Abstract
Provided herein are compositions, methods, and systems related to aggregates, such as e.g., lightweight aggregates, formed from the reactive vaterite cement compositions.
Claims20
An aggregate, comprising:
- interlocking acicular shaped aragonite, wherein the aggregate has porosity of between about 10-90% and/or bulk density of between about 25-110 lb/ft3.
A method of forming aggregates, comprising:
- (i) preparing a wet composition comprising reactive vaterite cement and water, by adding water to a composition comprising reactive vaterite cement;
- (ii) depositing the wet composition layer by layer that agglomerates to form aggregates;
- and
- (iii) curing the aggregates to transform the reactive vaterite cement into interlocking acicular shaped aragonite to form aggregates.
