Concrete durability, especially in water-logged environments might not be possible with conventional constituents of concrete. A combination of mineral and chemical admixtures in different proportions is used to study water absorption, sorptivity, and permeability behavior of concrete. The water absorption, sorptivity, and permeability test were carried out using nine (9) trial mixes of different proportions of Calcined Clay (CC), Sawdust Ash (SDA), Crystalline Based Admixture (CBA), and Superplasticizer (SP). The results showed that treating concrete with 5% CC + 5% SDA+1% CBA combination gives optimum performance in terms of sorptivity with reduced water absorption value of 4.60%. While the permeability coefficient of concrete is reduced when CC and SDA are added to concrete mix separately, the reactivity between their combination (CC and SDA) significantly increased permeability coefficient of the concrete. The study demonstrates that production of concrete with the right proportions of admixture and pozzolanas improve the durability of concrete structures.

Cement-based materials prepared with activated water induced by a magnetic field or electric field represent a possible solution to environmental issues caused by the worldwide utilization of chemical admixtures. In this contribution, electric- and magnetic-activated water have been produced. The workability and mechanical properties of cement mortar prepared with this activated water have been investigated. The results indicate that the pH and absorbance (Abs) values of the water varied as the electric and magnetic field changed, and their values increased significantly, exhibiting improved activity compared with that of the untreated water. In addition, activated water still retains activity within 30 min of the resting time. The fluidity of the cement paste prepared with electric-activated water was significantly larger than that of the untreated paste. However, the level of improvement differed with the worst performance resulting from cement paste prepared with alternating voltage activated water. In terms of mechanical properties, both compressive strength and flexural strength obtained its maximum values at 280 mT with two processing cycles. The compressive strength increased 26% as the curing time increased from 7 days to 28 days and flexural strength increased by 31%. In addition, through the introduction of magnetic-activated water into cement mortar, the mechanical strength can be maintained without losing its workability when the amount of cement is reduced.
