Abstract
An anti-radiation concrete comprising a geopolymer is described. In an implementation, the anti-radiation concrete comprises a mixture of at least two aqueous alkaline activators, fine aggregate, and coarse aggregate from high density metal-containing rocks.
Claims10
An anti-radiation concrete, comprising:
- a geopolymer;
- a mixture of at least two aqueous alkaline activators, wherein a weight ratio of the geopolymer to the at least two aqueous alkaline activators is 2:1 to 3:1;
- a fine aggregate comprising a sand and waste iron, wherein a weight ratio of the sand to the waste iron is 1:1 to 3:1;
- and
- a coarse aggregate of particles having a particle size of 4.5 millimeters to 8.0 millimeters and comprising hematite ore, dolomite ore, cassiterite ore, or any combination thereof.
