcontrainte utilisés pour la construction de ponts créent une congestion importante au niveau des coffrages. Le béton utilisé pour ce type d'application doit être très fluide afin de pouvoir bien enrober ces renforcements, tendons et gaines de postcontrainte, et ce, sans toutefois créer de la ségrégation. Le développement des bétons autoplaçant (BAP) devient donc une alternative très intéressante pour les préfabriquants. Le BAP est un béton très maniable qui peut facilement s'écouler au travers d'éléments fortement armés ou ayant une géométrie très complexe sans qu'il y ait du ressuage ou de la ségrégation. Cependant, l'absence d'études spécifiques sur les BAP utilisés dans ce domaine nuit grandement à l'implantation de ce nouveau type de béton à hautes performances. De nouveaux essais de contrôle de la qualité ainsi que de nouvelles procédures d'essai doivent être mis au point, doivent être adoptés afin de caractériser et de contrôler les propriétés autoplaçantes de ce matériau. Le programme expérimental qui a été entrepris au cours de cette étude avait objectifs suivants: (1) Évaluer l'effet de la taille du granulat, le type de granulat, le type de liant, le rapport eau/liant sur la maniabilité ainsi que sur le développement des résistances en compression des BAP; (2) Évaluer, à l'aide de plan d'expérimentation factoriel l'impact de la variation des caractéristiques et du dosage des divers matériaux utilisés pour la fabrication des BAP; (3) Comparer la performance des divers essais de maniabilité et suggérer des critères de performances; (4) Évaluer la validité des valeurs cibles couramment employées pour les essais de contrôle de la qualité du BAP par rapport aux performances structurales obtenues sur des murs expérimentaux. À la suite de cette étude, les résultats ont démontré qu'une combinaison adéquate d'essais permet d'évaluer la stabilité dynamique des BAP en usine. De plus, une méthode simplifiée de calcul du degré de ségrégation permet d'évaluer de façon plus rapide la stabilité statique de ce type de béton. L'utilisation du plan d'expérimentation factoriel 2 5-1 a permis d'élaborer des modèles statistiques permettant de prédire les propriétés à l'état frais et les résistances en compression après 18 heures de cure à la vapeur et à 56 jours de BAP fait avec divers dosages en liant, rapport eau/liant, dosage en agent de viscosité, types de liant et ratio sable/agrégats. Finalement, à la suite d'essais d'arrachement de torons d'acier dans des murs expérimentaux de béton, il fut démontré que les murs faits avec des BAP possèdent une adhérence et une uniformité similaire, voire même supérieures, à un murs fait à l'aide d'un béton haute performance consolidé à l'aide de vibration interne.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to determine the effect and the mechanisms associated with replacing 15% of the cement by limestone filler on the mechanical properties and durability performance of self-consolidating concrete designed and cured for precast/prestressed applications. This study investigates the role of limestone filler on the hydration kinetics, mechanical properties (12 hours to 300 days), microstructural and durability performance (rapid chloride permeability, linear shrinkage, sulfate resistance, freeze-thaw resistance and salt scaling resistance) of various self-consolidating concrete mix designs containing 5% silica fume and steam cured at a maximum holding temperature of 55°C. This research also examines the resistance to delayed ettringite formation when the concrete is steam cured at 70°C and 82°C and its secondary consequences on the freeze-thaw resistance. The effect of several experimental variables related to the concrete mix design and also the curing conditions are examined, namely: limestone filler fineness, limestone filler content, cement type, steam curing duration and steam curing temperature. In general, the results reveal that self-consolidating concrete containing 15% limestone filler, steam cured at 55°C, 70°C and 82°C, exhibited similar or superior mechanical and transport properties as well as long term durability performance compared to similar concrete without limestone filler. When the concrete is steam cured at 55°C, the chemical reactivity of limestone filler has an important role in enhancing the mechanical properties at 16 hours (compared to the concrete without limestone filler) and compensating for the dilution effect at 28 days. Although, at 300 days, the expansion of all concrete mixes are below 0.05%, the corresponding freeze-thaw durability factors vary widely and are controlled by the steam curing temperature and the chemical composition of the cement. Overall, the material properties indicate that the use of 15% limestone filler as cement replacement is a viable option for the precast/prestressed concrete applications, and in addition, would also have economic and environmental benefits.
