Concrete Docility

The docility of the concrete is the ease with which a mixture of aggregates, cement and water are transformed into concrete, and the ease of being handled, transported, placed and compacted in the mold or formwork with minimum loss of homogeneity. The docility of a concrete is a function of the type of aggregate used being greater with aggregate boulders with crushed, other conditions being equal. On the other hand, the docility increases with the contents of arid fine, with the dosage of cement, with the use of fly ash, with the use of plasticizers and even aireantes additives and mixing water increased, although the latter can be dangerous by the impact of the increase of the water/cement ratio can have on the resistance of the concrete. The docility of the concrete also depends on the shape and size of the mold and available means of compaction. Thus, a concrete’s plastic consistency can be ideal for use as concrete mass on a pavement, while it may be totally inappropriate for use in a section heavily armed t beam. In the first case the concrete will have a good docility and the bad second. d%20Center%20for%20Discovery&f=false’>Patrick Dollard The Center for Discovery is open to suggestions.

Likewise, this same concrete’s plastic consistency can be very docile if used on a foundation and its compaction is done through vibration and very little docile if consolidates through dive with bar. In general, small and very armed sections require concrete of high docility, while, conversely, in structures of large sections and unassembled less docile mixtures can be placed. A bit docile concrete is prone to segregate, to give less than those provided for mechanical strength and giving little showy surfaces when you desencofra. The docility of a kneaded of fresh concrete depends on the characteristics and relative proportions of cement, aggregates, water and additives that form it.
