Describing a construction, material, or joint that does not utilize cement or a cement-based adhesive for binding or solidification. It implies an alternative method of joining or fixing components, often relying on mechanical means like fasteners, pressure, friction, or the inherent properties of the materials themselves. The absence of cement in such structures can provide advantages like flexibility, recyclability, and often simplifies construction and deconstruction processes. The approach can also be applied to implants and medical instruments.
Non-cemented meaning with examples
- Traditional dry-stone walling is a prime example of non-cemented construction. The stones are carefully arranged, relying on their weight and interlocking shapes for stability, without any mortar or cement. This method offers excellent drainage and environmental benefits, making it suitable for various outdoor constructions in many different climates. Such construction is a sustainable building technique.
- Modern prosthetic implants can be designed as non-cemented, with a porous surface that encourages bone growth and integration. This eliminates the potential complications associated with cement failure and enhances the long-term stability of the implant. This technique facilitates faster patient recovery.
- Certain specialized surgical instruments utilize a non-cemented design, where the components are precisely fitted together and secured by mechanical means. This allows for easy disassembly for cleaning and sterilization, which is crucial for minimizing the risk of infection during operations and post-operative treatment.
- In some forms of bridge construction, specific segments may utilize a non-cemented connection, such as a dry-joint system. This can provide a degree of flexibility to accommodate movement and thermal expansion, which is especially useful in seismically active areas, increasing the resilience of the infrastructure.
- Recycled composite decking materials can be fastened together using screws or interlocking systems, creating a non-cemented deck surface. This provides a durable and weather-resistant surface without the use of cement. This method is also more sustainable than traditional materials.
