Fine-Aggregate Concrete. A disadvantage of fine-aggregate concrete is the increased consumption of binder compared to other types of concrete and the associated greater shrinkage and creep. The quantity of binder in the concrete can be reduced by pulverizing some of the sand, by the use of plasticizers, or by autoclaving of products.
