Waterproofing and Anti-Bacterial Admixtures in Concrete01:22

Waterproofing and Anti-Bacterial Admixtures in Concrete

111
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.
Waterproofing admixtures render concrete hydrophobic,...

Air-entraining Agents01:27

Air-entraining Agents

102
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Area of Science:

  • Materials Science
  • Chemical Engineering
  • Colloid and Surface Chemistry

Background:

  • Conventional foam drainage technology faces challenges in application due to difficulties in defoaming.
  • There is a need for advanced materials that offer controlled foam stability for industrial processes.

Purpose of the Study:

  • To design and synthesize a novel temperature-responsive surfactant for intelligent foam control.
  • To investigate the temperature-dependent behavior of the synthesized surfactant for foam drainage applications.

Main Methods:

  • Synthesis of a temperature-responsive surfactant using polyoxyethylene alkyl ether carboxylic acid, diethanolamine, and sodium chloroacetate.
  • Characterization of the surfactant's conformational transformation and self-assembly behavior across a temperature range of 20 °C to 120 °C.
  • Evaluation of foam stability and defoaming performance under varying temperature conditions.

Main Results:

  • The synthesized surfactant exhibits conformational changes with temperature, altering foam stability.
  • Foam rapidly bursts at low temperatures and is highly stable at high temperatures.
  • The foaming agent demonstrated stable performance over four temperature cycles, achieving a 90% temperature-controlled defoaming rate.

Conclusions:

  • The developed surfactant provides intelligent "high-temperature defoaming, low-temperature defoaming" capabilities.
  • The simple, low-cost, and eco-friendly preparation process facilitates potential industrial scale-up.
  • This technology is expected to advance foam drainage in gas fields, reducing costs and improving efficiency.
