Overview
KingAdd 5AW is concrete admixture formulated from selected polymers specially designed to produce more cohesive grouting and concrete mixes. It surrounds the cement particles by gel action to minimise the washout in the underwater cementitioius applications.
Applications
- Underwater concrete applications
- Foundations and piles where high water table occurs
- To produce cohesive concrete mixes
- Fluid grouting that may have subject to washout
Advantages
- Higher concrete strength in the underwater concrete applications by significant minimizing the washout of cement particles
- Improve workability by reducing placing and compaction problems
- Minimizing segregation and bleeding problems by improving cohesion
- More durable concrete as a result of reduction in permeability and lower water to cement ratio
- COMPATIBILITY KingAdd 5AW can be used with all types of Portland cement and cement replacement materials
- KingAdd 5AW is compatible with KINGKRETE concrete admixtures used in the same concrete mix. In case of other types of admixtures have to be used, contact KINGKRETE technical department for more advice

| Air entrainment | Typically less than 2% additional air is entrained above control mix at normal dosages To check the percentage of washout reduction, normally a comparison test should be done between control concrete mix without using KingAdd 5AW admixture versus concrete mix using KingAdd 5AW, fill a perforated basket with concrete mix and drop it through the water for 3 to 5 times and measure the weight loss on each time. Normally up to 90% of washout reduction can be achieved by using the KingAdd 5AW comparing with control mix. | — |
