Description
Estogrout Admix is an admixture for cementitious grouts where a low water : cement ratio and positive expansion are required.
It is a combination of plasticizing agent and a gas producing expansion medium. Sufficient restrained expansion is developed to ensure a high degree of interfacial contact.
If pre-packed cement based grout is required instead of an admixture, use Estogrout FP 70, MP 70 or MP 60, which only required additional of water.
Estogrout Admix has been tested by SIRIM BHD in accordance to ASTM C940:1998, on Expansion and Bleeding Test, Potentiometric Method, on Determination of Chloride Content, and complied with the specification in this data sheet.

Over Dosing
Drastic overdosing of Estogrout Admix increases expansion and may cause severe strength lost.
Mixing
For best results a mechanically powered grout mixer must be used. For quantities up to 50kg a slow speed drill fitted with a high shear paddle is suitable. Larger quantities will require a high shear vane mixer. It is essential that machine mixing capacity and labour availability is adequate to enable the grouting operation to be carried out continuously. This may require the use of a holding tank with provision for gentle agitation to maintain fluidity.
The selected water content should be accurately measured into the mixer. Slowly add the cement (and sand if required) and Estogrout Admix. Mix continuously for 5 minutes, making sure that a smooth even consistency is obtained.
Application
After mixing, areas to be grouted should be prepared in the usual way to ensure, clean, sound, pre-wetted substrates. Place the grout within 20 minutes of mixing to gain the full benefit of the expansion process. Adopt usual placing or pumping procedures ensuring a continuous operation.
Curing
On completion of the grouting operation all exposed areas that are not to be cut back should be thoroughly cured. This should be done after the initial hardening of the grout by continuous application of water or by application of suitable curing membrane such as Estocure product range.
