Abstract

Abstract A combination of compositions, products and methods of producing a new type of cement. The cementitious material is created by adding sodium carbonate (also known as soda ash, trona, natron, sodium carbonate decahydrate, sodium carbonate anhydrous, etc.) and one or more rocks or minerals selected from the following—granite, basalt, sandstone or schist. A new method and product are claimed by combining sodium carbonate and one or more rocks or minerals selected from the following—granite, basalt, sandstone or schist and water. The combination of sodium carbonate and one or more rocks or minerals selected from the granite, basalt, sandstone or schist group can be either layered or mixed in a dry or wet state. An exothermic reaction starts after the addition of water to the cementitious material. The composition of the cementitious material can vary between 10 % sodium carbonate and 90 % of one or more rocks or minerals selected from the granite, basalt, sandstone or schist group to 90 % sodium carbonate and 10 % of one or more rocks or minerals selected from the granite, basalt, sandstone or schist group. Organic or inorganic additives may be added to the mixture to enhance the composition and/or the final hardened product. The cementitious material or products can be used in a variety of applications not inclusive of forming bricks, interior architecture, table or counter tops, ornaments, repairing damaged cement products, casting, bioabsorbable devices, extruded products, sprayed products, filler, grout, mortar, gunnite, moulded products, composites, cast stonework, agglomerated stone, concrete, hardened products, electronics, packaging and other applications not mentioned above.

Claim 6
Dependent Claim 10 words
The cementitious product according to claim 1 in hardened form.
Claim 7
Dependent Claim 36 words
The cementitious product of claim 1 , wherein said sodium carbonate and said one or more rocks or minerals selected from the group consisting of granite, basalt, sandstone and schist appear as layers in said product.
Claim 8
Dependent Claim 36 words
A solid product comprising at least one aggregate selected from the group consisting of bedrock, traprock, quartz, quartzite, marble, limestone, calcite, dolomite, chrysocolla, malachite, biotite and feldspar bonded with the cementitious product of claim 1 .
Claim 9
Dependent Claim 34 words
