Summary
Cement burns are rarely reported but require specific management. Early surgical intervention, including debridement and skin grafting, improves outcomes and reduces socioeconomic costs for these industrial injuries.
Area of Science:
- Burns Management
- Occupational Health
- Trauma Surgery
Background:
- Cement burns are uncommon but present unique diagnostic and management challenges.
- Literature on cement burns is sparse, despite their potential for disability.
Purpose of the Study:
- To review cement burn admissions over a decade.
- To analyze patient demographics, injury characteristics, and treatment outcomes.
Main Methods:
- Retrospective review of 46 patients admitted with cement burns (1996-2005).
- Analysis of injury settings, affected body areas, and treatment modalities.
Main Results:
- Most burns occurred in industrial settings (87%) among adults (mean age 32).
- Extremities were universally affected (mean TBSA 6.5%), with a mean hospital stay of 21 days.
- 82% underwent surgical management (debridement and split-thickness skin grafting).
Conclusions:
- Increased awareness of cement burn prevention and treatment is needed.
- Early surgical intervention (debridement and skin grafting) is crucial.
- Timely treatment reduces socioeconomic impact and facilitates return to work.

01:22Burn Injuries
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

01:26Flail Chest-II
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

01:21Types of Cement I
Portland cement comes in several types, each with distinct properties and applications based on their chemical composition and hydration characteristics:
Type I (Ordinary Portland Cement) is widely used for general construction where special properties are not required. It has moderate sulfate resistance and heat of hydration.
Type II (Modified Cement) offers moderate resistance to sulfate attack and a lower rate of heat development compared to Type I. It is suitable for structures in...

01:29Strength and Heat of Hydration
The hydration of cement is an exothermic reaction in which heat is generated as cement hydrates. This heat of hydration is critical to cement's strength development. The rate at which this heat is generated affects the temperature rise, with a majority of the heat being released early in the hydration process, half within the first three days, and about 75% within the first week.
The heat of hydration for each cement compound is significant; for instance, tricalcium aluminate (C3A) and...

01:24Hydration of Cement
Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...
01:21Portland Cement
Portland cement is the essential binding ingredient in concrete, made from finely ground materials including lime, iron, silica, and alumina. Lime is derived primarily from limestone, marble, marl, seashells, and clays, which also supply iron and alumina, while silica is sourced from sand, chalk, and bauxite. Contemporary manufacturing of Portland cement is a significant source of carbon dioxide emissions, prompting research into reducing its content in concrete through alternative...
