TL;DR: In this article, the authors investigated the carbon footprint of CCR and fly ash-based marine clay and found that CCR is an industrial byproduct obtained from acetylene gas production, high in Ca(OH)2 and was used as a green additive to improve strength of the FA based geopolymer binder.

TL;DR: Granulated Blast Furnace Slag, which is traditionally considered as a waste material, is used as a replacement and partially reactive material in FA geopolymer pavement applications, and microstructural analysis indicated the coexistence of Calcium Silicate Hydrate (CSH) and Sodium Alumino Silicates Hydrate products in FA geopolitical stabilized LS/GBFS blends.

TL;DR: In this paper, the authors investigated the feasibility of using CCR, a cementitious waste material, as an alkaline activator and fly ash (FA) as a precursor to improve the engineering properties of a problematic silty clay to facilitate its usage as stabilized subgrade material.

TL;DR: In this paper, the suitability of recycled construction and demolition materials as alternative pipe backfilling materials for stormwater and sewer pipes was investigated to assess their suitability as a pipe back-filling material.

TL;DR: In this article, a comprehensive suite of geotechnical laboratory tests was undertaken on samples of recycled crushed glass produced in Victoria, Australia and three types of recycled glass sources were tested being coarse, medium and fine sized glass.
