Zamzam Water as Corrosion Inhibitor for Steel Rebar in Rainwater and Simulated Acid Rain
Abstract—Corrosion inhibitors are widely used in concrete industry to reduce the corrosion rate of steel rebar which is present in contact with aggressive environments. The present work aims to using Zamzam water from well located within the Masjid al-Haram in Mecca, Saudi Arabia 20 m (66 ft) east of the Kaaba, the holiest place in Islam as corrosion inhibitor for steel in rain water and simula...
متن کاملActivity of earthworm in Latosol under simulated acid rain stress.
Acid rain is still an issue of environmental concerns. This study investigated the impacts of simulated acid rain (SAR) upon earthworm activity from the Latosol (acidic red soil). Laboratory experiment was performed by leaching the soil columns grown with earthworms (Eisenia fetida) at the SAR pH levels ranged from 2.0 to 6.5 over a 34-day period. Results showed that earthworms tended to escape...
متن کاملEffects of Simulated Sulfuric Acid Rain on Crop Plants
Since relatively little is known about the effects of acid precipitation on growth and productivity of crop plants, a crop survey was initiated to study effects of H 2SO 4 rain simulants on growth, yield, and quality of selected crops which were chosen to represent diverse taxo nomic groups and crop products. Yield responses of 28 crop cultivars were examined. Plants were grown in pots in field...
متن کاملCORROSION INHIBITION OF COPPER IN ACID MEDIUM BY DRUGS: EXPERIMENTAL AND THEORETICAL APPROACHES
The inhibition performances of nafcillin (III), methicillin (II) and penicillin G (I) on the corrosion of copper in HCl was studied and tested by weight loss, Tafel polarization, SEM, UV-vis spectrophotometry, molecular dynamics method and quantum chemical calculations. Polarization curves indicated that the studied inhibitors act as mixed-type inhibitors. The values of inhibition efficiency an...
متن کاملCorrosion and Inhibition Studies of Copper in Aqueous Solutions of Formic Acid and Acetic Acid
Corrosion behaviour of copper has been investigated in different compositions of formic acid and acetic acid at 30°C by a potentiostatic method. The maximum corrosion rate was found in 2&40mol/o formic acid and in 20 mol/o acetic acid in aqueous solution mixtures. The corrosion rate depended on the concentration of either acid. Formic acid is observed to be more corrosive than acetic acid. The ...
