GK Topic, Water proofing material using flyash
Fly ash is extremely water-loving (hydrophilic), it turns into a highly water-repelling surface once coated with stearic acid. The head of stearic acid which is hydrophilic binds to fly ash particles, the water-repelling tail remains free. Numerous free hydrophobic tails of stearic acid makes the fly ash surface water repellent.
