Description
SPECIFICATION
Concrete components
The present invention relates to concrete components particularly but not exclusively structural concrete components such as concrete panelsandto a method of making same.
It is known to used glass reinforced cement in the field of construction technology. Glass reinforced cement comprises cement, either ordinary Portland cement or its derivatives, typically constituting 40 to 60 percent ofthe material by weight, water, typically 20 percent ofthe material by weight, good silica sand, and chopped alkali-resistant glass fibres typically at least 5 percent by weight. The mixture is sprayed into a mould and the glass fibres are randomly distributed in two dimensions in layers throughoutthe thickness of the material and have a length which varies between 10and 40 mm depending on the particular application. The strength of a component made of glass reinforced cement depends mainly on the glass fibre content of the cement.
Glass fibre is expensive and consequently the overall cost of the materials for making components in known glass reinforced cement is high.
According to one aspect of the present invention there is provided a component made from concrete and including at least one layer of elongate glass fibre strips arranged in an orderly manner.
The glassfibrestrips are significantly longerthan the chopped glass fibres used heretofore in glass reinforced cement and preferably have a length of at least 1 00mm.
The fibres are generaliy aligned with the direction or directions of maximum stress and are consequently arranged to extend in a direction parallel or substantially parallel tothe longitudinal extentofthe componentortothelongitudinalextentsofeach part of a component, or are alternatively arranged in grid like manner.
The fibre strips (sometimes referred to in the art as strands) are preferably cut from multi-filament glass fibre roving.
Advantageously, the component comprises two outer concrete layers (conveniently containing only fine aggregate or no aggregate at all), an intermediate concrete layer (containing coarse aggregate), and a layer of elongate glass fibre strips arranged in an orderly manner between the intermediate layer and each outer layer. The outer layers are preferably relativelythin as compared with the intermediate layer and may be outwardly textured. The intermediate layer could contain a light weight infill (e.g. one or more blocks or slabs of expanded polystyrene) to reduce the weight of the component and provide insulation.
The component could also contain steel reinforcing members, in addition to the glass fibre strips.
The invention also resides in the method as set forth in claim 12, preferred and/or optional features ofwhich are setforth in claims 13-16.
The invention will now be more particularly described, byway of example, with reference to the accompanying drawings, in which:
Figure lisa cross-section taken through part of a panel embodying the present invention,
Figure2 is a sectional view along the line ll-ll of
Figure 1,
Figure 3 is a transverse section of the panel shown in Figure 2, on a reduced scale, and
Figure 4 is a cross-section through a further panel embodying the invention.
Referring to Figure 1 of the drawings, the structural component shown therein is in the form of a panel 10 which may, for example, be between 1 Ocm and 5m long and wide and 8mm to 1m thick. The panel comprises first, second and third layers of concrete 11,12 and 13 and two layers 14and 15 of elongate glass fibre strips. The concrete layers 11 and 13 contain only fine aggregate, e.g. aggregate which passes through a 10mum mesh, or no aggregate at all. The layers 11 and 13 are preferably relatively thin in rela tion to the layer 12. Byway of example the layers 11 and 13 may have a thickness of between 3 and 5mm, particularly if the concrete contains no aggregate and is simply a mix of sand cement and water, i.e.
mortar.
The concrete of layer 12 contains coarse aggregate and is therefore a mix of cement, sand, coarse aggregate and water. The layer 12 as shown also contains a lightweightinfill in theform of one or more blocks or slabs of expanded polystyrene, wood, or expanded polyurethane to reduce the weight ofthe panel and provide thermal insulation. The infill, moreover, need not necessarily be in theform of a block or slab, but could instead comprise polystyrene beads mixed with part of the concrete layer 12.
Layers 14 and 15 comprise elongate strips 16 of alkali-resistant glass fibres cut from glass fibre roving (typically having 30-35 filaments) and laid in a neat orderly rather than random fashion. The strips 16 are of significantly greater length than the chopped glass fibres used conventionally in glass reinforced cement. Indeed the glass fibre strips 16 typically have a minimum length of at least 100mm.
The glassfibre strips 16are arranged in grid-like fashion at a spacing of between 10mm and 100mm to extend longitudinally and laterally across the panel as shown in Figure 2. Indeed they may be inthe form of a prefabricated grid or net. The strips 16, as shown, extend continuously across the length and width ofthe panel and if the strips l6areofin- sufficient length to extend across the full length or width two or more strips 16 are arranged in alignment and with a degree of overlap. If the panel is narrow the strips 16may only be arranged longitudinally. The concentration of strips is advantageously increased around the stress points.
