“…1, concerning the zirconium concentration increase phenomenon indicated that the cations exchange in the intercalation process had been occurred. In this matter the writer agrees with Plamondon [6], which stated that the intercalation was strongly influenced by cationic and non-ionic surfactant supported by polypropylene glycol (PPG). Although in this study the maximum intercalated Zr on bentonite was only 40% (Fig.…”

“…Owing to that cation exchange process, more than 95% intercalant cations would replace in the interlayer of bentonite [1,5]. Even some anions such as chloride and nitrate would follow intercalant cations entering into the interlayer of bentonite [6][7].…”

“…Modification of natural bentonite with a surfactant is an easy method to change the nature of the bentonite surface hydrophilic to hydrophobic [9][10][11]. The negative charge on the surface of the silica layer of bentonite can be attached to the polar compounds and cations in the interlayer of bentonite can be exchanged with organic cations [11][12][13][14].…”

“…PCEs superplasticizers are known to intercalate the clay structure easily by the PEO side chains (Lei and Plank, 2012;Ouellet-Plamondon et al, 2014). Novel PCEs with hydroxyl alkyl lateral chains enhanced the dispersion in cement in the presence of montmorillonite clay (Lei and Plank, 2012); thus, a lower amount of superplasticizer can be used to lower the yield stress in the fresh state, thereby improving the environmental balance.…”

Construction using earth is gaining interest in developed countries, whereas this practice is common in Africa and was more common in Europe 200 years ago. The forecasted increasing demand for cement in emerging countries has created the need for alternative building materials. In this study, recent cement and concrete technologies are transferred to earthen constructions to create a SelfCompacted Clay Concrete. We showed that the use of a superplasticizer (SP) with earth alone reduced the yield stress and was more efficient when cement was added. The optimal rheology was reached with 1% polycarboxylate ethers superplastizer and 5% calcium sulfoaluminate cement. The setting was studied with a digital penetrometer. The accelerated phase of the CSA hydration occurred within 6 hours only when 5% of CSA was in the earth mixture. Cement transformed the interstitial liquid water between particles into chemically bound water that did not affect the flow in the fresh state. Mechanical tests on the dried self-compacting-clay concrete showed that the compressive strength was increased by a factor of four when reducing the initial water content. The compressive strength of earth material is known to vary with the dry density and the clay content in the compressed earth block. The novelty of our approach is that the identical results can be achieved with a material poured in a formwork rather than compacted. Finally, the carbon footprint of the solution was evaluated, and the results show that this new material is competitive with current construction techniques.
