Durability of concrete containing synthetic zeolite from aluminum fluoride production waste as a supplementary cementitious material

• Zeolite from waste of AlF3 production was obtained by low-temperature synthesis.
• Concrete samples with zeolite admixture were produced.
• Properties of fresh mix and hardened concrete were tested.
• Durability was evaluated by capillary absorption and freeze/thaw test.

The article analysis the effect of synthetic zeolite on properties of concrete mix and hardened concrete. Zeolite was obtained from waste of aluminum fluoride production by low-temperature synthesis and added in concrete mix up to 10% as Portland cement replacing admixture. Test results revealed that, replacing cement by synthetic zeolite considerably decreases concrete scaling during freezing and thawing cycles. Compressive strength, density of concrete and water absorption were measured. The test results proved that synthetic zeolite obtained from aluminum fluoride by means of low temperature synthesis can be used as a supplementary cementitious material to increase the durability of concrete.
