For example, traditional English cob, which was used up until the 1800s when it began to be replaced by more modern construction methods, was a mixture of clay-based subsoil, sand, straw and water. In the UK we ensure our cob houses last for hundreds of years by incorporating a few basic design features that make them suitable for our climate. We know 308 definitions for COB abbreviation or acronym in 8 categories. Sieve analysis: The sieve analysis results is presented in Table 1, the results shows that the mixture contains good percentage of coarse aggregates, more than 50%, while percentage silt and clay is also more than 15%, this is still acceptable, however the plastic index will also be used to further determine its suitability. The full length of it means “close of business” and it represents the time when you are supposed to go home from work. A straw content of about 1.0 to 1.5% is probably optimal when all of the above factors are considered. Please look for them carefully.

This is partly due to no allowances for densities silt and clay. The soil sample used was obtained from a site in front of the Federal polytechnic Ado-Ekiti, in Nigeria. High moisture content will also affect and eventually reduce the durability of straw, leading to a greater potential loss in strength for cob with higher straw content. If too much straw is added, the extra water needed also leads to increased volume changes during drying however the straw reduces the size of cracks. For part 1, 36 specimens were prepared, 12 of which were axially unconfined compression tested immediately after preparation to determine their initial wet strengths, the other 24 were allowed to air dry in the laboratory 12 of which were unconfined compression tested (and loaded in excess of that of failure to help clarify the failure mode). Production of Cob: The production of cob involved three stages. Cob construction can save money, resources and time … Typically contemporary cob has beautiful curvilinear walls and many sculptural details. Also straw content of about 1-1.5% gave the highest compressive strength at optimum moisture content of 2-4%. In the present study, the aggregate fraction is that fraction of the matrix material with an effective diameter greater than 0.002 mm; the binder fraction has an effective diameter less than 0.002 mm. Cob is an ancient technique of building, which is a combination of sand and clay, mixed with straw and water. cob definition: 1. the hard cylinder-shaped part of the maize plant on which the yellow or white grain grows: 2. a…. Ease on mixing: From the mixing processes carried out, the soil was clayey but required less time for mixing and it was easier for straw to adhere to it, this is due to the plasticity index and the liquid limit results which are 23.8 and 40.5%, respectively, while the plastic limit is 16.7%. It also provides excellent thermal insulation, generally exceeding minimum U-values for domestic buildings. cob wall "A wall formed of unburnt clay mixed with chopped straw, gravel, and occasionally with layers of long straw, in which the straw acts as a bond"- Dictionary of Architecture and Construction, Cyril M.
