Abstract

A material for bricks, lintels and like building components comprises at least a major portion of granular or powder material (preferably crushed sea shells such as scallop shells) mainly or entirely comprising calcium carbonate. A proportion of a binder such as a standard lime-based building cement powder (Portland cement) is admixed with the crushed sea shells preferably in the proportions 921 DIVIDED 2% shell material to 71 DIVIDED 2% cement.

Description

SPECIFICATION Bricks and like building construction components This invention relates to bricks and like building components such as lintels, screening blocks, paving stones and insulation blocks which are conventionally produced from various aggregates of cement, sand and possibly stone chips.
According to a first aspect of this invention there is provided a building construction component having a composition comprising at least a major proportion of granular or powder material mainly or entirely comprising calcium carbonate and a proportion of a binder also being included.
Preferably the granular or powder material is produced by crushing and/or grinding the shells of sea creatures. The building construction component may include a proportion of cement as binder suitable proportions by weight being 9221% of the shell material and 721% cement.
According to a second aspect of this invention there is provided a method of producing a building construction component and including the steps of mixing a major proportion of granular or powder material mainly or entirely comprising calcium carbonate with a proportion of a binder, and treating and shaping the mixture so obtained so as to obtain a solid building construction component.
Where the granular or powder material is a shell material e.g. shells of sea creatures, the method includes the step of reducing these by grinding and/or pulverising to the desired state.
Preferably the binder is cement, and water is added to enable setting of the cement, the shaped building component being allowed to set or being cured in a conventional manner.
An embodiment of this invention will now be described with reference to the following example.
Scallop shells (comprising approximately 99% calcium carbonate) are ground to granular form (with a maximum grain size of 19 mm) and screened for the purposes of grading and the granular shell material so obtained is then mixed with a standard lime-based building cement powder (i.e. Portland cement) in the proportions 923% shell material to 7 2% cement. The two ingredients are then mixed in the dry state after which water is added to enable the cement to carry out its binding action and the resulting wet mixture is then put into moulds where the bricks are allowed to set in the normal manner.While simple moulding in this way is appropriate in many cases, it may be desirable to adopt a more complex shaping and setting process as, for example, vibratory moulding, moulding under pressure and curing by means of heat, in any appropriate combination if required.
The resulting bricks are found to provide satisfactory strength properties combined with a moisture resistance in the form of low porosity and an improved thermal efficeincy as compared with conventional bricks.
While the proportions of shell material and cement can be varied, the proportion of shell material should form at least a major proportion of the brick composition.
Accurate colouring of the bricks can be obtained by using dyes on the shell material before mixing with cement.
Shells or other sea creatures can be used instead of or in addition to the scallop shells and in fact any granular or powder material mainly or entirely comprising calcium carbonate is considered useful in this context. Building construction components other than bricks can be produced for example lintels, screening blocks, paving stones and insulation blocks.
While cement is the binder of main interest it is to be appreciated that other types of binders may be used for appropriate applications.
Claims
1. A building construction component having a composition comprising at least a major proportion of granular or powder material mainly or entirely comprising calcium carbonate and a proportion of a binder also being included.
2. A building construction component according to claim 1 wherein the granular or powder material is produced by crushing and/or grinding the shells of sea creatures.
3. A building construction component according to claim 2 wherein the building construction component may include a proportion of cement as binder suitable proportions by weight being 922% of the shell material and 72% cement.
4. A building construction component substantially as described herein with reference to the example given.
5. A method of producing a building construction component and including the steps of mixing a major proportion of granular or powder material mainly or entirely comprising calcium carbonate with a proportion of a binder, and treating and shaping the mixture so obtained so as to obtain a solid building construction component.
6. A method according to claim 5 wherein the step is included of reducing shells of sea creatures to a granular or powder form to provide said granular or powder material.
7. A method according to claim 5 or claim 6 wherein the binder is cement, and water is added to enable setting of the cement, the shaped building component being allowed to set or being cured in a conventional manner.
8. A method of producing a building construction component substantially as described herein with reference to the example given.
