Control concrete workability with one versatile water-reducing admixture. SikaPlast® 3-in-1 is a neutral-set liquid admixture for premix and precast concrete. Depending on the mix design and dose, it can provide normal, mid-range or high-range water reduction.
Key benefits
- Flexible water reduction: adjust workability and water demand across different concrete mixes.
- Neutral setting: manage acceleration or retardation separately where required.
- Production versatility: suitable for specified premix, precast and post-tensioned concrete.
Application
Determine the correct dose through mix trials and introduce with batching water. Follow the current technical data sheet for dosage ranges and compatibility with companion admixtures.
Important to know
Do not add directly to dry materials or combine with Sikament® NN. Test air entrainment and setting behaviour before production.
Neutral-set water reduction for premix and precast concrete.
Can be dosed to suit different water-reduction targets and required workability.
Allows setting control to be considered separately from water reduction.
Select the water-reduction range for the target concrete mix, then determine the optimum dose through laboratory or site trials. Introduce SikaPlast 3-in-1 with the batching water, never to a dry mix. Add companion admixtures separately and confirm the effect on workability, set time and entrained air before production.
Do not add directly to dry ingredients. Not compatible with Sikament NN according to Sika's Australian product sheet. Add other admixtures separately. Air-entraining admixtures can lead to a significant increase in entrained air: trial concrete mixes. Dose ranges are indicative, not universal prescriptions.
