Description
Hydraulic Setting Compositions
THIS invention relates to hydraulic setting compositions.
In one application of the present invention there is provided a hydraulic setting composition suitable for underground use, for example, for covering tunnel walls for strata control, covering ventilation walls and curtains, as a fire or ventilation sealant for the coating of timber, and as an anti-friction coating of rock and rubble.
The composition according to the invention may also be used in ground and rock stabilisation and consolidation. The composition of the present invention has the advantage of being capable of being applied over polyurethane coatings already present in the mine and may also be used for thermal protection for deep underground application.
The composition on setting has the further advantages of having a low flammability, high flexibility and low toxicology.
It will be understood, however, that the composition is not limited to underground use as it may also be used in other applications.
According to the invention a hydraulic setting composition comprises a hydraulic cement, a suitable aggregate filler material, a polymeric material comprising a water borne copolymer of polyvinylacetate and polyvinylalcohol and a fibrous reinforcing material.
The hydraulic cement may be any suitable cement such- as rapid hardening Portland cement, ordinary
Portland cement or White Portland cement.
Preferably, however, the hydraulic cement comprises white Portland cement. The hydraulic cement may include fly ash as a diluent.
The aggregate may be of a particle size ranging from 15 microns to 3 mm diameter. The aggregate may comprise limestone and/or quartz. Preferably, however, the aggregate comprises calcium carbonate or silica particles or a combination thereof.
The fibrous reinforcing material may comprise mineral or ceramic fibres or the like but preferably comprises glass fibres. In the preferred form of the invention the fibrous material comprises alkali resistant glass fibre of between 6 and 15 mm in length.
Further according to the invention a method of forming a hydraulic setting composition as set out above comprises the steps of [a] forming a dry mix containing a hydraulic
cement, an aggregate filler material and a
fibrous material; [b] adding a water based emulsion containing a
copolymer of polyvinylacetate and polyvinyl
alcohol to the dry mix or vice versa; and [c] intimately mixing the dry mix with the
emulsion to obtain an intimately mixed slurry.
In the method according to this aspect of the invention the emulsion is preferably an emulsion of a copolymer of polyvinylacetate and polyvinylalcohol. The emulsion preferably contains between 30 and 80 solids and preferably has an elasticity on drying of between 80% and 100%. The thermal qualities of the emulsified material are preferably such that degradation only sets in at a temperature in excess of 350"C.
The dry mix preferably comprises white Portland cement, calcium carbonate particles of between 15 microns and 15 mm in size and alkali resistant glass fibres of about 6 to 15 mm in length.
According to a further aspect of the present invention there is provided a method of coating a surface comprising the steps of applying a hydraulic setting material as described above to the surface and allowing it to set. Thus, the coating method may be for the purposes of underground strata control inside mine tunnels or the like whether on existing polyurethane coatings or on virgin rock, for covering ventilation walls or curtains, for thermal protection in deep underground application, for covering timber as a fire sealant, or for covering rock or rubble to prevent friction or any related application. The setting composition may also be used as a grouting material.
An example of the present invention will now be described without thereby limiting the scope of the invention to the embodiment of the example.
EXAMPLE
A two pack pre-mix of a setting composition according to the invention was made up by [a] mixing, by weight, 44 parts white Portland
cement, 56 parts of a calcium carbonate
aggregate of particle size of about 75 micron anff 1 part of an alkali resistant glass fibre
of about 8 mm in length
and [b] diluting 16 litres of a commercially available
adhesive based on polyvinylacetate/polyvinyl
alcohol and sold under the trade name "TAC 615' with 24 litres of water. ["TAC 615" is a
trade description of a commercially available
copolymer . of polyvinylacetate and
polyvinylalcohol marketed in South Africa by
TAC National (Pty.) Limited.]
The two pack pre-mix is mixed on site in the weight ratio of 25:8 dry mix::emlusion and applied to the surface to be treated by means of a suitable nozzled spray gun using compressed air as a carrier medium. Alternatively the composition may be applied by hand such as by brushing, roller coating, or trowelling the composition to the surface to be coated.
Tests done with the above composition confirmed good adherence thereof to various underground surfaces and low flammability and toxiology as well as a high flexibility of the cured composition in use.
Various modifications of the invention may be devised without departing from the spirit of the invention.
Thus the setting rate of the composition may be increased by including a high alumina cement in the hydraulic cement component of the composition.
Furthermore, superplasticisers such as sulfonated melamines [i.e. "Melment F10" as sold by Hoechst AG.i may be incorporated into the composition to reduce water demand and hence to reduce viscosity of the mix and thereby to promote the rate of strength build-up during setting of the composition.
