Definitions
- Sprayable compositions have the advantage that they can e sprayed directly onto an uneven surface without need for smoothing or lathing prior to mounting of elements with a certain form and size. Transport is also simpler since it is bulk and not in the form of large elements requiring mechanical handling prior to and during mounting.
- the disadvantage with sprayable compositions has until now been that it has not been possible to make such compositions comply with the demands to safety that exists for the most relevant fields of use.
- the coating should have good safety in relation to fire and good properties in relation to water and frost. It is furthermore an object to be ale to make or prepare the coating by means which are inexpensive and flexible and which do not require extensive adaptations or "tailoring" for each individual application.
- the present invention provides a method as defined by claim 1.
- the present invention provides a coating as defined by claim 25.
- Preferred, non-limiting embodiments of the invention are disclosed by the dependent claims.
- micronized is understood a powdery form in which the particle size is in the range up to about 200 ⁇ m (micron).
- a certain compound like aplite, is mainly within a defined particle size range, it is to be understood that at least 50 % by weight of the particles is in that range and preferably at least 80 %.
- Aplite is a granite rock mainly consisting of quartz and feldspar. It occurs in different continents and is available in different qualities. Aplite is e.g. found in adjoin, Virginia, USA, Owens Valley, California, USA, Finnvolldalen in Norway, in Toscana in Italy and some places in Russia and Japan. Commercially, aplite is delivered from a.o. Maffei
- Aplite typically contains silicon, magnesium, iron, sodium, aluminium, potassium, titanium and calcium, the main constituents being silicon and aluminium (in the form of oxides) typically being present in relative amounts in the range 60-85 % by weight and 10-25 % by weight respectively.
- Suitable carbon fibres in the form of a separate mass or in a structured form, like woven or knitted mats, for use with the present invention can be supplied commercially from e.g. Devoid AMT, Langevaag, Norway.
- quartz content in the aplite calculated as SiO 2 stake, within the rage 68 to 95 % by weight.
- the first layer when hardened, constitutes a very strong concrete with a compressive strength of up to 700 bar or more. With a convenient amount of aplite this layer will not draw water from the surface beneath (the matrix) if seepage of water to this layer should occur.
- the second layer contributes to increased strength n the form of tensile strength and ductility and contributes to form a strong bonding between the first and the third layer.
- the second layer contributes to increased stability of the coating and the coating structure with time.
- the third layer primarily contributes to prevent any propagation of heat in the form of open flames, since it is able to resist heat without burning or disintegrating.
- the content of significant amounts of slag, preferably crude ore slag and calcite (CaCO 3 ) and anhydrite (CaSO 4 ) makes this layer a fire-proof barrier.
- a typical and preferred layer thickness of the first layer is from 50 to 150 mm. This also applies for the third layer.
- a water content in the range 40-50 % by weight of the dry substances is typically present in the settable material composition.
- the micronized aplite mainly has a particle size less than 250 ⁇ m, preferably in the range 150-170 ⁇ m, but may also be less than 150 ⁇ m and in some cases less than 100 ⁇ m. In some embodiments it is preferred that at least 80 % o the aplite has a particle size less than 200 ⁇ m and in some embodiments it is preferred that at least 50 % of the aplite has a particle size less than 100 ⁇ m.
- particle size it should be understood if nothing else is stated, that ii is measured by conventional measurement techniques and standard sieve sizes. Alternatively the particle size could be determined with Coulter set of apparatus for determination of particle size.
- the micronized aplite has a quartz content of at least 68 % by weight and more preferred at east 75 % by weight of the aplite.
- the micronized aplite can be present as the sole cement component in the composition used in the first layer, i.e. as the only bonding agent in the first layer and that the reaction that causes the layer to set is controlled by adjusting pH in the settable composition to a level lower than 7, preferably lower than 5 and readily lower than 4. Such adjustment can - be made by adding a controlled amount of a mineral acid or organic acid. Any acidizing component that not adversely effects other components in the composition can be used.
