Description. IMPACTA Crete-Off is a nontoxic, biodegradable ,environmentally green liquid designed to dissolve the Portland cement component in concrete, mortar, thin set, grout, and other Portland cement products.
Sulphuric acid or hydrochloric acid. To dissolve concrete (cement), you can use: Hydrochloric acid (HCl) – Strong and fast, but dangerous. Sulfuric acid (H₂SO₄) – Very strong, eats through concrete, highly dangerous. Phosphoric acid (H₃PO₄) – Safer, slower, good for cleaning.
The Solution
Cretesol distributes a product that molecularly breaks down the ionic bond in cement and concrete. This groundbreaking solution is easy to apply and effortlessly eradicates hardened cement or concrete from any surface, transforming it into rinsable mud.
Knockout 100™ is the most powerful technology developed for the removal of concrete from Ready Mix trucks and other concrete equipment. Although it is safe on most common materials such as iron, steel, plastic, rubber and vinyl, Knockout 100 quickly eats through thicker accumulations of dried concrete.
It will dissolve the concrete because it is an acid, but it is such a mild acid with a pH of around 2.5, that it is unlikely to be very effective on anything but the lightest contamination, but under the right conditions could still damage your car clear-coat.
Zep Mudslide Concrete Dissolving Cleaner with Zep Model 50 Pump offers a safe and effective solution for removing concrete build-up from vehicles, tools, and job site equipment. The acid-free formula contains no hydrochloric, phosphoric, or sulfuric acids, making it safer for use on metal surfaces.
Will straight bleach harm concrete? Yes. Undiluted bleach can damage concrete by causing surface erosion, discoloration, and deterioration of sealers. It should never be applied full-strength on concrete surfaces.
Make your own dried concrete, slurry, cement, mortar, and grout remover for cleaning equipment and tools for about a $1.00 a gallon. Using citric acid, sugar, and baking powder. Simple, easy mild solution for cleaning your concrete off your tools.
This DIY guide focuses on using a sledgehammer to remove concrete, as it is the easiest and most affordable method to do it yourself.
The answer is yes, salt does indirectly damage your concrete driveways, patios and sidewalks. Bumps and potholes don't just appear due to regular wear and tear – salt damages concrete over time by causing corrosion to occur under the surface, leading to discolored, cracked and crumbling concrete.
This material is typically produced at a utility sluice pond site by dumping raw ash into the pond and allowing it to hydrate and harden into a working platform. Additional raw ash is placed on top of the platform in thin lifts, watered, compacted, and allowed to hydrate and harden.
How to Break Concrete
A good material proportion “rule of thumb” regarding concrete mixtures is the 10:20:30:40 mixture ratio which is about 10% cement, 20% air and water, 30% sand, and 40% stone based on the absolute volume of the concrete mixture.
EZ Grind is ideal for very hard concrete surfaces possibly caused by over-trowel and/ or due to any prior applications of silicate hardeners. This concrete chemical solution has been shown to reduce labor costs by 30%, with no smell or fumes. It can also be applied easily in a high-volume, low-pressure pump-up sprayer.
Easily remove concrete from your tools and equipment with Mean Klean 22 oz. Concrete & Mortar Dissolver. The advanced liquid formula dissolves and physically breaks down concrete by attacking the Portland cement, eventually reducing it to mush that is easy to clean off with a hose or pressure sprayer.
Baking soda is also known by its chemical name, sodium bicarbonate. Sodium bicarbonate acts as an accelerator in concrete, causing it to rapidly stiffen.
Compared to commercial "form oils", Castor Oil based release is a great alternative. Diesel motor oil, WD40 and other harsh chemicals are commonly used within the construction trades to repel the tack of concrete to forms and molds. One caveat, Castor Oil is a known laxative. Ingesting might create some potty time!
Cleaning concrete with vinegar or baking soda is a good option if you are looking for a natural cleaner. While cleaning concrete with bleach or detergent can be effective, it can also be toxic to plants.
Vinegar is a go-to product for most of the cleaning jobs including cement stain remover from the floor tiles and slabs. Mix one part of vinegar with one part of warm water brushing the solution onto the surface. Leave the solution to absorb and rinse with a soft brush and clean water.
Some contractors use at least a little degreaser for most jobs, even to remove dirt, which can be somewhat oily. According to Hinckley, alkaline cleaners are also the preferred chemical for cleaning soot from concrete. Heavy rust stains can penetrate deeply into concrete, so they can be tough to remove completely.
