Health Problems Caused by Living on Concrete Floors
Concrete floors have long been used in industrial buildings, and recently they have become popular in residential apartments and homes, too. But while concrete floors are in vogue, people who live on them can suffer from a number of health problems resulting from exposure to concrete and the lack of shock absorbency they provide.
Is cement a toxic substance?
The main threats are the alkaline calcium oxide and trace amounts of silica. During dumping, grinding, or pouring of the cement, toxic dust accumulates in the air. When you breathe this air, the calcium oxide is deposited on different body parts, such as the lungs. The oxide reacts with moisture to form the corrosive calcium hydroxide.

Is concrete made of fly ash?
Not all concrete blocks are made with fly ash. Most concrete is made by mixing Portland Cement with sand, aggregate stone. The mixture hardens when mixed with water through a process called “curing.” These types of blocks are generally considered safe and toxin free.
Can you use concrete blocks for a garden?
But are they safe? Are concrete blocks toxic to the environment, you and your plants.? The answer is yes and no. Concrete blocks , a.k.a cinder blocks, can be made with materials that could potentially cause health issues if consumed. Fly ash, which is a byproduct of burning coal and used to make some types of cinder blocks, can leach toxic substances like calcium oxide, aluminum oxide, and magnesium oxide into the soil. Other heavy metal byproducts such as lead and arsenic may also be present and could also leach. In addition, lime can leach into the soil which can raise pH levels over time.
What can contaminate the environment around the blocks?
Here is a list of the substances that can contaminate the environment around the blocks: Consuming or breathing in any number of these substances in unhealthy amounts can cause damage to the nervous system, heart, gastrointestinal system, lungs, and kidneys.
What are the toxic substances in fly ash?
Concrete blocks created with fly ash have been found to leach toxic substances into the soil. These include calcium oxide, aluminum oxide, and magnesium oxide. There are other heavy metal byproducts such as lead and arsenic. In addition, lime can leach into the soil over time, raising its pH level.
What is the difference between Portland cement and fly ash?
Blocks that are only made from Portland Cement are heavier and more expensive while those that are made from fly ash are cheaper and lighter in weight . If you are looking to buy cement blocks, it won’t hurt to ask the retailer if the blocks they sell contain fly ash.
What is the difference between cement and cinder blocks?
There’s a distinct difference between cement and cinder blocks. Most concrete is made by mixing in Portland Cement, a mixture that is manufactured in the UK. It contains many compounds that, when mixed with water through a process called “Hydration,” hardens over time. These are generally safe and toxin-free.
Why do people use concrete blocks?

There are many uses for fly ash. However, there have been many instances of negligence in which fly ash has contaminated groundwater. In addition, it can contaminate surface water as it erodes, through runoff, and even though particles that become airborne and land in the water.
Is fly ash a substitute for Portland cement?
It contains calcium sulfate, calcium-rich glass, and magnesium oxide. Class C fly ash can become cement when added to water, much like Portland Cement. This is why fly ash is currently used as a replacement or partial-replacement for Portland Cement in many concrete mixtures. It’s cheaper, and some claim that it actually improves the concrete.

What is the top layer of concrete?
The top layer of the concrete would be a thin layer of dye-sensitized solar cells. Dye-sensitized solar cells are particularly attractive due to its ease of mass production, either via roll-printing or painting, and a reasonably high efficiency of 10%.
Why is concrete recycling important?
Concrete recycling is increasing in response to improved environmental awareness, legislation, and economic considerations. Conversely, the use of concrete mitigates the use of alternative building materials such as wood, which is a natural form of carbon sequestering.
Why is concrete used in flood control?
Concrete is used to create hard surfaces which contribute to surface runoff that may cause soil erosion, water pollution and flooding. Conversely, concrete is one of the most powerful tools for proper flood control, by means of damming, diversion, and deflection of flood waters, mud flows, and the like.
How much CO2 does concrete cause?
