Mortar specimens were exposed to either a 3% NaCl solution or NaCl+KOH for up 180 days. Exposure the provoked much more leaching than exposure. Leaching strongly impacted chloride ingress profiles. The extended led maximum total content almost three times higher and deeper penetration exposure with limited after seems be linked enhanced binding capacity of C-S-H AFm phases upon moderate as dete...

The market demand for manufactured sand has grown rapidly, and the solution to problem of optimum stone powder content from concrete is imminent. workability, early age shrinkage strain cracking, strength, chloride ion penetration, pore structures with different contents were tested study influence concrete. test results show that addition beneficial in improving working performance But at same...

This study aims to investigate the chloride diffusion behavior of alkali activated slag and fly ash blends with different contents waste glass powder (GP) addition. The reaction heat flow slag/fly ash/waste is characterized. products are determined by X-ray diffraction thermogravimetric analysis (TGA). N2 adsorption (BET) used evaluate microstructure samples. accelerated penetration test (ACPT)...

Unidirectional chloride ion jiuxes were measured in the cat ciliary body isolated as a living membrane in vitro. A statistically significant net chloride ion influx (nutrient to secretory) was demonstrated both in the presence of the spontaneous membrane potential and in short-circuited membranes. The isotopically measured net chloride ion influx exceeded the short-circuit current of the membra...

The present work is a study of the corrosion susceptibility of steel drums in contact with cemented ion-exchange resins contaminated with different types and concentrations of aggressive species. A special type of specimen was manufactured to simulate the cemented ion-exchange resins in the drum. The evolution of the corrosion potential and the corrosion rate of the steel, as well as the electr...

In this paper, three modified tetraethyl orthosilicate surface treatment agents were prepared by using (TEOS) as the preparation monomer, isobutyltriethoxysilane (IBTS) hybridizer, and acrylic acid, phosphoric hydrochloric acid catalysts. The effects of on permeability airport pavement concrete investigated water absorption tests, contact angle penetration resistance chloride ion carbonation me...

Considering a constant demand in construction of concrete structures to develop novel approaches for predicting the concert’s properties, host investigations were performed on concrete’s mechanical properties and durability under various curing regimes. However, few studies concerned with evaluating using non-destructive surface resistivity tests by applying conditions. The present study compar...

The present study aimed at assessing mechanical and durability characteristics of ground granulated blast furnace slag (GGBS)-based geopolymer composites 5%, 10%, 15%, 20%, 25%, 30% replacement proportion silica fume 12 molarity NaOH. Mechanical properties were assessed using compression tension tests, whereas evaluated ultrasonic pulse velocity test (UPV), acid test, rapid chloride permeabilit...

in this study, the effect of cement content on concrete performance in corrosive environments is investigated on concrete mixtures having the same water/cement (w/c) ratio. three w/c ratios (0.40, 0.45 and 0.50) were used and for each w/c ratio three mixtures were prepared with cement contents 350, 400 and 450 kg/m3. the compressive strength, electrical resistivity and chloride diffusivity of t...
