“…Unstabilised rammed-earth is still the goal of scientific research for two main reasons. First, the heritage of rammed-earth buildings in Europe and the world is still important (Bui et al [3], Fodde [12]). The maintenance of this heritage needs scientific knowledge on the material to have appropriate solutions.…”

Earthen materials in general and rammed-earth in particular are ancient materials used for construction since time immemorial. Some earthen structures built centuries ago are still performing satisfactorily. However, in a lot of cases, the problem of durability still raises questions, since earthen material is very sensitive to water and since the maintenance is not always well done. This paper presents a study on the influence of water on the mechanical characteristics (compressive strength, Young modulus and Poisson ratio) of rammed-earth material. Experiments on suction were also carried out to study the relationship between suction and mechanical characteristics of rammed-earth. The results show that for low water contents: which are from the dry state (in the atmospheric conditions) to 4wt.%, the mechanical properties are constant. Explanations of this result are presented in relation to the capillary force between particles at the microscopic level of the material.

“…Earthen architectural sites are relics left over from production, culture, religion, and military activities in human history [1]. After hundreds of years of erosion, they have become increasingly precious because of their important historical positivism and nonrenewability [2][3][4][5]. However, in the arid areas of Northwest China, most earthen sites are exposed to adverse environmental factors for long periods of time, which results in cracking, collapse, erosion, and other damages.…”

Shrinkage differentiation and the need for multiple replenishments of slurry after fissure reinforcement are key problems for the grouting reinforcement of fissures in earthen sites. In this study, quicklime was mixed with 1.5% SH binder, clay, and fly ash in different proportions to prepare nine different mixtures and water-cement ratios of SH-(CaO + C + F) slurry. An expansibility test was performed, and based on the results, four groups of slurry were selected for a fluidity test. Ultimately, three different water-cement ratios were considered, and the mixing ratio of 3 : 2 : 5 was determined to produce the optimum slurry. The curing age was optimized according to the intensity and tensile and flexural strengths of the concretion. The selected slurry and curing age were then applied to testing traditional grouting technology and optimized grouting technology (i.e., microlime piles in the fissure) in fissure grouting field experiments. The acoustic wave, penetration resistance, and infrared thermal imaging results after fissure grouting were used to develop a preliminary explanation for the related mechanisms of slurry swelling, hardening, and lime pile compaction. The results showed that the combination of the preferred slurry and optimized grouting technology help address the problems of shrinkage differentiation on both sides of the fissure and need for multiple replenishments of the slurry after grouting.

“…The earthen architecture archaeological sites are the architectural remains of the earthen architecture built by ancient people despite hundreds of years of erosion [1][2][3][4][5] and represent the historical and cultural styles and architectural technique level during that period, and therefore they are having significant scientific and cultural value [6]. But, unfortunately, due to lack in preservation, most sites have been permanently damaged, and most of the existing sites are also in the state of danger and urgently require preservation [7][8][9][10].…”

This paper takes the preservation works on the archaeological sites of Gaochang Ruins, Xinjiang, as background. Based on the soil characteristics analysis on the archaeological sites, experimental studies were conducted on the consolidation effect of the BS-10 consolidation material on the archaeological sites of adobe and rammed earth. The results showed the following:, after consolidation, the wind erosion resistance of the soil on the archaeological sites was substantially increased, and the wind erosion modulus was reduced by 5~8 times; the soil exhibited fine grid structure and significantly reduced degree of permeability, while still maintaining the moisture exchange between inside and outside the soil; there is excellent ageing resistance; the resistance to freezing and thawing was closely related to the soil water content and had little influence in arid regions; the water resistance was improved and could satisfy the requirements for consolidating the sites in arid regions; the unconfined compressive strength was improved moderately, which was the key direction of improvement in the future, and the consolidated soil did not form duricrust on the surface and had good bonding strength with the internal parts. The BS-10 material can meet the consolidation requirements for the earthen archaeological sites in arid regions of northwest China.
