Types and Causes of Concrete Deterioration
Carbonation-induced corrosion often occurs on building facades with shallow concrete cover. (70157) Carbonation of concrete also lowers the amount of chloride ions needed to promote corrosion. In new concrete with a pH of 12 to 13, about 7,000 to 8,000 ppm of chlorides are required to start corrosion of embedded steel.
Concrete Efflorescence
Efflorescence is caused by vapor migrating through the slab bringing soluble salts to the surface of the concrete. Efflorescence is normally worn off or washed away on unsealed concrete surfaces. In stubborn cases, a mild acid rinse or even a light sandblasting may be necessary.
How to Remove Asphalt From Concrete
A more abrasive way to remove asphalt from concrete involves the use of very strong chemicals to break down not just the stain but the top layer of concrete as well. This method can be used to not only clean concrete but also change the texture. Concrete etching solution usually includes some form of hydrochloric acid, which is extremely …
How To Break Up and Remove Concrete
There is also what's referred to as expanding grout—a chemical agent that helps break up concrete. A jackhammer may be required depending on site conditions; a rotary hammer for sure. Mix, pour, and wait. The grout expands and breaks the concrete. Plan ahead and consult the manufacturer's instructions for proper usage.
Everything You Need To Know Before Acid Staining A Concrete …
Plus, a tightly troweled concrete surface can be slippery in general. For already finished concrete, you should take stock of your surface finish before acid staining. Pour a little water on the patio and see how long it takes to soak in. This will give you an indication of how well the stain will soak in as well.
How to Acid Etch Concrete (with Pictures)
1. Mix water and acid in 3 or 4:1 ratio. Add clean, clear water to a plastic bucket. Very carefully pour your acid in, being sure not to cause any spills or splashes. Don't use a metal container — acid can corrode many metals, leading to the possible destruction of the container. Always pour acid into water.
How to Get Grease Stains Out of Concrete: Proven Methods …
Hydrochloric acid, commonly known as muriatic acid, is a powerful acid that can be used to remove grease and oil stains from concrete surfaces. Its strong acidic properties allow it to break down and dissolve the grease, making it easier to remove. However, caution should be exercised when using muriatic acid, as it can be harmful if …
Severe Sulfuric Acid Attack on Self-Compacting Concrete …
The so-called "constant sulfate method" refers to concrete immersed in an acid solution with initial pH of 2 (Figure 4). The High Research Council of Spain (CSIC) performed the test. Cylindrical cores were obtained, with a diameter of 75 mm from a 150 × 150 × 150 mm³ concrete cube. After eliminating the top and bottom external surfaces ...

3 Ways to Break Up Concrete
5. Chip the concrete near the cut. Use a heavy duty hammer drill or a breaking chisel attachment in a rotary hammer to chip the concrete next to the line you sawed. Tilt the chisel so the side you will be removing cracks loose, not the side you're keeping. [14] 6. Gradually deepen the hole.
How to Acid Stain Concrete
Step 8: Apply Acid Stain to Concrete. Use a pump sprayer to apply the acid stain. Apply enough to saturate the concrete but not to puddle. Apply in a zig-zag type motion to give it variation and a random look as opposed to applying in straight lines. (See the video for a better description).

Acid Attack | Concrete Experts International
What is Acid Attack? Concrete is susceptible to acid attack because of its alkaline nature. The components of the cement paste break down during contact with acids. Most pronounced is the dissolution of calcium hydroxide which occurs according to the following reaction: 2 HX + Ca (OH)2 -> CaX2 + 2 H2O . (X is the negative ion of the acid)
