Assessment on slag based geopolymer concrete blended with industrial waste using different ratios of alkaline liquid to binder and NaOH/Na2SiO3

by Kavipriya S. Iniya M.G.P. Sasivarman B.

Ecology, environmental change and management

At recent days, the rapid rate of increase in population and industrial growth generates enormous volume of waste products that creates environmental and health hazards. The production of cement is one of the key factors in liberation of CO 2 gases in atmosphere . The utilization of waste products...

Performance Evaluation of Drying Shrinkage and Durability in Pavement Quality Concrete with Recycled Aggregate, GGBS and I-Crete

by Chittibabu B. Durga Rani K.

Solid Waste Management

The study examines replacement of natural aggregates (NA) with Recycled Aggregate (RA) in Pavement Quality Concrete (PQC) M40 grade (M1) with 25%, 50%, 75% and 100% RA replacing NA in M2, M3. , M4 and M5 mixes. The compressive strength decreases with higher RA, but all mixes reach the target...

Sustainable approach of utilization of limestone and treated construction wastes as aggregates in the production of high temperature resistant green concrete

by

Loganathan S et al. View all

Issue 4

Solid Waste Management

Natural gravel used as aggregates in the construction had a severe impact on the environment leading to scarcity in recent times. Furthermore, the resistance of such natural aggregates to crack at higher temperature zones was less. This paper investigates the above concerns on scarcity and meagre...

Transforming waste into sustainable building materials: Properties and environmental impacts of Geopolymer concrete with recycled concrete aggregates

by

Periyasamy L et al. View all

Issue 2

Solid Waste Management

Industrial by-products such as cementitious materials or aggregates have the potential to mitigate the adverse environmental effects associated with traditional cement manufacture. Geopolymer Concrete (GPC) is more eco-friendly than conventional concrete because it does not require cement. GPC with...

Microbial Technique to Treat Recycled Aggregates from Construction Waste for its Effective reutilization in Concrete

by

Jagan S et al. View all

Issue 10

Solid Waste Management

Excessive consumption of natural resources for concrete production results in the diminution of conventional resources, leading to the scarcity of construction materials. Perhaps, the dumping of construction wastes increases the municipal wastes ensuing in disposal problems. The dumped construction...

Discarded tyre rubber as concrete aggregate: a possible outlet for used tyres

by

Mavroulidou A. and Figueiredo J.

Issue 4

General

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...

Alternative fillers for use in slurry seal

by

Oikonomou N. and Eskioglou P.

Issue 2

General

Slurry seal is applied for low-cost paving and surface maintenance. The principal materials used to create slurry seal are aggregates, asphalt emulsion, water and fillers like Portland cement (mainly), lime and other materials. This paper presents the use of alternative fillers instead of expensive...
