Recommended Uses
Concrete
General purpose plain and reinforced structural concrete with 28 day
strength levels up to M60.
Special purpose concrete, such as mass concrete, pre-cast concrete,
pumpable concrete, self-compacting and self-levelling concrete.
Cement
To manufacture Blended cements (Portland Pozzolana Cement), such as
sulphate resistant/marine resistant cement.
Mortar
General purpose mortar for plastering and brick/block gluing
Specialised mortars for gluing floor/wall tiles.
Flowable mortars for use as structural fill in earthworks.
Grout
General purpose grouts for use in earthworks for the treatment of rock
cracks.
Grouts for earthworks to be used in anchors.
Recommended Dosages
The dosages of ASHCRETE MM-10 and the other mix constituents should be determined by appropriate mix design testing. They will depend on required mix properties, cement grade and properties, admixtures used, etc. The following figures are indicative.
