The invention provides novel methods and novel additive compositions and use thereof in a wide range of concrete production for improving properties of concrete materials, such as durability and aestheticity. The methods and compositions of the invention may be applied in a variety of cement and concrete components in the infrastructure, construction, pavement and landscaping industries.

Carbonatable calcium silicate-based cements and concretes having mineral additives, and methods thereof

Carbonatable calcium silicate-based cements and concretes are presented, which result in concrete compositions that have an improved aesthetics. A cement product includes a plurality of particles of a carbonatable calcium silicate cement and a first additive; wherein, the first additive is a hydrophobic organic acid, or a salt thereof, or a silane, or a polysiloxane.

Compositions and method to improve the aesthetics of calcium silicate-based cements and concretes

Calcium silicate-based cements and concretes are disclosed, which result in concrete compositions that have an improved strength development. A cement product includes a plurality of particles of a carbonatable calcium silicate cement and a first additive; wherein, the first additive is an organic molecule with at least one primary, secondary or tertiary amine group.

Compositions and method to improve the strength development of calcium silicate-based cements and concretes

Calcium silicate-based cements and concretes are disclosed, which result in concrete compositions that have an increased durability. A cement product includes a plurality of particles of a carbonatable calcium silicate cement and a hydrophobic organic acid, or a salt thereof, or a silane, or a polysiloxane.

Compositions and method to improve the durability of calcium silicate-based cements and concretes

The invention provides novel paving stones and construction block composite materials and methods for preparation thereof. The paving stones and construction block composite materials can be readily produced from widely available, low cost precursor materials by a production process that involves compacting in a mold that is suitable for large-scale production. The precursor materials include calcium silicate, for example, wollastonite, and particulate filler materials which can comprise silicon dioxide-rich materials. Additives can include calcium carbonate-rich and magnesium carbonate-rich materials. Various additives can be used to fine-tune the physical appearance and mechanical properties of the composite material, such as colorants such as particles of colored materials, such as, and pigments (e.g., black iron oxide, cobalt oxide and chromium oxide). These paving stones and construction block composite materials exhibit visual patterns similar to stone as well as display compressive strength and water absorption equal to or better than that of stone.

Pavers and block composite materials and methods of preparation thereof

The invention provides novel aerated composite materials that possess excellent physical and performance characteristics of aerated concretes, and methods of production and uses thereof. These composite materials can be readily produced from widely available, low cost raw materials by a process suitable for large-scale production with improved energy consumption, desirable carbon footprint and minimal environmental impact.

Aerated composite materials, methods of production and uses thereof

The invention encompasses equipment used to condition a recirculating gas stream in order to cure a COComposite Material (CCM) and processes that use such equipment to cure the CCM. The gas conditioning equipment allows for a process that controls, reduces or eliminates the rate-limiting steps associated with water removal during the curing of a composite material. The equipment may include, but will not be limited to, control over the temperature, relative humidity, flow rate, pressure, and carbon dioxide concentration within the system; which includes the conditioning equipment, any vessel containing the CCM, and the material itself. Flow rate control can be used as a means to achieve uniformity in both gas velocity and composition.

Method and apparatus for the curing of composite material by control over rate limiting steps in water removal

The invention provides novel carbonatable calcium silicate compositions and carbonatable calcium silicate phases that are made from widely available, low cost raw materials by a process suitable for large-scale production. The method of the invention is flexible in equipment and production requirements and is readily adaptable to manufacturing facilities of conventional cement. The invention offers an exceptional capability to permanently and safely sequesters CO.

Carbonatable calcium silicate compositions and methods thereof

A method of preparing and rapidly curing a composite material having a thin cross section. The composite material includes a mixture of solid particles, at least some of which are a material that reacts with CO, such as a silicate, for example Wollastonite. The green material is prepared by mixing the solid components with a liquid such as water to form a slurry, and forming green bodies by placing the slurry in forms. The green bodies are reacted with COto form cured composite materials having thin sections, in the range of 10 to 15 mm. Curing in periods of 6 hours has been demonstrated.

Rapid curing of thin composite material sections

The invention provides novel pervious composite materials that possess excellent physical and performance characteristics of conventional pervious concretes, and methods of production and uses thereof. These composite materials can be readily produced from widely available, low cost raw materials by a process suitable for large-scale production with improved energy consumption, desirable carbon footprint and minimal environmental impact.
