Self-curing concrete comprising a metal-organic framework and methods of making the same

Abstract

The present disclosure discloses a method of forming self-curing concrete comprising the steps of mixing cement, aggregates, and dry MIL-101(Cr) metal-organic framework (MOF) to form a mixture, incorporating the mixture with water to form wet concrete; and curing the wet concrete. During the curing step, the MIL-101(Cr) MOF adsorbs water to from a surrounding atmosphere. The MIL-101(Cr) MOF is 3-9 wt. % relative to the cement, such that water adsorption by the MIL-101(Cr) MOF enables the wet concrete to self-cure. The present disclosure also discloses a composition for forming concrete, the composition compromising cement, aggregate, water, and MIL-101(Cr) metal-organic framework (MOF), wherein the MIL-101(Cr) is 3-9 wt. % relative to the cement. The present disclosure also discloses a self-curing concrete.
