Abstract
A sand aggregate includes plural aggregate grains, wherein at least one aggregate grain of the plural aggregate grains includes, desert sand grains that are too small to be used in concrete applications, carbonate particles distributed on an external surface of the desert sand grains, and a sand-based glue that aggregates the desert sand grains together. The at least one aggregate grain has a size comparable to river sand grains, while the desert sand grains have a size smaller than the river sand grains so that the at least one aggregate grain is suitable for concrete applications.
