Today, hemp bricks are being used to build eco dwellings in the Province of Granada, Spain. Hemp as an industrial produce has been around for thousands of years. After a reporting period slump Hemp BioFuel, it is now beginning to show a re-emergence in this eco-age as a sustainable house product.
Hemp comes from the Anglo-Saxon word ‘haemp’ and is the popular honour for plants of the cannabis genus. Hemp typically refers to the damages of the bush prepared exclusively for industrial use as opposed to cannabis which is associated with cup and same drugs.
Hemp has a huge variety of applications but continues to be overshadowed by the cannabis implication of illegal drugs, with which it is often baffled. Nonetheless, hemp can legally be germinated, under permission, in many countries, including the European Union countries and Canada.
Cannabis sativa L. is the variety primarily stretched for industrial purposes, it is a fast growing bush and has been raised for numerous thousand of years being used to do line, garb, article, hemp oil and drugs. Changing hemp improves the condition of the floor and shortens ambient contamination. It is a robust flora that requires neither herbicides nor pesticides during its cultivation.
Hemp as an industrial material has a ten thousand time history. The first recorded operation of hemp was as a cloth textile, may be in China as far back as 8000 BC.C. Circa 4000 B.C. hemp started to be used, again in China, to form tethers and as meat. 2000 years later, the Chinese hemp oils and drug were in use. By 1000 B.C. its call had spread to India and Greece where the first instances of hemp article were found.
By the 6th century, hemp was being be used in Europe in some surprising spaces, in France a hemp strengthened aqueduct was constructed, and it is still in use today. The hemp fiber also learnt implementations in sailmaking, caulking information, fishing cyberspaces and rows. Later hemp have allowed us to make a anatomy of butter and even brew. By the 15 th century, Renaissance painters were abusing hemp canvases.
Today industrial hemp is used to make a tremendous various forms of products ranging from medicines, body attend makes, building and insulating materials, cloak, textiles, nutrient, ga, sheep food and bedding, plastics and paper.
In the construction industry hemp bricks, because of their sustainability and superb isolation qualities, are being used to construct external and internal walls of green dwellings. In this field of Spain, the outer walls of an eco-house is comprised of an eco-bricks, manufactured in Guadix with the proprietary reputation of Cannabric( r ).
Cannabric( r) derives its assets from industrial hemp fibers( canamo ). The hemp bricks are made up of industrial hemp fibers, slaked lime and a mix of inert mineral cloths. The impedes combine the terms of reference of a load accepting wall that is fire-resistant and is not ask the addition of thermal or acoustic insulation.
The most important component of the eco-brick is industrial hemp which has a very low thermal conductivity( 0.048 W/ m2k) used to produce brick with vastly superior insulation qualities against both cold and heat. The mineral factor of the bricks throws them their mechanical concentration. Being a solid brick, with a high specific hot, it has the optimal thermal owneds to protect against heat.
These attributes induce hemp bricks the ideal selection in areas of southern Europe where there are extremes in temperature through time and winter.
The mechanical fortitude of the cube begin with the process of creating insoluble hydrates. The strong increases over go with the carbonation of the free lime,( a constituent of slaked lime) by humidity and carbon dioxide present in the air. Another important factor in the progressive curing of the eco-bricks is the steady petrifaction of the industrial hemp by the lime and minerals found in the bricks.
Due to its unique form, the hemp bricks give the transpiration and diffusion of ocean vapor between the inside and outside of the building equalizing humidity within the building thus avoiding soggy and cold areas and decreasing distillation on the inside wall surfaces.
Slaked lime acts as the binder, mostly impounding the brick together, but it has other uses. On one feature it protects against moisture by closing any openings and impeding the entryway of irrigate on external faces exposed to flood. On the other pas, it provides protection for the industrial hemp fibers against fungal and parasite attack.
The hemp bricks when laid endwise are for the construction of external walls thirty centimeters thick. The internal walls built with hemp bricks are thinner being half the thickness. The happy, popular cave homes of this area of Andalusia are naturally environmental in that they are re-developed from ancient ramshackle cave rooms. Where ever possible construction sites fabrics worked are salvaged from dilapidated owneds that have been demolished. This recycling minimizes the environmental impact.
It is ironic that this area of Spain, the Altiplano, until the late nineteen sixties, was renown as an industrial hemp germinating area. With the invention and developed at nylon and related commodities, coupled with the conclusion of its Franco area and raise mechanization the primary agriculture of the locality fell apart shedding big numbers of parties out of work. The population of numerous hamlets dropped by seventy-five percent or more, most of the inhabitants migrating to the coast and major metropolitans in search of work.
As a result of these traumatic a difference in demographic the remaining population was mainly aged, the village’s incomes fallen to near poverty level, and numerous empty houses fell into disrepair.
Most of the land workers who moved away lived in cave houses which are now being revitalized by the growing demand for eco-properties.
