(especially in kitchens and bathrooms) can be dealt with by painting them with casein, lime-casein, linseed oil or other coatings, which makes them nonabrasive As explained on p 132, bathrooms with earth walls are more hygienic than those with glazed tiles, since earth absorbs high humidity quickly, thereby inhibiting fungus growth 1.20 Prejudices against earth as a building material Owing to ignorance, prejudices... always easy to produce building material out of a clayey soil, and experience is required The right preparation depends on the type of earth, its consistency and its expected application Moist crumbled earth with less clay and more sand content can be used immediately to build a rammed earth wall even as it is dug out Clods of earth with high clay content cannot be used as a building material; they... Though in DIN 18952, soils with binding forces below 50 g/cm2 were not recognised for building purposes, tests on a variety of historic rammed earth walls in Germany showed that some of these, in fact, had much lower binding forces, and one sample was even as low as 25 g/cm2 2.36 2.32 Comparison of indoor and outdoor air temperature of a building with adobe vaults (above) with one using prefabricated... the binding force, and therefore that loams with equal binding forces should fall within the same range of permissible stresses for use in buildings (see 2.35), Properties of earth is disproved by Gotthardt (1949) and by the BRL By Niemeyer’s extrapolations, a loam with a binding force of 60 g/cm2 would have a permissible compression of 2 kg/cm2, and a loam with a binding force of 360 g/cm2 would have... described on p 32 For earth construction, the direct tensile strength of the dry material is of no relevance, because earth structures must not be under tension Table 2.38 shows that dry tensile strength is about 10% of compressive strength with blocks, and 11 to 13% with earth mortars Bending tensile strength The bending tensile strength of dry loam is of little importance for earth construction Still,... entire roof structure rest on the solid rammed earth walls that are 75 cm thick at the bottom and 40 cm thick at the top floor (the compressive force at the bottom of the walls reaches 7,5 kg/cm2) Illustration 1.12 shows the facades of other rammed earth houses at Weilburg, built around 1830 Earth as a building material: the essentials Earth, when used as a building material, is often given different... in water and thinned with sand This chapter describes the different possibilities of preparing earth for specific applications 36 Preparing of loam There are several methods available for making workable building material out of clods of earth One of the easiest methods for reducing the size of clods and making their consistency workable without mechanical labour is to place the earth clods in water... effect of material and building shape on interior climate is shown by readings taken from two test buildings of equal volume constructed in Cairo, Egypt, in 1964 One was built of 50-cm-thick earth walls and mud brick vaults, and the other of 10-cm-thick pre-cast concrete elements with a flat roof While the diurnal variation of the outside temperature was 13°C, the temperature inside the earth house varied . aggregate I2 with 2.0% coconut fibres C1 with 2.0% cellulose fibres E1 with 2.0% water glass I1 with 1.0% coconut fibres L1 with 3.0% saw dust J1 with 2.0% wheat straw F1 with 3.0% cement D2 with 2.0%.
