Sulfuric acid is particularly aggressive to concrete because the calcium sulfate formed from the acid reaction will also deteriorate concrete via sulfate attack (Fig. 7). Fig. 7. Bacteria in sewage systems can produce sulfuric acid, which aggressively attacks concrete . In addition to individual organic and mineral acids which may attack concrete, acid-containing or acid-producing substances

Formic acid is the simplest carboxylic acid. Formate is an intermediate in normal metabolism. It takes part in the metabolism of one-carbon compounds and its carbon may appear in methyl groups undergoing transmethylation.It is eventually oxidized to carbon dioxide. Formate is typically produced as a byproduct in the production of acetate.It is responsible for both metabolic acidosis and

One common method of staining concrete is through the use of acid. Similar to concrete pigments, the range colors is typically confined to non-bright, relatively subtle tones. Water-based (acrylic) staining provides for a much larger number of colors, including black and white. Stains can be applied to concrete of any age, though the colors are typically more vibrant if the stain is applied
ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates. These ingredients are mixed with water to create concrete which is used as a primary construction material in buildings

Before breaking out the dye, I went around all the edges and taped them off with blue painter's tape to prevent it from getting on our baseboards, doors, or the remaining concrete floors. Once that was done, we opened up the dye and mixed it with a painter's stick over the concrete floor. Dye is much thinner than paint, so it's very easy to accidentally fling droplets across the floor

Concrete pH Testing problems and Solutions Once pH testing is done and you have high readings there seems to be a lot of different opinions on what needs to be done. The pH of new concrete will be approximately 12 to 13 mostly due to calcium hydroxide, which is a normally by-product of cement hydration. As a concrete surface reacts with carbon dioxide in air, the pH of the surface gradually is

Concrete is a composite material which is made up of a filler and a binder. The binder (cement paste) glues the filler together to form a synthetic conglomerate. The constituents used for the binder are cement and water, while the filler can be fine or coarse aggregate. The role of these constituents will be discussed in this section. Cement, as it is commonly known, is a mixture of
Acid stains are a reactive coloring process that penetrates into the porous concrete surface. This is probably the most permanent of all coloring options but is usually limited to eight colors. Now, these colors can be blended, diluted, streaked and tweaked to create many coloring options. The acid stains will chemically react differently to each piece of concrete by evidence of final color
The concrete needs to be easily removed from the forms. Pipe insulation from a hardware store was used for lab trials. This foam-like material was easy to work with and is reusable with the addition of tape. The bottom of the forms can be taped, corked, set on glass plates, etc. Small plastic weighing trays or Dairy Queen banana split dishes can be used as forms for boats or canoes. If
The acid will break down the concrete so it can be removed. Use the scrub brush to remove the broken down concrete. Once you're no longer making progress, repeat steps 3 and 4. You may need to apply the acid several times to remove the concrete completely. When you're satisfied with the results, rinse the paver with clean water. Be aware that the acid runoff will kill any vegetation in its
I have heard a bit of acid like vinegar can help take the alkali down but not too much as it will weaken the concrete. Eventually it will leach out when constantly refilling with water. The birds that drink from the sidewalk are fine. A sealer may give a temporary seal but I bet it would not last indefinitely as even pools need to be re-surfaced/painted. If you can testing with PH strips will