The panel shown in Figures 1 and 2 is manufactu redinthefollowing manner.
An open mould is madetothe required shape and is lined with mould oil. The base of the mould is then covered with a thin layer of concrete containing fine aggregate or no aggregate at all otherthan sand, i.e.
simply sand, cement and water. This layer 11 is then compacted using a pneumaticvibratorto ensure a good external finish. Indeed the base ofthe mould could be provided with an appropriately raised pattern to give the external surface of a layer 11 a textu red finish.
Elongate strips 160f glassfibrearethen laid by hand in an orderly fashion, such as in a grid-like fashion as described previously with a higher concentration of fibres at the stress points.
The layer 14 of glass fibre strips is covered with a layer of concrete, having a thickness of between 7 and 10mm, containing a coarse aggregate. The concrete is compacted using a pueumaticvibrator.
One or more blocks or slabs of light infill material, e.g. expanded polystyrene, are then placed on the concrete layer and the infill material is pinned in place by stoppers which depend from crossmembers attached to the top of the mould to prevent the infill material being raised as more concrete is subsequently introduced into the mould. Another layer of concrete is then placed in the mould in order to surround and coverthe infill material. This concrete layer is then compacted as before. The layer 12 of coarse aggregate concrete thus contains the infill material which reduces the weight of the finished panel and provides insulation. The infill material could however be omitted if the weight ofthefin- ished panel is not a problem and if insulation is not required.Moreover, this layer 12 could be built up in further steps to incorporate an additional layer of glass fibre strips.
The layer 15 of glass fibre strips is then laid in similar mannerto layer 14 and the mould is filled with a final layer of fine aggregate concrete and vibrated as before.
Afteraboutonetooneandaquarterhoursthe stoppers are removed and a bonding agent is added to the concrete when the concrete is still green to patch up the holes. The outer surface of layer 13 is then trowelled offto give a smooth finish. The panel is leftforabout 24 hours and is then de-moulded whereupon it is left to cure in water for a few days.
Although this method of making a panel is more labour intensive than making a panel from glass reinforced cement (GRC) it uses much less alkaliresistant glass fibre, 0.2 to 1.5% by weight as compared with 5% byweightfor panels of glass reinforced cement and has a lower cement content. Thusthe material costs are reduced significantly. Moreover, a concrete mix pump is not required.
Due to the prolonged time taken to make up the panel described above it may be necessary to add a retarding admixture to the concrete mix particularly in hot climates.
A panel made according to the above method has a density of about 2,300 Kg/M3 as compared with 2,050 Kg/M3for GRC. The addition of aggregates reduces both the shrinkage rateandthe ultimate shrinkage by acting as a mechanical restraint on the matrix. The panel exhibits high strength both compressive and flexural. Moreover, the load at its LOP (Limit of Proportionality) is at least 70% of the load at its breaking point, rendering it more durable.
Athin section panel can be made utilizing mortar as the outermost layers 11 and 13 and concrete containing only relativelyfine aggregate as the layer 12.
Indeed it is possible in this way to make the panel as thin as 8mm - much thinner than steel reinforced concrete panels. Moreover, the panel is more durable because ofthe non-corrosive nature of the glass fibre strips.
The panel can be of any appropriate shape and can have windows therein if desired. It can have shaped edgestointerlockwith other panels as shown in
Figure3. Fixings and inserts can be incorporated in the panels as desired during moulding.
Thin panels can be made using only two layers of concrete and a single intermediate layer ofglass fibre strips, although a 5 layer panel as described above has greaterflexural strength. Moreover, the panels could bentorfoldedto a chosen shapewhile the concrete is still in the green state.
One or both of the outer layers 11 and 13 ofthe panel described above with reference to Figures 1 and 2 could be omitted. An appropriate finishing layer could be applied later, e.g. on site, if desired.
Steel reinforcing members can be included in addition to the glass fibre strips, particularly adjacent to the longitudinal edges of the panel as indicated by reference numeral 18 in Figure 3, Figure 4, moreover, shows a panel with steel reinforcing members 19 in concrete ribs 20 provided on one side of the panel; the ribs 20 reformed by elongate recesses in the base ofthe mould. These ribs greatly increase the strength ofthin panels. The member 19 could alternatively be glass fibre strips.
The invention is not limited to panels but could be applied to other structural components such as beams, lintels, orto decorative components.
Various other modifications will be apparentto persons skilled in the art without departing from the scope ofthe invention defined by the appended
