Abstract
The composition comprises a soluble metal silicate, a metal siliconate and a thickening agent. In addition a pigment can be included, for example as a solid in suspension. Examples of said pigment are titanium dioxide or iron(III) oxide. The metal silicate can be selected from an alkali metal silicate and be present in an amount from 20-30% w/w of the composition. The siliconate can similarly be that of an alkali metal and be present up to 5% w/w of the mass of the dried coating. The siliconate, when the composition is dried aids water repellency of the coating. Thickening agents, present from 2-5% w/w of the composition are added to aid even spreading and retention on a surface. The composition when applied to the surface of concrete and reduces efflorescence, maintains concrete strength and reduces staining and growth of algae or lichen.
Description
A COMPOSITION FOR THE TREATMENT OF CONCRETE
Field of the Invention
The present invention is concerned with a composition for use in the treatment of concrete. In particular, the composition disclosed are intended to be spreadable, for example by a brush, roller or the like.
Background to the Invention
The prevalence of concrete products is easy to discern. The reasons for this overall presence are due to the relatively low cost of concrete, its inherent strength and its capacity to be cast into virtually any shape required. Concrete is therefore used in paving, walls and as a support medium for buildings, particularly where strengthened by steel strengthenrng members.
Concrete does however have a number of disadvantages both of a technical nature and an aesthetic nature. Firstly, concrete suffers from a problem commonly known as efflorescence. Efflorescence is discernible on the surface of concrete as a powdery deposit, sometime slightly lighter in colour than the main body of concrete. The problem arises due to water penetration into the concrete through faults in the structure, which water then dissolves soluble salts such as calcium sulphate from the concrete.
As the water and the salts then seep onto the surface of the concrete, the water evaporates leaving the salt behind on the surface. The efflorescence is not only unsightly in itself, but continual removal of the salts from the concrete can lead to weakening of the concrete, with replacement being eventually required.
Secondly, concrete is easily stained by, that is absorbs fairly readily into its surface layers, oil-based products. Two applications where this is especially undesirable are firstly where the concrete is likely to come into contact with such materials: for example on a garage forecourt or on a driveway used to park a vehicle. Oil from vehicles, with time causes a dark stain to become evident, which stain can only be removed with difficulties. Also, the writing of graffiti on the side of a building is often carried out usmg oil-based paints and this makes satisfactory removal of the graffiti problematic: especially without causing damage to the wall or removing an upper layer.
A third disadvantage lies in the aesthetics associated with concrete colour which, if not altered in any way is a grey colour of darker or lighter hue. Coloured concretes are available, in which a colouring agent is mixed in with the liquid pre-concrete mix.
However, the colours applied are themselves not usually especially appealing, being designed to disguise the concrete as a different type of stone.
As is also well known, concrete can also suffer relatively easily from discolouration due to organic growth such as algae or lichen. This problem is particularly acute for concrete paths. A part of the problem lies in the inherent hydrophilicity of the silicates in the concrete which result in a layer of water being bound to the concrete's surface for a longer time than would otherwise be the case. This, together with salts within the concrete leaching to the surface, provides an environment for organic growth causing the well known green discolouration, which is difficult to remove fully.
The prior art discloses a number of ways to address certain of the above problems.
For example stains are provided which penetrate the upper layers of the concrete providing a degree of colour. However, partially in order to provide the colour partially to assist the staining process and also to prevent organic growth, the stains are often relatively acidic or contain salts of toxic heavy metals. These render the stains unsuitable for many applications as the acids or metals can be easily leached into the surrounding area.
It is an object of the current invention to address the above problems and provide a composition which can be easily applied to a concrete surface to protect and to enhance the appearance.
Summaryof the Invention
According to a first aspect of the invention, there is provided a liquid composition for the treatment of a concrete surface, the composition comprising: a soluble metal silicate; a metal siliconate; and a thickening agent.
The composition thus provided enables a coating to be applied to the surface of a concrete object, which coating is hydrophobic and so resists water building up on or penetration into the concrete. Damage to the concrete is thereby reduced.
