Abstract:
Admixtures are not just additives—they are performance enhancers that can improve workability, accelerate or reduce setting times, prevent cracking, enhance durability, and extend service life. By collaborating with trusted material suppliers and staying informed about developments in admixture technology, project teams can develop mixture designs that are tailored to site conditions.

This article discusses air-entrained concrete, advantages of air entrainment, the effects of supplementary cementitious materials (SCMs) on the air-entraining admixture (AEA) dosage, and the effects of production and construction variables on air content. It explains parameters such as total air content, air-void size and distribution, spacing factor, and specific surface, and summarizes testing methods and relevant specifications, as well as alternatives to AEA.

Abrasion caused by moving equipment or flowing water can wear away concrete’s surface and render it unfit for service. Kryton International’s Hard-Cem®, an integral hardening admixture based on a unique mineral-metal particle, offers a solution. Its tough microstructure can double the resistance of concrete to abrasive and erosive wear.

This article provides an overview of a hydration-controlling (stabilizing) admixture and its use for recycling returned concrete. It includes details on a robustness evaluation of stabilization performance in a unique cross-country experiment, as well as information on the potential for lowering the environmental impacts of concrete production.

The presence of chloride ions is one of the most widespread causes of corrosion initiation in reinforcing steel in concrete. Trace chlorides present in cementitious materials or admixtures typically result in very low fresh chloride contents in normal-strength concrete that do not present a danger of corrosion. UHPC mixture designs, however, use much higher dosages of cementitious materials and admixtures that can result in non-negligible total fresh chloride contents. These high chloride values are likely to occur more frequently in the future as more UHPC mixtures are made with locally available materials and alternative cementitious materials and may result in concrete mixtures failing to meet specifications for fresh chloride content limits that are based on mixture proportions used in normal-strength concrete mixtures. UHPC and normal concrete samples were made without fibers and with increasing levels of internally admixed chlorides for four different levels of strength to determine chloride thresholds for internally added chlorides. The chloride threshold for fresh concrete was measured using a slightly modified version of the accelerated test EN 480-14. The water-soluble and acid-soluble chloride ion content of UHPC mixtures tested were measured according to ASTM C1218 and Florida Method FM 5-516 to determine the bound chlorides and fresh chloride limits for corrosion. The results demonstrate that the UHPC had ~ 25% higher chloride threshold than the control mixture when measured as an absolute content per unit volume of concrete. When the UHPC chloride content is normalized by mass of cementitious material, it was found that the amount needed to initiate corrosion may be lower than fresh chloride limits given in ACI-318 and ACI 222. Therefore, the ACI-318 water-soluble chloride limits as a % by mass of cementitious materials were found to be non-conservative for the two of the UHPC mixtures tested and should be re-examined for UHPC.
