Metallic aluminium in municipal solid waste incineration fly ash as a blowing agent for porous alkali-activated granules.

Porous alkali-activated materials are synthetic aluminosilicates that should be often produced as granules for practical applications. In the present study, municipal solid waste incineration fly ash with ~1.2 wt% of metallic aluminium was used as a novel blowing agent for metakaolin (their ratio ranged from 0% to 100%) with an aqueous sodium silicate solution as the alkali-activator and granulation fluid in high-shear granulation.

A review on sustainable use of agricultural straw and husk biomass ashes: Transitioning towards low carbon economy.

In order to mitigate the problems associated with the deposition of biomass ashes, it becomes essential to use these materials efficiently. One solution to the problem is utilization of these wastes in the concrete industry. Due to the massive development of infrastructure, the demand for cement is tremendously rising which results in the surge of cement concrete by 30 billion tonnes every year.

Turning waste expanded polystyrene into lightweight aggregate: Towards sustainable construction industry.

With the limited supply of energies that we can extract or mine from the earth, low energy consumption building is indeed a demand for the present situation with the use of sustainable building materials. Owing to the frequent use of EPS in the packaging industry, the versatile use of non-biodegradable EPS contributes to increasing global waste generation. In this regard, the utilization of recycled EPS in concrete production can be a sustainable approach to manage embodied energy.

Effects of carbon nanotubes on expanded glass and silica aerogel based lightweight concrete.

This study is aimed to investigate the effect of carbon nanotubes on the properties of lightweight aggregate concrete containing expanded glass and silica aerogel. Combinations of expanded glass (55%) and hydrophobic silica aerogel particles (45%) were used as lightweight aggregates. Carbon nanotubes were sonicated in the water with polycarboxylate superplasticizer by ultrasonication energy for 3 min.
