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...

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...

High strength geopolymers were produced from coal combustion fly ashes. These matrices reached compressive strength values over 100 MPa, much stronger and denser than obtained by using Portland Cement binders. Size fractions were obtained by size separation techniques and the relationship between...

As an important resource for the IT sector and due to the extremely hazardous elements it contains and the low recycling rate, e-plastic waste management and recycling are growing swiftly. E-plastic waste utilization reduces aggregate costs, landfill costs and energy prices. Rapid population growth...

In this study, an attempt is made to understand the effectiveness on initial treatment of coconut shell on the strength of concrete. The coconut shell materials obtained from the agricultural wastes are used as a replacement for coarse aggregate in conventional concrete. From the particle size...

Numerous alternative fuels such as biodiesel as well as alcohols have been commercialized in both the industrial and transportation sectors. Cottonseed oil and propanol piqued our curiosity in this context. Many researches has been conducted on a single cylinder four strokes diesel engine competent...

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...

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...

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...

The primary goal of the research was to determine how recycled plastic fiber's shape affected the functionality of mortar made from naturally occurring limestone residue. The identical length (20 ± 2 mm) and diameter (0.45 ± 0.07 mm) of two types of recycled fibers, straight and crimped, were...

This paper deals with the geopolymerization of the red mud generated in the primary aluminium production and the slag generated in the ferronickel production, in order to develop inorganic polymeric materials with advanced mechanical and physical properties. In particular, the effect of the main...

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...
