“…It can also be seen that the higher the chemical content in the block the better the compressive strength of the compressed earth blocks. This is consistent with the results of previous studies [13,[29][30] with cement as stabiliser in soil blocks. The test result of One-Way RM ANOVA (p-value = 0.001) for all chemical contents between the stabilised and unsatbilised blocks suggests that there is significant difference in the compressive strength test on the 28-day curing.…”

“…It can also be observed that the higher liquid chemical content (1.5%) achieved the higher strength as was also observed in the compressive strength test result in Figure 3. Studies by Bahar et al [27], Millogo & Morel [29] and Medjo Eko et al [30] with cement as stabiliser in soil blocks recorded similar trend. The recorded p-values of 0.088 and 0.123 for 1 -1.5% and 0.5 -1% respectively for chemical inclusion shows that there was no significant difference, but the p-value of 0.026 recorded for 0.5 -1.5 indicates a statistical significant difference at 28-day curing age.…”

Soil blocks are usually stabilised with cementing materials, fibres or chemicals to improve their performance properties for construction purpose. This study investigates the properties of compressed earth blocks stabilised with a liquid chemical (Pidiproof LW+). Experiment was conducted using 0.5, 1 and 1.5% weight contents of Pidiproof LW+ to produce compressed earth blocks and cured at 7, 14, 21 and 28 days. The blocks were tested for density, absorption coefficient, compressive strength and splitting tensile strength. It was found that with the exception of density test, the chemical inclusion in the other tests significantly improved the performance properties of the compressed earth blocks. Furthermore, the higher chemical content (1.5%) inclusion in the compressed earth block provided better performance properties. The paper concludes that the inclusion of the liquid chemical in the compressed earth blocks generally improved the performance properties of the blocks. Recommendation is made to the use of other chemicals for applicability in earthen construction.

“…The formation of these carbonates is linked to the biophysical-chemical conditions of the earth. Whereas, the calcite is the product of the carbonation of lime, once mixed with water and sand, it has the property of rapidly setting by agglomerating inert particles, such as quartz [7,8,3,9]. We found bands of humic and fulvic acids that are linked to any root activity at (2516.1, 2876.3, 530.5) cm -1 .…”

“…Figure 12 shows that the compressive strength of the earth F increases according to the cement content rate. All recent studies [9,3,6,10,11,12,13,21,22] have shown that the mechanical properties increase with the cement dosage without giving the function of this increase. Since this increase is varied according to the particle size and the mineralogical composition of the earth, which impacts the economic investment in cement.…”

Durability of the earth mortar: Physico-chemical and mineralogical characterization for the reduction of the capillary rise

Abstract. The stabilization of the earth material in the fields related to the earthen construction, in compliance with the standards in force, allows strong results of strength and durability. The chemical and mineralogical elements play an important role, in the presence of an 'optimum' cement dosage, to strengthen the ties between the clays and the grains of the earth.. This approach targets the search for better performances in the use of natural materials resource in an ecoresponsible habitat. This study presents the experimental results of the four techniques of mineralogical and chemical analysis on mortar specimens obtained from earth of the city of Fez. The results of the uni-axial compressive tests of the cylindrical specimens for this earth, associated by various percentages 0%, 4%, 7% and 10% by weight of cement, make it possible to analyze the effect of the mineralogical and chemical elements on the mechanical properties, namely Young's modulus, compressive strength and limiting deformation. However, we determine the water absorption coefficient of the mortar for different cement dosages in order to optimize the durability of the mortar against bad weather, rain and / or very wet climates. In the earth mortar of Fez, the strong presence of calcite (CaCO3), quartz SiO2 and dolomite CaMg (CO3)2 amplifies the improvement of the behavior of the material by the addition of cement. In fact, this strong presence of calcite stabilized the clay by cementing quartz and the cement matrix to strengthen the ties between the grains of the earth. In addition, with respect to the capillary rise, the water absorption decreases with the addition of cement. We also note that the evolution of the mechanical properties is of no importance except in the interval [4 to 7%] which represents the zone of effect for cement stabilization and which houses the optimum technicoeconomic cement dosing.Résumé. La stabilisation du matériau terre crue dans les domaines liés à la construction en terre, dans le respect des normes en vigueur, permet des résultats de résistance mécanique et de durabilité forts probants. Les éléments chimiques et minéralogiques y jouent un rôle déterminant et permettent, en présence d'un dosage 'optimal' du ciment, de renforcer les liens entre les argiles et les grains de la terre. Ainsi, la connaissance de la nature de la terre crue à utiliser dans la construction, par l'identification scientifique de ses composantes, est incontournable à cet effet. Cette démarche cible la recherche de performances meilleures dans l'utilisation des matériaux naturels et bio ressourcés au niveau d'un habitat éco responsable. Notre recherche présente les résultats expérimentaux des quatre techniques des analyses minéralogiques et chimiques sur des éprouvettes de mortier obtenues à partir d'une terre de la ville de Fès par la diffraction des rayons X, l'Infrarouge, le Microscope électronique à balayage et la fluorescence X. Les résultats des essais de compression uni-axiale des éprouvettes cylindriques de cette terre associé...
