1. 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,
wherein during the step of curing, the MIL-101(Cr) MOF adsorbs water from a surrounding atmosphere, and
wherein the MIL-101(Cr) MOF is 3-9 wt. % relative to the cement,
such that the adsorption of water by the MIL-101(Cr) MOF enables the wet concrete to self-cure,
wherein the water-to-cement ratio is between 0.4-0.6 by weight.
