1. Estudo comparativo entre o concreto autoadensável e o concreto convencional vibrado em obra vertical
Resumo O uso do concreto autoadensável (CAA) tem aumentado gradualmente no Brasil, embora seu uso seja mais restrito em obras verticais. Vantagens do CAA são apontadas na literatura, tais como a diminuição do tempo de concretagem e do número de trabalhadores, contudo poucos dados numéricos comparativos com o concreto convencional vibrado (CCV) estão d

2. Study of the compressive and tensile strenghts of self-compacting concrete with sugarcane bagasse ash
Resumo Neste trabalho foram avaliadas as resistências à compressão axial aos 3, 7 e 28 dias de idade e a resistência à tração aos 28 dias de idade, de corpos de prova de duas composições de concreto autoadensável (CAA). A diferença entre ambas, era a presença da cinza do bagaço da cana-de-açúcar (CBC), na taxa de substituição de 10% da massa

3. A study of packing parameters that influence the fresh properties of self-compacting concrete
Resumo Alguns métodos de dosagem de concreto autoadensável (CAA) conhecidos são baseados no menor índice de vazios como uma proposta de empacotamento ideal. Contudo, uma composição com um menor teor de vazios não é garantia de uma boa sinergia entre os grãos maiores e menores no estado fresco. O objetivo deste estudo foi identificar e avaliar difere

4. Avaliação do grau de orientação de fibras de aço induzida na moldagem de elementos planos com concreto autoadensável
RESUMO O uso de concreto autoadensável (CAA) aliado ao concreto reforçado com fibras (CRF) tem sido objeto de várias pesquisas recentes. A combinação da fluidez do CAA com o uso de fibras aumenta a probabilidade de que, no processo de lançamento, seja possível causar orientação preferencial nas fibras, inclusive em elementos planos. Isto pode ser be

5. Behavior of the self-compacting mortar with sugarcane bagasse ash in the fresh and hardened state
Resumo O concreto autoadensável (CAA) é um material que apresenta alta trabalhabilidade e moderada viscosidade quando comparado ao concreto convencional. Em função de suas vantagens, nas últimas décadas, o CAA vem sendo investigado e as pesquisas abordam a utilização de novos componentes em sua estrutura e a busca pela melhoria de seu desempenho, tan

6. Experimental Investigation on Self-Compacting Self-Curing Concrete Incorporated with the Light Weight Aggregates
ABSTRACT Self-Compacting Concrete (SCC) flows around obstructions by its self-weight to fill entirely and self-consolidate (without any need for vibration), without any part of disconnection and chunking. The eradication of the need for consolidation leads to better quality concrete and substantial improvement of running conditions. The fresh state of SCC mi

7. Technical viability of self-compacting concretes with by-products from crushed coarse aggregate production
Abstract The main objective of this work is to present the technical viability of Self Compacting Concretes (SCC) containing by-products from crushed coarse aggregate production. For this purpose, a vast characterization of these by-products was made; six mixtures of SCC were produced using two different aggregates: granite and mica schist. The binder/dry ag

8. Bolted Shear Connectors Performance in Self-Compacting Concrete Integrated with Cold-Formed Steel Section
Abstract In conventional composite construction involving hot-rolled steel section, the composite action is usually achieved by using conventional headed shear studs connectors. However, use of headed studs is not practical for cold-formed steel (CFS) section due to its very thin form that is difficult to weld. A suitable bolt and nut type shear connector wa

9. Durability Enhancement Of SCC With Waste Glass Powder
Self compacting concrete (SCC) requires a large quantity of fine materials compared to common concrete. In this work waste glass powder was used to replace (50%) of filler required. Two types of SCC were manufactured, a control SCC type (CTL) using cement and limestone filler and another with glass powder replacing 50% of the filler. Mechanical and durabilit

10. Fresh-state Properties of Self-compacting Mortar and Concrete with Combined Use of Limestone Filler and Fly Ash
AbstractThis paper presents the results of a study on the behaviour of self-compacting concrete (SCC) in the fresh and hardened states, produced with binary and ternary mixes of fly ash (FA) and limestone filler (LF), using the method proposed by Nepomuceno. His method determines the SCC composition parameters in the mortar phase (self-compacting mortar - SC

12. Prediction of combined effects of fibers and nanosilica on the mechanical properties of self-compacting concrete using artificial neural network
In this research, the combined effect of nano-silica particles and three fiber types (steel, polypropylene and glass) on the mechanical properties (compressive, tensile and flexural strength) of reinforced self-compacting concrete(SCC) is evaluated. For this purpose, 70 mixtures in A, B, C, D, E, F and G series representing 0, 1, 2, 3, 4, 5 and 6 percent of
