Rammed Earth Wall

Traditional Vojvodina house represents an important part of the building stock of the northern Serbian province of Vojvodina. The research examines the thermal transmittance of the walls of rammed earth, which is the basic structural and fa?ade element of traditional Vojvodina house, in two ways: by calculations in accordance with Serbian regulations and by measuring in situ. Parameters obtained from the measurements are compared with the calculated values for the three typical traditional Vojvodina rammed earth single family residential houses. The comparison between the values of the heat transfer coefficient, obtained by the calculation, and the results determined by in situ measurements show significant differences. It indicates that the thermal characteristics are better than calculated ones according to national regulations, but at the same time that, due to the complexity of the rammed earth walls and differences in the rammed earth structures, the results differ from case to case and can not be standardized.

Rammed Earth Wall

Experimental study on the behavior of Single Adobe, Rammed Earth Wall, Single modified adobe block, modified adobe wall and Reinforcement of Bamboo Rammed-earth Wall is put forward in this paper. The experiments include compression, shear and bending test of single adobe, and uniaxial lateral loading test of rammed earth and modified adobe wall and reinforcement of bamboo rammed-earth wall. The mechanical properties of the specimens are obtained through test. The test and research will offer a technological support for the Chinese Government started the Rural House Earthquake Safety Project（RHESP）and formulation of the code for seismic design of rural buildings.

The traditional rammed earth building refers theses structures which uses tools such as pestle or hammer etc to fill undisturbed soil materials after a simple processing by the method of compacting layer by layer. construction technology of the modern rammed earth mainly makes improvements in terms of rammed earth materials、ramming tools and construction technology which can effectively improve the durability and safety performance of rammed earth building. This article is focusing on how to select scientifically which one is the best rammed earth material and introducing improvement situation about construction technology of rammed earth wall, which combined with researching and practicing of pilot project, under the guidance of the International centre for research and application of earth construction.

As the "Fujian earth-building" have been inscribed by UNESCO in 2008 as World Heritage Site, attentions of protection about the "Fujian earth-building" has getting more and more. This article takes samples of a rammed-earth wall from Yongding earth-buildings and determines the shear strength of the samples with different water content through triaxial compression tests. The influence on shear strength of water content of rammed-earth samples is analyzed. Test results show that the shear strength of rammed-earth has much to do with the water content of the soil, the greater the water content is，the smaller the shear strength is. With water content increasing, cohesion and internal friction angle of rammed-earth were decreases, and its changing trend is of marked characteristic of stage. When water contents of rammed-earth is under some value, its cohesion changes in small ranges; when water contents of rammed-earth is over the value, its cohesion decreases with water content increasing.

AbstractFrom November 2012 to May 2013, the Erlitou Archaeological Team of the Institute of Archaeology, Chinese Academy of the Social Sciences found a roughly north-south orientated rammed-earth wall (Q7) and hard-trodden road surface parallel to the wall in the vicinity of the workshop zone of the Erlitou Site. The wall was most likely erected during Erlitou Phase II and continued to be in use until the early stage of Phase IV. The trodden roads took form during Phase II and ended in Phase III or early stage of Phase IV. Together with the previous findings, the excavators postulated two competing propositions on the rammed-earth wall in question. It was the west wall of the walled workshop zone or it was the east wall of a walled enclosure has yet to be discovered to its west. The roads were auxiliary facilities of the walled zone when it was in use.
