Estop Admix AP is a liquid water reducing set accelerator for concrete and mortar, formulated from carefully selected active ingredient.
Estop Admix AP is a cement dispering agent which acts as a catalyst and produces high early strength concrete. It reduces the water cement ratio, accelerates the initial set, increases durability, reduces shrinkage and improves workability.
|Specific Gravity at 25°C||1.12|
|Viscosity (cP) at 25°C||1.39|
Estop Admix AP in required to be dispred in water prior to addition to the concrete and Portland cement mortar mixes.
If added to transit or ready-mix truck, minimun one minute mixing is required before discharging.
The effect of Estop Admix AP depend on variables such as cement composition, ambient temperature and mix design. It is recommended to carry out trials for determining the dosage required.
Under normal circumstances, the dosage shall be 0.6% to 1.2% of the total cement content.
Overdosing will generally produce considerable increase in workability and will accelerate the setting and hardening process. In no circumstances should the dosage rate exceed 2.5 litre per 50kg of cement.
Estop Admix AP is generally compatible with general air entraining agents, retarders and fly ash. Other admixtures may be used with Estop Admix AP subject to prior consultation our technical department.
The following data are compiled from our investigations and laboratory testing. It is to illustrate the effects of Estop Admix AP on concrete mixes and use as guides for your own trial mixes.
|Dosage Rate / 50 kg OPC||Initial Set (hrs)||Final Set (hrs)|
|Control mix||3 ½||5 ½|
|300 cc||1 ¾||3 ¾|
|600 cc||1 ¼||2 ½|
|Estop Admix AP||20 litre|
