Towards improving the performance of transplanted porous bioceramics, numerous processing techniques are available for the control of porosity, pore size distribution and pore alignment. For crystalline materials, grain size and crystalline defects provide further pathways to enhance biodegradation and osseointegration, which are key for ...
Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
Porosity of subsurface soil is lower than in surface soil due to compaction by gravity. Porosity of 0.20 is considered normal for unsorted gravel size material at depths below the biomantle. Porosity in finer material below the aggregating influence of pedogenesis can be expected to approximate this value. Soil porosity is complex.
Micro CT of porous medium: Pores of the porous medium shown as purple color and impermeable porous matrix shown as green-yellow color. Pore structure is a common term employed to characterize the porosity, pore size, pore size distribution, and pore morphology (such as pore shape, surface roughness, and tortuosity of pore channels) of a porous medium.
A pervious concrete street in 2005. Pervious concrete (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge.
A concrete densifier is a chemical hardener that penetrates the concrete surface, reacting with the material to form crystals that fill the pores and increase surface density. This process significantly improves the concrete's resistance to wear, dusting, and chemical damage.
The concept of vascular healing in concrete utilizes a biomimetic approach to self-healing. The human cardiovascular system, which conducts blood throughout the body, and the plant vascular tissue system, which transports food, water, and minerals via xylem and phloem networks, are examples of vascular network systems. Similarly, vascular ...
Polished concrete may be considered a form of sustainable design flooring, if less material is used than in comparable types of flooring. [citation needed] Polished concrete floors have the following advantages: low-maintenance [7] – polished concrete is easily maintained with the use of clean water or a neutral pH cleaner. The application of ...