Optionally, the composition includes a pigment enabling concrete objects to be rendered more aesthetically pleasing and also covering up surface markings on the concrete. The pigment is further optionally a solid material, suspended in the composition Yet further optionally, the pigment is selected from titanium dioxide or iron (III) oxide. Still yet further optionally, the pigment is present in an amount of from 5 -l5%w/w of the composition The silicate is preferably present in an amount from 20 -30%w/w of the composition Particularly preferably, the silicate is an alkali metal silicate to facilitate dissolution of the silicate in the composition Especially preferably, the silicate is potassium silicate, and conveniently Ki 20 or K66. The former of these has a mean weight ratio of Si02:K20 of 1.43, a mean K20 content of 21.6%w/w and Si02 content of 30.8%w/w. The latter has a mean weight ratio of Si02:K20 of 1.33, a mean K20 content of 11.4%w/w and a mean Si02 content of 23.3&w/w.
The metal siliconate is optionally present up to a level of 5%wlw to provide sufficient hydrophobicity in the dried coating. The metal siliconate is further optionally an alkali metal siliconate to facilitate dissolution of the siliconate in the composition.
Still yet further optionally the cation is potassium.
Preferably, the thickener is an inverse emulsion thickener, and is further preferably present in an amount of from 2 -5%w/w of the chosen composition. The thickener is particularly preferably Decal' 1200.
Detailed Description of the Invention
The compositions as herein described are aqueous based liquids and have in general a viscosity greater than that of water which enables the compositions to be spread evenly across a surface. It is also envisaged that the compositions have a degree of thixotropy to retain them in position during the drying process.
Preparation of the compositions is by means of known methodology, to form emulsions and suspensions. Care must be taken during the preparation that hydration and dissolution of the soluble constituents is carried out correctly and that too rapid hydration of the outer regions of particles does not take place leaving a core of relatively dry material.
In order to improve the aesthetic appearance of concrete the compositions can include a colouring agent, distributed evenly throughout its volume. The colouring agent can be dissolved in the aqueous phase of the composition, which allows the colouring agent to be readily evenly distributed and which is unlikely to settle during storage.
Alternatively, colouring agent present in solid form can be employed. For example white titanium dioxide can be used or red iron(ffi) oxide. When using a solid material, the correct particle size needs to be selected to facilitate composition make up and stability. Typically the colouring agent is present in an amount from 5 - 15%w/w of the composition.
One important aspect of the compositions disclosed herein is the property of preventing water penetration into the body of the concrete and also from remaining on the surface for too long a time. The former property prevents serious damage being done to concrete through the presence of water in the interior. Water on the inside can cause a number of problems. Firstly, during cold weather, the water can freeze and in so doing expands, causing stress fractures within the concrete. Secondly, the water can dissolve certain soluble components from the concrete, which can be carried out of the concrete as the water seeps back out. This seepage not only leads to deposits of the salts on the surface of the concrete, known as efflorescence, but can also lead to weakening and ultimately catastrophic failure of the mechanical properties of the concrete.
In order to prevent the entry of water therefore, the composition includes a hydrophobic component. On drying, following application of the composition, the hydrophobic component repels water and prevents it from entering the concrete.
Additionally, water does not spread out so easily across a hydrophobic surface and so water build up is reduced. The drier conditions on the surface of the concrete prevent or slow down the growth of algae, lichen or other organisms on the concrete, which organisms can cause unsightly markings on the concrete and which can be slippery when wet.
In the present compositions the hydrophobic component is a siliconate, preferably an alkali metal salt or mixture of alkali metal salts of the siliconate. The use of an alkali metal salt at least simplifies the dissolution of the hydrophobic siliconate in the aqueous compositions. Of the alkali metals, the potassium salt is preferred as it is more hydrophobic than the sodium salt. Levels of up to 5%w/w of potassium siliconate have been found to be effective.
In order to enable the compositions to have the correct flow characteristics, a thickening agent is included. The compositions need firstly to be sufficiently viscous so that they can be spread easily across a surface to yield a good coat. Secondly, the compositions are advantageously thixotropic to minimise their flow once they have been applied. This is especially of advantage when the coating is on a vertical surface. The thickening agent can be an inverse emulsion thickener such as Decal 1200, available from Devine Chemicals. Levels of from 2 -5%w/w of the composition have been found to be effective.
Silicate is included in the compositions to adjust the pH of the compositions and also because of the compatibility of silicates with concrete. The silicate also acts to an extent as a viscosity moderator, raising the viscosity above that of water. Silicates are therefore added in an amount of from 20 -30 %w/w of the composition. In order to enable sufficient silicate to be used, the silicate is selected to be an alkali metal silicate and preferably potassium silicate. As examples of silicates which are suitable are those marketed under the designations K120 and 1(66.
It will of course be understood that the invention is not limited to the specific details described herein, which are given by way of example only, and that various modifications and alterations are possible within the scope of the invention.
