Liquid AEA air entraining admixture for mortar from UK Construction Products

Liquid Mortar Admixtures

Liquid AEA

Liquid AEA is a liquid air entraining admixture for mortars, dosed with the mixing water. As an air entrainer, it is designed to stabilise very small air bubbles in the mix, which typically improves workability and cohesion. Results depend on the mix, so trial it with your own materials.

What is in the liquid solutions range?

Concrete admixtures

  • SP10: mid range water reducing superplasticiser.
  • SP20: high range water reducing superplasticiser.
  • HP-Xcel: chloride free concrete accelerator and low temperature plasticiser.

Why choose a liquid format?

Liquid admixtures are added with the gauging water, so they disperse quickly and evenly through the mix. They suit batching plants and precast lines with liquid dosing equipment, and larger users can take many products in 1000 litre IBCs to reduce handling.

If you need an additive built into a dry product, see our powder solutions.

Technical support and bespoke formulation

Getting the best from an admixture depends on your cement, aggregates, equipment and conditions. Our technical support team can advise on dosage, mix design and application, and the technical datasheets summarise each product.

UKCP has over 30 years' technical experience developing additives and admixtures for dry mortars, silo mortars and concrete applications. Where a standard product is not the right fit, our in-house development team can create bespoke "black box" additives in liquid or powder form. To try a product with your own materials, request a sample.

Liquid Solutions FAQs

Answers to common questions about this collection. For advice on a specific mix or project, contact our technical team.

What are liquid admixtures?

Liquid admixtures are materials added in small quantities to a concrete, screed or mortar mix, usually with the mixing water, to change its properties. UKCP liquid admixtures reduce water demand, accelerate set and strength gain, improve compaction, speed up screed drying or entrain air in mortar.

Which UKCP liquids are not admixtures?

Release agents (Eco-lease RB, MRA EF and MRA1) are applied to formwork and moulds. Protekt protects plant and equipment from concrete build up and Concremove removes hardened concrete. BlokSeal is applied to finished blocks and bricks, and AcryMul50 is a multipurpose acrylic binder.

How are UKCP liquid products supplied?

Pack sizes vary by product. LSA Max comes in 20 litre and 200 litre drums and 1000 litre IBCs, CompaktAid and CompaktAid Plus in 200 litre drums and 1000 litre IBCs, and BlokSeal and AcryMul50 in 1000kg IBCs and bulk. Contact us for other pack sizes.

Should I choose a liquid or powder admixture?

Liquid admixtures suit plants with liquid dosing equipment and site mixing, because they are added with the water. Powder products suit dry mix and bagged product manufacture and pre-measured site dosing, such as PSA sachets.
