Multi purpose Shrinkage Compensated Grout

Download Data Sheet
Category: .

Description

Estogrout MP 70 non-shrink grout provides high flexural and compressive strength performance. It is a ready to use product in powder form and requires addition of water to produce as non-shrink grout performance.

Estogrout MP 70 is a blend of Portland cement, graded fillers and chemical additives that impart controlled expansion in the plastic state whilst minimizing water demand. The low water demand ensures high early strength. The graded filler is to assist uniform mixing and produce a consistent grout.

Estogrout MP 70 has been tested by SIRIM BHD in accordance to BS 6319, on Compressive Strength Test, ASTM C 940-98, on Expansion & Bleeding Test, and complied with the specification in this data sheet.

Application Instructions

Preparation
Foundation Surface

The surface of the substrate must be sound and free from oil, The surface of the substrate must be sound and free from oil, grease or any loosely adherent material. Bolt holes and fixing pockets must be blown clean of any dirt or debris. To assist in the formation of bond between substrate and grout, pre soaking of the substrate surface with water is advisable.

Base Plate

It is essential that this is clean and free from oil, grease or scale. Air pressure relief holes should be provided to allow venting of any isolated high spots.

Formwork

All formwork used for grouting should be leak proof. This can be achieved by sealing it with a foam rubber strip or sealant.

Mixing & Yield

The quantity of clean water required to be added to a 25kg bag of Estogrout MP 70 to achieve the desired consistency is

Consistency Water Yield
Trowelable 3.5-3.75 litres 12.20 litres
Flowable 4.5-5.0 litres 13.30 litres

Application

Estogrout MP 70 can be placed in thickness up to 100mm in a single pour when used as an under plate grout. For thicker sections, it is necessary fill out the Estogrout MP 70 using the well-graded silt free aggregate to minimize heat build up. Typically, a 10mm aggregate is recommended. Quantities of aggregate added to the Estogrout MP 70 should not exceed 1 part aggregate to 1 part of Estogrout MP 70 by weight.

Estogrout MP 70 is pumpable. Contact Estop Technical Department for details of suitable pumping equipment.

Curing

On completion of the grouting operation all exposed areas, which 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 compound such as Estocure Product Range.

Packing & size

Estogrout MP 70 25 kg bag
