Not much you can do if the concrete is already hard, but if you are talking about plastic concrete (still in its wet state), there's lots you can do to hurt/weaken it:
- If you had the wrong chemical admixtures
- Any addition of water at the job site will weaken the concrete
- Failture to properly cure the concrete

Will placing a magnet on concrete damage it?
I don't have an answer but we have several large magnets in the shop I work in. It would appear that when we lower the cranes down and place the magnets directly on the concrete floor it tends to weaken them. I have always heard that placing a car battery on concrete would weaken the battery . Does a magnet act in the same fashion?
Can concrete block get wet?
Yes, concrete blocks can get wet, as they are porous materials that can absorb moisture. While they can withstand exposure to water, prolonged saturation can weaken their structural integrity over time and lead to issues like mold or freeze-thaw damage. Proper sealing and drainage systems can help mitigate these risks in construction.
How much water to add to ready mix concrete?
The amount of water to add to ready mix concrete typically ranges from 5 to 7 gallons per cubic yard, depending on the specific mix and desired consistency. It's important to follow the manufacturer's recommendations and adjust based on environmental conditions and the intended use of the concrete. Over-watering can weaken the mix, while under-watering can lead to inadequate hydration. Always measure carefully to achieve the best results.
What type of concrete should you use when making a concrete bench?
The best concrete for making a concrete bench is Bench concrete.
Will concrete stick to wood?
Concrete can stick to wood, but the bond may not be very strong. If the wood is rough and clean, it can provide some grip, but moisture and movement in the wood can cause the bond to weaken over time. For better adhesion, it's recommended to use a bonding agent or to treat the wood surface. However, it's generally advisable to use appropriate materials designed for specific applications to ensure durability.
What is the effect of the salt contamination of aggregate in concrete?
It would weaken the concrete, so keep out the salt.
How does concrete interfere with wireless communication?
Concrete interferes with wireless communication by weakening the signal of the radio frequency. Concrete's ability to weaken or completely stop radio frequencies from travelling through it are what causes the interference.
Will placing a magnet on concrete damage it?

How does the freeze-thaw cycle impact the durability of concrete structures?
The freeze-thaw cycle can weaken concrete structures by causing water to expand and contract within the concrete, leading to cracks and deterioration over time.
How does rust affect the durability of concrete structures over time?
Rust can weaken the steel reinforcement inside concrete structures, leading to cracks and structural damage over time. This can compromise the durability and stability of the concrete structure.
How does salt water damage concrete?
Salt water can damage concrete by promoting the corrosion of the steel reinforcement within the concrete. When salt water penetrates the concrete, it reacts with the steel, causing it to rust and expand, which in turn causes the concrete to crack and weaken. Over time, this process can lead to degradation and structural failure of the concrete.
Heat treatment concrete reinforcing steel rod?
Most specifications recommend not heating (annealing) rebar because it can weaken it.
Can concrete be melted by lava?
It might be possible to melt concrete if lava in contact with it was hot enough. But it is more likely that concrete would decompose and become "crumbly" before it "melted" when heated.
What is the abstract noun for the word weaken?
The noun form of the verb to weaken is the gerund, weakening.The noun 'weakening' is an abstract noun as a word for a reduction in value of money or financial markets.The noun 'weakening' is a concrete noun as a word for a physical loss in strength.
What effect does alkaline soil have on concrete?
Alkaline soil can increase the risk of concrete degradation through a process known as alkali-silica reaction (ASR). This reaction occurs when alkaline substances from the soil react with the silica in the concrete aggregates, causing the concrete to develop cracks and weaken over time. It is important to consider the soil conditions when designing concrete structures to prevent potential damage from ASR.
What bugs eat concrete?
There aren't any bugs that eat concrete, but the insect called a termite can damage soft concrete. They do this by removing individual grains of sand. The result is, it looks like the termite has been eating the concrete.
What acid will dissolve concrete?
Hydrochloric acid (HCl) is commonly used to dissolve or weaken concrete due to its strong acidic properties. However, using such acids can be hazardous and should only be done with proper safety precautions and expertise.
