Superplasticizers01:30

Superplasticizers

122
Superplasticizers are advanced admixtures that enhance the workability of concrete by lowering the water content without compromising the strength of the material. These substances are highly effective water reducers, improving concrete flow, making it easier to work with, and enabling concrete to reach inaccessible areas or densely reinforced sections without mechanical vibration. The key components in superplasticizers are either sulfonated melamine or naphthalene formaldehyde condensates,...

Bioremediation

20.1K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Environmental Applications of Microorganisms

268
Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Deleterious Substances in Aggregate01:25

Deleterious Substances in Aggregate

259
Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.
Another type of impurity is clay and fine material that...

Plasticizers01:31

Plasticizers

116
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Area of Science:

  • Geotechnical Engineering
  • Environmental Engineering
  • Materials Science

Background:

  • Red mud (RM) is a toxic industrial byproduct from aluminum processing, posing environmental risks due to storage and potential spills.
  • Stabilization of RM is crucial for its utilization as a geotechnical material, particularly in pavement applications.
  • Existing methods like cement and geopolymer stabilization have limitations regarding durability and environmental impact (carbon footprint).

Purpose of the Study:

  • To evaluate the influence of lime, fly ash (FA), and GGBS, individually and in combination, on the strength and durability of stabilized RM.
  • To assess the suitability of stabilized RM for pavement construction, specifically subbase and base courses, according to Indian Roads Congress (IRC) standards.

Main Methods:

  • Investigated the unconfined compressive strength (UCS) and durability of RM stabilized with varying percentages of lime, FA, and GGBS.
  • Compared the performance of different stabilization mixes, including individual and combined applications of additives.
  • Evaluated UCS at 7 and 28 days of curing and assessed durability aspects against established pavement engineering criteria.

Main Results:

  • Lime stabilization alone did not meet durability requirements, although it showed moderate strength gains.
  • Fly ash (FA) combined with lime improved UCS and durability up to 30% FA with 20% lime addition.
  • Lime-GGBS combinations demonstrated significant potential, achieving UCS values between 5.79 MPa-9.83 MPa and satisfying durability criteria, with a specific mix (RMGGBSL 503020) exceeding 8 MPa.

Conclusions:

  • Lime-GGBS stabilization offers a promising eco-friendly alternative for utilizing red mud in pavement construction, meeting strength and durability standards.
  • Stabilized RM, particularly with lime-GGBS, is suitable for subbase and base courses as per IRC:37-2018 guidelines.
  • Despite challenges with mixing finer RM, stabilized materials are viable for low-volume road construction.
