Greening stabilized rammed earth: devising more sustainable dosages based on strength controlling equations

Weathering’s beneficial effect on waste-stabilised rammed earth: a chemical and microstructural investigation

“…FA was used together with an activator: cement in one case and CCR in the other. Quantities of FA for each mix were determined according to previous works in order to optimise their pozzolanic potential [6,27], considering that a quantity higher than 25% led to compaction difficulties [6]. Traditional RE (ELS) was prepared as reference.…”

“…The most used stabilisers are cement and lime but the need to reduce the environmental impacts in the building sector demands the use of more sustainable stabilisers (e.g. waste materials, biopolymers and geopolymers [5][6][7][8][9][10][11][12][13]). …”

On the Durability and Strength of Compacted Coal Fly Ash-Carbide Lime Blends

“…Nevertheless, there are many factors that are able to interfere in the pozzolanic reactions originated in the mixture and compaction of these residues and, consequently, influence their mechanical properties. Thereby, it is necessary to assess variables for the main parameters which govern the development of these reactions, such as: amount of lime, porosity, curing period and temperature, and correlate these with the mechanical response of the FA-lime blends (Haque et al, 2014;Rocha et al, 2014;Dash & Hussain, 2015;Islam et al, 2015;Saldanha & Consoli, 2016).…”

Textile-reinforced rammed earth: Experimental characterisation of flexural strength and thoughness

“…However, the use of these traditional 5 construction techniques became sparse with the development of concrete and steel materials, 6 which allowed for the production of buildings with lower workforce requirements. As a result, 7 in comparison with other construction technologies, research on earthen construction has 8…”

“…Schroeder [4] analysed the drying process of earthen elements and concluded that there is a relationship between the initial moisture, the drying process and the final strength of rammed earth walls. Additionally, research was carried out by Ciancio et al [5], Jiménez et al [6] and Da Rocha et al [7] on determining the dosage and specifications of the solid component materials (clay, silt, sand, gravel) and the expected properties of the mixed material before it was used to achieve the maximum density, compressive strength or erosion strength. A few studies have focused on the durability of earthen constructions and potential alternatives to enhance the lifespan of earthen constructions.…”
