Heavyweight concrete made of water, cement, and heavyweight aggregate is used for shielding in structures where radiation protection is required. Water reduction helps to achieve high density mixtures, since water is the component with the lowest specific gravity. Thus, the use of superplasticizers helps to obtain workable concrete with low water-cement ratio (w/c) and high density. This paper …
This paper describes how the alkali-silica reaction (ASR) concrete expansion tests at 60°C (140°F) and 100 % relative humidity showed that siliceous limestone aggregates could have pessimum behavior similar to that of flint aggregate. For a given content of alkalis, a concrete made with fine and coarse reactive aggregates expands less than concrete made with reactive fine aggregate and no rea…
