Aggregate water absorption
Aggregate water absorption
(OP)
What are the main problems associated with using an aggregate in a marine environment with a water absorbtion of 4.5% say? Usually less than 3% is required. Can the concrete design be changed to accomodate for this poor quality in the aggregate? Thanks in advance.





RE: Aggregate water absorption
There are mitigation techniques such as Nitrite additives to reduce the corrosion potential. Keeping a low water-cement ratio and making the quality of the concrete as high as practicable will also help mitigate the effect of aggregates of this type.
