The amount and type of waste are increasing due to population growth. Many harmful materials have been in the atmosphere for a very long times. This causes a crisis in the waste disposal and thereby contributes to environmental issues. Recycling concrete manufacturing waste materials not only offers...

Permanent damages and spalling occur in conventional concrete due to high temperatures. Also concrete loses its compressive strength amounting to about 50 to 75% of the original strength as reported in most of the research works. As opting for high grade of concrete leads to higher costs and emits...

The microbial consortia incorporated in bio concrete should have traits such as high alkali resistance and the ability to form endospores to overcome the mechanical and chemical stresses produced during concrete preparation. The primary intent of our work is to segregate and identify the calcium...

Nanotechnology exemplifies advancement in the field of research and development by enhancing product efficacy through the introduction of novel solutions. In the field of cosmeceuticals, the use of nanotechnology is increasing to solve some of the limitations associated with conventional goods...

Nowadays, the increase in population and industrial growth that generates lot of waste products which creates disposal problems and severe environmental hazards. The cement industry is one of the important sectors which liberates greenhouse gas such as carbon dioxide. The consumption of waste...

This study investigates the effectiveness of fly ash-based geopolymer concrete was conducted to be used as an alternative material to replace the normal concrete. The concrete mixture was prepared by mixing fly ash, fine aggregate, nano-slag, and SP in Na2SiO3/NaOH solution. The mixture was divided...

The paper presents a laboratory study of concrete mixes based on the alkali-activation of an industrial by-product, ground granulated blast furnace slag (GGBS). A number of factors potentially affecting the resulting concrete quality in terms of workability and strengths were investigated (namely...

An experimental investigation was carried out to compare the compressive strength of zero slump and high slump concrete with high volume fly ash. 40% to 70% replacements of OPC (by weight) with class F fly ash have been incorporated. Superplasticizer was added at 1% of binder (cement + fly ash) to...

The present paper aims to assess the effect of various additives on the compressive strength of inorganic polymers (geopolymers) synthesised using low Ca electric arc ferronickel slag and alkali activating solutions. The main operating parameters include pre-curing (48 hours), temperature (40 to 80...

Stabilization/solidification (S/S) processes were utilized to immobilize lead (Pb) and tungsten (W) in contaminated soils, the inclusion of W motivated by the use of the new W-based ammunition. Artificially contaminated soils were prepared by mixing either kaolinite or montmorillonite with 10% Pb...

Discarded vehicle tyres constitute one important part of solid waste which had historically been disposed of into landfills. Recent EU policies on the Landfilling of Waste (Council Directive 1999/31/EC) have however put a ban on the landfilling of whole or shredded tyres, creating an imminent need...

The purpose of this study was to investigate the potential use of Para wood particle wastes and cement for producing the cement composite as a new environmental friendly construction material. Strength and durability of cement composites mixed with different mix proportions of Para wood particles...
