Abstract

A binder composition comprising 89.4% by weight cement; 4.6% by weight disodium metasilicate; and 6% by weight gypsum.

Description

Binder Composition for use with Aggregates Field of the Invention
This invention relates to binder and binder composition, as well as mixture of said binders with other materials.
Background of the Invention
Binders can be mixed with sub-soil and recycled/primary aggregates to form Stabilised/Hydraulically Bound Materials that can be used as General Fill, Capping, Sub-Base and Base layers in Earthworks and /or Highways and Footpath construction.
These Stabilised/Hydraulically Bound Materials are manufactured/produced to BSEN 14227 parts 1 to 13, the Specification of Highways Works 800 and 600 series, the Specification for Road Openings in the Highways 2010 3rd Edition and any future modification or replacement such standards thereof. It is an object of the invention to provide an improved binder which provides enhanced material properties in the final product.
Statement of the Invention
According to one aspect of the invention is provided a binder composition substantially comprising: between 86.4 and 92.4% by weight cement; between 3.6 and 5.6% by weight additional silicate bearing material; and between 4.5 and 7.5% by weight gypsum, wherein the additional silicate bearing material comprises one or more of disodium metasilicate, sodium metasilicate pentahydrate, tricalcium silicate, dicalcium silicate, calcium silica hydroxide, calcium alumina silica hydroxide, or a combination thereof.
The binder may comprise preferably between 88.9 to 90.9% by weight cement, between 4.1 and 5.1% by weight additional silicate bearing material and between 5.5 and 6.6% by weight gypsum.
The additional silicate bearing material comprises one or more of disodium metasilicate, sodium metasilicate pentahydrate, tricalcium silicate, dicalcium silicate, calcium silica hydroxide, calcium alumina silica hydroxide, or a combination thereof.
The additional silicate bearing material may be provided by silica fume, blast furnace slag, metakaolin, fly ash or a combination thereof.
The gypsum may comprise a mixture of fine casting plaster and recycled plaster/plasterboard.
The casting plaster in the above compositions preferably has a particle size less than 270 microns in diameter.
All proportions given are by weight.
In a further aspect is provided a construction material including a, or formed from inclusion of a binder composition as claimed above. The construction material may be for use in filling or capping of base or sub-base layers in earthworks, highways or footpaths.
Description of the Invention
When added to water cement reacts and forms a hard paste called Calcium Silica Hydroxide (approximately 75%) the other product/compound that is produced is Calcium Hydroxide (approx 25%). Disodium Metasilicate is a different form of silicate to e.g. silicon dioxide but when added to the cement will react with the 25% of Calcium Hydroxide and produce additional cementitious and strength gaining properties.
Disodium Metasilicate is therefore a different compound of silica than that contained in cement but by adding it to the mix it increases/adds to the strength gaining properties of the product and increases the beneficial effects.
The gypsum constituent may be gypsum, fine casting plaster. Preferably the particle size is less than 770 microns diameter, and preferably less than 260 microns diameter.
In a preferred embodiment the gypsum component comprises recycled plaster or plasterboard.
In alternative embodiments the gypsum component may comprise a mixture of casting plaster and recycled plaster material such as recycled plasterboard.
In a specific example, the binder may comprise 89.4% by weight cement, 4.6% disodium metasilicate and 6% gypsum.
In a general example of binder for such applications, the cement content is between 86.4% to 92.4% by weight cement, between 3.6 and 5.6 % disodium metasilicate and between 4.5 and 7.5% gypsum.
Preferably the range varies +/-1% from the specific point example.
