The invention provides composite materials comprising novel bonding elements exhibiting unique microstructures and chemical compositions, and methods for their manufacture and uses, for example, in a variety of concrete components with or without aggregates in the infrastructure, construction, pavement and landscaping industries.

Composite materials and bonding elements from carbonation of calcium silicate and methods thereof

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, microstructured clinker and cement materials that are characterized by superior grindability and reactivity. The disclosed clinker and cement materials are based on carbonatable calcium silicate and can be made from widely available, low cost raw materials via a process suitable for large-scale production. The method of the invention is flexible in equipment and processing requirements and is readily adaptable to manufacturing facilities of conventional Portland cement.

Microstructured carbonatable calcium silicate clinkers and methods thereof

The invention provides novel methods and compositions that mitigate the occurrence of hazing of products made from carbonatable calcium silicate-based cements. 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.

Hazing control for carbonatable calcium silicate-based cements and concretes

A process for the treatment of a silicate mineral, includes: preparing a first composition including an alkali metal magnesium orthosilicate and optionally either (i) magnesium oxide or (ii) an alkali metal silicate, by reaction, at a temperature from 500 to 1200&#xb0; C., of an alkali metal carbonate compound, which compound is an alkali metal carbonate, an alkali metal bicarbonate or a mixture thereof, with a magnesium silicate, the molar ratio of alkali metal carbonate compound, expressed as alkali metal oxide of the formula RO, in which R represents an alkali metal, to magnesium silicate, expressed as silicon dioxide, of the formula SiO, being from 4:1 to 1:4, and contacting the first composition with water to produce a second composition comprising an amorphous magnesium silicate hydrate (M-S&#x2014;H).
