abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Fiber reinforced Polymers (FRP) have widely used for the purposes of enhances strength and ductility of concrete columns. Proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with FRP. In this paper, the influence of FRP thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...
An experimental work was carried out to investigate some mechanical properties of Reactive Powder Concrete (RPC) which are particularly required as input data for structural design. These properties include compressive strength, flexural strength, tensile strength and static modulus of elasticity. A combined laboratory and modeling study was undertaken to develop a database of the estimation ab...
Adapted structures must be developed so that modern reactive powder concretes (RPC) can be incorporated into new construction projects in an efficient and logical way. The steps of this development, from the analysis of the material characteristics, to the determination of the structural requirements, to the arrival at an appropriate adapted structure are described. An Outlook on the developmen...
