Influence of the Extra Water Additional to the Total Shrinkage of High-Strength Lightweight Aggregate Concrete
Abstract: The effect of extra mixing water on the slump of the concrete mix, the mechanical and deformation properties (autogenous and drying shrinkage) of high-strength lightweight aggregate concrete are investigated. It is established that the addition of extra mixing water, increases the actual value of water-cement ratio to 0.41, however, does not reduce the index of compressive strength of the concrete. The value of concrete autogenous shrinkage with an addition of extra mixing water at the age of 28 days is 50% less than shrinkage of concrete without additional water. The total shrinkage of lightweight concretes with addition of extra mixing water is 16% below the composition without adding.
Keywords: slump, autogenous shrinkage, drying shrinkage, high-strength lightweight aggregate concrete, superplasticizer.
