This stratification allows the proportion of the constituents to be estimated. One was built of cm-thick earth walls and minoe brick vaults, and the other of cm-thick pre-cast concrete elements with a flat roof. With sandy loam mixtures with little clay content, a diameter of 50 mm is not attainable.

The water con- tent which gives the highest density is called the optimum water content. Loam has a specific heat of 1. The addition of cut straw, however, has the opposite effect, as shown by investi- gations carried out at the BRL see table 4. There is worldwide debate over which type of straw is most suitable, and it should be tested in each case.
Despite mechanised production of soil blocks using presses, the output per person per day is only to blocks, considerably less than that of the primitive method involving throwing loam into moulds. This depends not only on the quantity and type of clay involved, but also on the grain size distribu- tion of silt, sand and larger aggregates, as well as on the method of preparation and compaction.
Mud brick adobe houses dating from to BC have been discovered in Russian Turke- stan Pumpelly, If the free length before breakage is more than 20 cm, then it has a high binding force, implying a clay content that eith too high for building purposes. As can be seen in the same figure, vertical cracks can also occur in such walls.
The methods for treatment and additives for increasing the compressive strength of loam are discussed on p. Therefore, there is a higher shrinkage in 5. The higher the porosity and the larger the pores, the higher loam’s resistance to frost. Its binding force is then usually insufficient, and it can- not be used as a building material.
In hot dry and temperate climate zones, earth offers numerous advantages over other materials. Cort rated it really liked it Jul 09, The results of this method are shown in 4. Want to Read saving…. In Europe, timber panels of 19 mm thickness are commonly used. The loam-clods are placed in large flat containers in a layer 15 to 25 cm high and then covered with water.
This is attributable to the fact that relative clay content is reduced and a certain amount of water is absorbed into the pores of the fibres.
The absorption curves of different loam mix- tures are shown in 2. These spacers pierce the wall, causing openings that must be filled in after removal of formwork. Refined formwork systems and electrical or pneu- matic ramming reduces labour input signifi- cantly and makes rammed earth techniques relevant in some industrialised countries as well.
The proportion of the components is commonly represented on a graph of the type shown in 2. The advantage of this procedure is that since no foreign substances remain in the water, the phosphates are converted into calcium phosphate for reuse as a fer- tiliser.

Theoretically, a weather-resistant coat of paint is sufficient as protection, but in prac- tice, cracks often appear on the surface or are created by mechanical action. Plant products Plant juices containing oily and latex and derived from plants such as sisal, agave, bananas and Euphorbia herea, usually in combination with lime, are used as a stabil- ising coating with success in many coun- tries.
If the diameter of the disc is less than 50 mm, then a few drops of water should be added. Influence of heat The common perception that earth is a very good material for thermal biulding is unproven. Silt, sand and gravel The properties of silt, sand and gravel are totally different from clay.

A similar effect can be seen in 4. There are no discussion topics on this book yet. Jarek Esquela rated it really liked it Dec 13, On the contrary, the decisive parameters are worka- bility and binding force; hence it is recom- mended that loam should not be used with optimum water content as per DINbut instead with a water content somewhat higher than the optimum so derived.
It has proven impossible to fulfil the immense requirements for shel- ter in the developing countries with industri- al building materials, i. This in turn creates movements that allow the particles to settle into a denser pattern. The pouring is stopped when the sample breaks. Structural measures The simplest method for reducing shrink- age cracks in earth building elements is to reduce their length and enhance drying time.
A stronger mixture is obtained with 24 parts expanded clay 8 to 16 mm5 parts expanded clay 1 to 2 mmand 5 to 7 parts loam.

In comparison with adobe masonry see chapter 6rammed earth – since it is monolithic – provides the advan- tage of longer life. There also exists a variety of buiding common clay minerals such as lllite.
For more details, see p. The historical core of the city of Shibam, Yemen, covering about 20, m 2 and accessible only through a single gateway, was built entirely in adobe. The simplest method that can be used is to throw the dry material over a sieve. Weiss also suggests that the high strength of porcelain comes from Kaolinite soaked in putrid urine which contains urea and ammonium acetate. Mixing While forced mixers are usually required to produce loam mixtures see chapter 3, p.
As the liquid and the plastic limits have been defined using a mixture containing only particles smaller than 0. Lukas rated it it was amazing Nov 28, His book Building with Straw was also published by Birkhauser.