- aplite can be used in the first layer along with at least one hydraulic cement, like a Portland cement, pozzolan cement, gypsum cement alumina cement silica cement and slag cement.
- Such conventional hydraulic cement is typically present in the first layer in an amount in the range 15-35 % by weight of the total cement material (aplite + conventional cement material).
- aplite + conventional cement material typically of a diameter in the range from about 5 ⁇ m to about 200 ⁇ m.
- micro-spheres contribute a.o. to improved flowing ability of the fresh settable material composition used to form the mentioned first layer and the mentioned third layer.
- the micro-spheres can also positively influence the strength properties and/ or other properties of the final, hardened composition constituting a layer of the coating according to the second aspect of the present invention.
- the micro-spheres can be made in materials chosen among glass, ceramics, polymers and carbon fibres.
- the fibres of the reinforcement layer solely comprise fibres which are non-corrosive even in an acidic environment and are preferable carbon fibres.
- the fibres are preferably arranged in a structured form, such as, but not limited to, woven, knitted or braided form.
- the fibres typically have a diameter in the range 1-15 ⁇ m, more preferred 3-10 ⁇ m, and most preferred 6-8 ⁇ m.
- fibres such as carbon fibres are present as discrete fibres in the compositions forming first and/ or third layer, they preferably have a length in the range 1-100 mm and more preferred 3-25 mm.
- the relative amount of anhydrite present in the composition forming the third layer typically is in the range 2-5 % by weight of the dry substance.
- the relative amount of calcite in the composition forming third layer also is in the range 2-5 % by weight of the dry substance.
- the particle sizes of anhydrite and calcite are less important than the particle size of aplite and will generally have a rather broad distribution in which most of the material, typically 70-80 % thereof, within the range 0.1 - 5 mm.
- Micronized aplite can be present as the sole bonding agent (cement component) in the composition used to form the third layer and the reaction causing the layer to set is controlled by adjusting pH of the settable material composition to a value lower than 7, preferably lower than 6, and more preferred lower than 5.
- micro-spheres having a typical diameter in the range from about 5 ⁇ m to about 200 ⁇ m can be included as well as discrete carbon fires as mentioned in relation to the composition of the first layer.
- the matrix or the surface onto which the first layer is applied is typically an internal mountain wall that has been exposed by a technique chosen among drilling and blasting and optionally subsequent washing or cleaning, most typically wall surfaces and/ or ceiling surfaces in a tunnel, typically a tunnel for transportation, such as for roads or railway.
- the invention comprises a complete coating comprising at least three layers formed by any combination of the features described in connection with the method constituting the first aspect of the invention.
- the coating which is particularly suited as a fire, frost and water-proof coating in tunnels, thus comprises a first layer of a set material composition comprising micronized aplite, another layer in the for of a reinforcement layer and a third layer of a set material composition comprising aplite, anhydrite, slag and calcite.
- the coating according to this aspect of the invention thus comprises the respective stakes of the individual components which above have been defined with reference to the method constituting the first aspect of the invention.
- Aplite from all known occurrences can be used though it is preferred that the aplite has a silicate (quartz) content of at least 68 % by weight and more preferred at least 75 %.
- At least one of the layers chosen among first and third layer can include aplite granulate as an aggregate.
- materials chosen from materials like sand, gravel, anhydrite, glass, and foamed glass can be used as aggregate in the first and third layers.
- the coating according to the present invention will during setting typically shrink less than 3 %, preferably less than 1.5 % and most preferred less than 0.7 %.
- the method and the coating according to the present invention can be well suited for a number of applications of which the most obvious today is for coating of wall tunnels, particularly road tunnels with coatings that fulfil the strict demands for safety in the fields water, frost and not least fire.
- composition according to the invention satisfies such demands since especially the third layer with its content of slag, aplite, calcite (CaCO 3 ) and anhydrite (CaSO 4 ) form a strongly fire resistant barrier while the other layers contribute to provide strength to the structure.
