The properties of earth as a building materialaciers, water and wind, or through thermal expansion and contraction of rock, or through the expansion of freezing water in the crevices of the rock. Due to organic acids prevalent in plants, moreover, chemical reactions due to water and oxygen also lead to rock erosion. The composition and varying

Improving the earth’s characteristics by special treatment or additivesperties might worsen others. For instance, compressive and bending strength can be raised by adding starch and cellulose, but these additives also reduce the binding force and increase the shrinkage ratio, which is disadvantageous.

Foreknowledge

Direct forming with wet loamilders. The manual shaping of walls from lumps of wet loam or thick loam paste is widespread in Africa and Asia, and is also known in Europe and America. Since no tools are required to work with earth, it is the simplest and most primitive technique. The prepared mixture is used directly (without in

Tamped, poured or pumped lightweight loames of lightweight loams are examined in chapter 4, while chapter 9 discusses how lightweight loam can be used as infill for timber-framed and skeleton structures. Sprayed plasterwork is described in chapter 11. Special designs for walls which give high insulation are discussed in chapter 14, and add

Other factors affecting the composition are the grain size distribution of the sand fraction itself, the water content, the t

Earthquake-resistant buildingrth is viewed a building material for the poor. In this context, it is worth mentioning that a census conducted by the Salvadoran government after the earthquake of January 13, 2001 (measuring 7.6 on the Richter scale), states that adobes houses were not worse affected than other types of constructi
