The permeability of concrete refers to its capacity to allow the passage of water and moisture. Permeability plays a crucial role in various aspects, including preserving the longevity and visual appeal of structures, as well as minimizing issues related to leakage and deterioration. Several methods have been devised to enhance the permeability of concrete, and one such method involves incorporating chemical crystals called Crystal-X. These materials improve the concrete's hydrophobic properties, reducing the likelihood of water leakage. Crystal-X possesses the capacity to absorb water that is found within the pores of the concrete and transform it into crystals that are not soluble. When the pores become saturated with these crystals, they create a barrier that prevents water and moisture from entering. The outcomes of multiple laboratory tests performed on both fresh and hardened concrete were elucidated and clarified subsequent to the incorporation of Crystal-X as an additive, at dosages ranging from 0.9% to 1.3% of the weight of the cement. The concrete's workability was assessed through a slump test, while its hardened state was evaluated through tests measuring compressive strength, permeability, and absorption rate. After a curing period of 28 days, the addition of Crystal-X at a rate of 1.3 % by weight of cement resulted in a 15.93% increase in the compressive strength of the concrete. Similarly, the permeability of the concrete decreased by 11.9% when Crystal-X was added at the same rate.
