Concrete & Mortar Durosil DR11 & DR6
is a non-cementitious, chemically bonded concrete with a high silica
content (99%), it is highly resistant to all acids bar hydrofluoric
but is unsuitable for contact with alkali applications. It is equally
effective in weak acid and strong acid and unlike conventional silicate
based products, it is totally unaffected by water.
is suitable for total immersion application as well as secondary
containment and at all concentrations and temperatures. It has low
permeability and as there is no apparent cracking or shrinkage,
the need to install a membrane is avoided.
can be laid as a screed (minimum thickness 40mm), cast and vibrated
behind shutters, or made into pre-cast shapes. Due to its hardness
(Moh 7) it is eminently suitable for making weir wall or guide blocks
in pickle tanks. Special shapes for gullys, troughs and sumps can
be made in days rather than weeks needed for ceramic earthenware.
mortar exhibits all the properties of the concrete and with its
excellent adhesion to earthenware can be substituted for Furane
Resin with the advantages of lower costs and no hazardous fumes.
It can also be laid on a damp substrate.
are supplied in bags of graded aggregates and pre-measured quantities
of liquid in plastic containers. No other additives are needed and
both products can be mixed easily with conventional equipment. Tools
and plant can be cleaned with water.
