Aci 350 Water Tank Design Pdffactors Affecting Permeability Of Concrete

the effect of crystalline waterproofing admixtures on the,according to aci 212.3 r-16 [2,9,10], admixtures designed to reduce water penetration into concrete are classified into two subcategories: permeability-reducing admixture for non-hydrostatic conditions (pran), formerly referred to as a “moisture repellent admixture” where resistance to water under pressure is very limited and is not suitable for concrete exposed to water under pressure.design and performance of reinforced concrete water,the tank was designed to satisfy the serviceability and strength criteria in can/csa s806-12 (csa 2012), aci 440.1r-06 (aci 2006), and aci 350/350r-06. the tank is fully instrumented at critical.
