Ordinary Portland Cement (OPC) is highly alkaline in nature with pH values above 12. When the cement paste comes into contact with the acids its components break down, this phenomenon is known as acid attack. If pH decreases to values lower than stability limits of cement hydrates, then the corresponding hydrate loses calcium and decomposes to amorphous hydrogel.
Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement.

rinsable mud. Kelly's Concrete Dissolve actually breaks down the iconic bond in Portland cement, releasing the cement from any surface to which it has adhered. Chemically speaking, it essentially converts the positive ions in the hardened matrix into negative ions and then dissolves the cement into a mud that can easily be rinsed away ...
Sep 25, 2015· Additionally, as concrete is damaged and breaks down, it becomes even more susceptible to these problems with chemicals and salt. To avoid these issues, your first step is proper installation of the concrete.
