Adverse health effects from cement generally result from exposure to skin or eye, or inhalation or ingestion of cement dust. Skin Contact – getting cement dust or wet concrete on your skin can cause burns, rashes, and skin irritations, (dermatitis).
According to experts, concrete floor systems can cause everything from bunions and ingrown toenails to shin splints, lumbar strain, and achilles tendonitis. It can also lead to lower back pain, stress fractures, knee pain, and worsening of arthritis symptoms.
In another study in Germany, the authors described six cases where corpses were encased in concrete and/or bricks. The results of these cases also showed slowed decomposition compared to non-sheathed cases, and therefore difficulties in an uncritical estimate of PMI.
Skin contact with wet cement that is not washed off immediately can cause inflammation of the skin, referred to as dermatitis, with symptoms that might include itching, redness, swelling, blisters, scaling or other changes to the skin. Cement burns may result in blisters, dead or hardened skin, or black or green skin.
Concrete causes damage to the most fertile layer of the earth, the topsoil. Concrete is used to create hard surfaces which contribute to surface runoff that may cause soil erosion, water pollution and flooding.
Exposure to cement or concrete dust can cause nose and throat irritation. Cement dust has been shown to contribute to lung function impairment, chronic obstructive lung diseases, pneumoconiosis, and cancer of the lungs, stomach, and colon.
However, since concrete or asphalt is the hardest, these surfaces create the maximum force. This force can significantly impact bones, tendons, and joints and may increase the chances of injury. Knee pain, for instance, is a common side effect of long-distance running.
But know this: While there is no convincing evidence directly connecting the unforgiving nature of concrete and musculoskeletal (MSK) injury, there may be some parallel connections. “Jobs that involve a lot of time on concrete may also require a lot of physical and emotional hard work,” says Dr. Payton.
In short, the difference between cement vs concrete is easy to clear once we know all the basics of their compositions. Cement is a binding agent made from limestone and clay; whereas concrete is a building material created through the proper mixing of cement, water, sand, and rock.
The extraction of raw materials for concrete production results in habitat loss and a decline in biodiversity. Concrete surfaces in urban areas absorb and retain heat, leading to elevated temperatures and exacerbating the effects of climate change.
Flush the Area With Water & Concrete Burn Neutralizer for 20 Minutes. Continually rinse the potentially exposed skin with cold running water for 20 minutes. Adding vinegar or another mildly acidic substance to the water can neutralize the alkalinity and stop the chemical damage from worsening.
Concrete can be highly caustic, resulting in ailments ranging from moderate irritation to the thickening and cracking of the skin or worse, and are associated with long healing times.
Our literature review found that concrete rubble has the potential to release some chemicals at levels that are above the state's water quality standards. However, the release of contaminants is dependent on several factors (such as pH, particle size, and age of the concrete).
Standing or walking on concrete flooring every day can result in backaches, knee pain, swollen legs and sore feet. Left untreated, you may experience injuries and chronic pain. Poor posture is a major cause of back pain. The rigidity of the floor causes increased pressure on your spine when you are walking or standing.
Mortar can also contain respirable crystalline silica (RCS). RCS is also found in concrete and can lead to the development of silicosis or scarring of the lungs, which results in a loss of lung function and severe shortness of breath. Exposure to high concentrations can lead to death.
If you pour a new layer over concrete right on top of the old one, you won't get proper adhesion. You must properly prepare your concrete slab and then apply a chemical bonding agent on top of it so your new concrete adheres properly.
Bottom line: Cement is a powdered ingredient used to make concrete. Concrete is the material used to make sidewalks, driveways and buildings. Sakrete makes a number of different concrete formulations in varying strengths and set times to meet the needs of different job requirements.
Curing can therefore be achieved either through maintaining mixing water in the concrete during early hardening or by preventing moisture loss from the surface by sealing. The ultimate choice of the particular method to use will take into consideration factors such as economy, esthetics, member shape, etc.
Hazard: Exposure to cement dust can irritate eyes, nose, throat and the upper respiratory system. Skin contact may result in moderate irritation to thickening/cracking of skin to severe skin damage from chemical burns. Silica exposure can lead to lung injuries including silicosis and lung cancer.
Embedding a body in concrete does not, however, prevent putrefaction and so odor is often detectable, although wrapping in cling wrap or in plastic bags may slow this process.
Cons: Concrete is the least forgiving of running surfaces, according to Timothy Noakes, author of “Lore of Running.” When running on concrete, the ground doesn't absorb any of the shock that travels through a runner's feet, knees, hips and lower back. This can lead to an increased injury risk.
Generally, knee injuries suffered on concrete involve some kind of blunt force with direct contact of the knee with the concrete. These injuries can result in: Patella, or knee cap, fractures: can occur when the knee is bent at 90 degrees, forcing the knee cap to absorb the full force of your body weight.
