Water reducer was used in order to maintain the water-cement ratio of 0.4, with dosage ranging between 3.0% and 3.2% mass of cementitious material.
It is suggested that etch hole of concrete will get more and more bigger due to Ca(CH3COO)2 which is soluble in water easily.
This is caused by the corrosion of hydration products containing calcium and forming soluble calcium acetate in water.

A 0.2-g powder of sample was extracted with 100.0 ml 70% ethanol in an ultrasonic water bath for 30 min.
The mobile phase consisted of acetonitrile(A) and 0.05% phosphoric acid in deionized water (B) using gradient program of 19% (A) and 81% (B) in 0—8min,19→50% (A) and 81→50 (B) in 8—35min, 50→100% (A) and 50→0%(B) in 35—36 min, 100→19%(A) and 0→81% (B) in 36—40 min.

The absorption of CO2 in water (H2O) results in the formation of carbonic acid (H2CO3).
These values are obtained directly from the software Reports suggest that the addition of CO2 to water reduces the pH of water used due to the formation of carbonic acid.

Bridge Scour is the localized loss of the geomaterials around the foundation of a bridge as a result of the movement of water around it.
Bridges are structures constructed over water bodies, valleys, and roads to allow for passage of vehicles, humans and goods across the span of the bridge.
Due to the scouring action of water, bridge failures occur [8].

In the same vein, [11] asserted that wood ash concrete absorbed more water with increase in wood ash content.
The concrete mix ratio used was 1:2:4 (Cement:FA:CA) with water-cement ratio of 0.5.
The specimens were covered with polythene and left for 24 hours; demoulded and put in a water curing tank.
However, addition of more water is detrimental to the strength property of concrete.

After that, demolding is carried out and then the test object is treated by immersing it in fresh water for the specified test period.
The HCP was determined utilizing a digital avometer (Avometer Digital Zotek ZT 112) and a reference electrode (Professional 112 Type Silver/Silver Chloride) composed of Ag/AgCl, which was linked to the specimen (Fig. 3).
