5.1.1.1 The use of superplasticizers. The agro waste based geopolymer concrete's workability behavior can be enhanced by using superplasticizers, which are chemical additives that can reduce the viscosity of the mix and increase its flowability. This can improve the workability and make it easier to place and compact the concrete [ 129 ].

The cement production process contributes significantly to climate change by releasing continuous carbon dioxide emissions, a potent greenhouse gas. This study focuses on replacing cement in concrete with three alternative materials: eggshell powder (ESP), red mud (RM), and Construction and Demolition (C&D) waste. Thorough material …
Concrete is the most used construction material in the world. Consequently, the mass extraction of materials required for concrete production …
The analysis of the effects of using PET waste in the production of composite concrete using fractional PET waste substitutions of 5%, 10%, and 20%. The degree of permeability was observed to expand well with inclusion of polymers. The samples with 20% of PET absorbed more water than the ones without any polymer replacement .
Waste concrete has mainly been used for producing recycled aggregates; however, its full recycling is still not practiced. Alternative uses include applications as …
State of the art of lightweight concrete with waste materials In the new context of sustainable ecological development, using less cement for producing concrete is an important aspect and replacing it with eco-friendly materials should be a priority. Judging by the current needs regarding the environment protection, the concrete should be less ...
In addition to reclaimed glass a variety of other waste materials including mine tailings, waste foundry sand, ocean bottom dredgings and garbage frit have been incorporated into experimental pressed concrete brick in a process that is now available for commercial use. Many other materials have also been tested for possible use in this …

Research into the potential use of RP in new concretes and mortars has considered two opportunities as cement replacement: either as supplementary cementitious materials (SCMs), or as an inert material (filler) (Evangelista and de Brito, 2014). Regulation for both applications is generally based on performance, so this is the key point to focus ...

An additional advantage of inorganic WC used in concrete is that no other special processing is required when used as an aggregate. WC is a non-bio-degradable material, this waste affects human health and creates environmental nuisance, we can prevent this by using it concrete production (Awoyera et al., 2016).
Green concrete is a concept of integrating environmental considerations in concrete design and construction. It considers source depletion of raw materials, concrete mix design, structural design, construction, and maintenance of concrete structures (Prusty et al., 2016).Green concrete encourages sustainable and innovative use of waste …

Hence, an AC of 1.00 refers to a perfectly absorbing material, while a value of AC of 0.00 indicates that the material is completely reflective. Common values of AC for conventional concrete range between 0.03 and 0.05, a figure that increases to 0.10–1.00 in the case of PC [56]. This coefficient also depends on the frequency of the sound ...
