Arizona Shop Structure I have a strong interest in alternative construction techniques that fundamentally make sense even if the ‘how-to’ phase hasn’t been documented for decades and accepted into building codes--because code allows so many people to live in drastically energy inefficient, burnable, rot prone structures that use a lot of materials which are suspect in terms of human health. I moved to rural, southeastern Arizona because the high desert climate agreed with me and there were no building codes here, which allowed me to try a variety of alternative construction projects on my property. My first experience with alternative buildings was via my neighbor out here, who built a strawbale house which burned to the ground inside of half an hour. The ideal situation would be thermal mass with insulation on the outside, but not rigid foam as is used throughout the southwest- it creates a vapor barrier which is destructive to earth based structures such as adobe, rammed earth, cobb or earthbags.

Alternative Technology Association website Hemp Construction using Natural Lime from St Astier Hemp is a natural material suitable for making light weight insulating mortars. Its density vary between 110 and 150 kg. per m3. The strands are between 5 and 25mm long. Particular attention has to be paid in making sure that hemp is not subject to dampness either due to stocking conditions of the raw material or capillary action in hemp mortars (adequate damp courses if constructing walls or insulating/draining ballast base in concrete should be in place). The qualities of St. In comparison with other products using hydrated lime with the addition of hydraulic binders (cement)/pozzolans, Batichanvre ® contains 25% less additions due to the use of St. INSULATING HEMP/LIME CONCRETE Dosage: 1 bag of Batichanvre ® ( 25kg) + 100 litres of hemp + (optional) 5 litres of coarse sharp sand (5mm down)Water addition : 35 to 40 litres Application Directly on soil: on a well levelled and compacted soil, if necessary stabilised , construct a 15-20cm. ballast base. Do not use any plastic sheeting.

The chemical equation for this reaction is CaCO3 + heat → CaO + CO2 Early lime use[edit] Types of kiln[edit] Permanent lime kilns fall into two broad categories: "Flare kilns" also known as "intermittent" or "periodic" kilns; and "Draw kilns" also known as "perpetual" or "running" kilns. Early kilns[edit] Cross section of typical early kiln The common feature of early kilns was an egg-cup shaped burning chamber, with an air inlet at the base (the "eye"), constructed of brick. Only lump stone could be used, because the charge needed to "breathe" during firing. Sets of seven kilns were common. A 'lazy kiln' was how kilns were called if they were only used rarely.[10] Great Britain[edit] The large kiln at Crindledykes near Haydon Bridge, Northumbria, was one of more than 300 in the county.

GDES 4365W: November 2010 Archives Almost everyone these days is concerned about the environmental preservation, but it feels like we, as consumers, are not always willing to sacrifice convenience and change our habits or consumption to make a serious commitment to the environmental agenda. There are many fair reasons why we can't commit, the strongest being the lack of financial resources to purchase environmentally friendly products. There is also a lot of concern about "greenwashing," which drives people away from so-called green products because of potential unsubstantiated claims about their ecological benefits. It is easy to see that we have found ourselves in a situation in which there is a strong social need for environmental protection, but an inability to match that attitude with action. Hotels have found many green cleaning options actually save them money, or are at least are price neutral, compared to traditional cleaning products. Works Cited: Glanville Consultants.

Limestone Limestone makes up about 10% of the total volume of all sedimentary rocks. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock. Limestone has numerous uses: as a building material, as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, and as a chemical feedstock. The first geologist to distinguish limestone from dolomite was Belsazar Hacquet in 1778.[1] Description[edit] Cutting the limestone blocks at a quarry in Gozo, Malta Like most other sedimentary rocks, most limestone is composed of grains. Limestone often contains variable amounts of silica in the form of chert (chalcedony, flint, jasper, etc.) or siliceous skeletal fragment (sponge spicules, diatoms, radiolarians), and varying amounts of clay, silt and sand (terrestrial detritus) carried in by rivers.
