Abstract:

Laboratory investigations and results from a year-long field trial demonstrated that plain Type IL cement and slag cement concrete that was internally cured by superabsorbent polymer (SAP) has increased strength and durability compared to SAP-free mixtures, mixtures containing colloidal nanosilica, and mixtures that were externally cured with a surface-applied curing compound. SAP was successfully delivered to fresh concrete mixtures at the ready-mixed concrete plant by using dissolvable bags containing premeasured amounts of dry SAP particles. No batching adjustments were necessary to successfully utilize SAP in the concrete mixtures.
