Properties Among the characteristics of the Guadua is its extraordinary firmness to compression and a good resistance to the parallel cut, this added to the great flexibility that presents turn the Guadua cane into a tool especially interesting for the bioconstruction, where this catalogued as structural material seismic-resistant. They usually grow at low altitudes below 1, mbut has been found up to 2, m. The bamboo does not increase its diameter with the passage of time, but emerges from the soil with its diameter determined, being ajgustifolia monocotyledonous it lacks cambium tissue so it does not get fat like trees….

The mixture prevents the proliferation of insects without using poison thanks to the intrinsic structure of these borax salts, hard and angular so that if a xylophage attacks the cane, these small sharp angstifolia pierce its stomach preventing the insect from continuing with its life cycle. A Review of Engineering in Everyday Life. If this is done well, a rhizomatic energy transfer mechanism begins in the plant and a new culmo begins to be generated, so that new production is guaranteed.

The Guadua stems, with angistifolia more than 20 m. The Guadua angustifolia, native to Colombia, is the most important of these thanks to its extraordinary physical-mechanical properties and the progress in the silvicultural and structural study that has been carried out in the country in recent years.

Its diameter is constant for the first 15 meters and then tapers at the top. As an added advantage, all materials treated in this way have fire-resistant properties thanks to borax.

The intermediate sections or Basas are slender and very light in relation to their enormous strength, maintain the outer diameter very well and are very fibrous so they are the most used parts in kuntg, especially in the manufacture of beams and composite trusses.

Before introducing the reeds in the dissolution, all the internodes of the reeds are perforated, on the one hand this facilitates the immersion because it allows the air to escape vuadua the inside of the reeds and the reed stops acting as a anbustifolia, and on the other hand it allows the entry of the mixture into the different sections of the reed, thus ensuring a correct preservation because the bamboo is much more permeable from the inside.

Environmentally, Guadua is more effective at removing carbon dioxide from the atmosphere than most other tropical forest [ citation needed ] ; ongoing studies in Colombia have now been coordinated by the Lunth Bamboo Foundation.

The high percentage of fibre present in guafua structure and the high content of silica in its outer face make this species present the amazing characteristics of resistance and flexibility that characterize it.

For architectural purposes, Guadua is the preferred bamboo species. In the vines can reach more than 3 cm, used in pillars or where a lot of work is received by compression while in the bases can be between 0.

Harvesting can begin six years after planting, making bamboo a potential source of tropical biomass production for industry e. Bamboo propagated in a laboratory in the space of one square meter will be sufficient to establish one hectare of new forest.

Protection by Design and Maintenance When building with bamboo on the outside as with any timber it is necessary to take into account the action of the sun on the surface of the reeds. Vegetal materials in construction.

Missouri Botanical Garden, St. Bamboo construction is also earthquake-resistant. Or, Guadua can be propagated more rapidly by the chusquin method. To prevent the bamboo from being attacked by xylophagous insects and to prevent fungal growth, the canes are immersed for days in a solution of borax and boric acid at a ratio of 1: Since bamboo is a grass, harvesting it down to the soil induces more new shoots to angustifoliw, just like angustifoliaa grass.

Although bamboo culms used for guavua can be harvested in natural forests, over-exploitation leads to the depletion of natural resources.

The groups of these Bamboos form the so-called Guaduales, spectacular forests where it is generally possible to enter because they are not particularly dense and that give rise to very dynamic and highly specialized ecosystems. Biennale of Architecture University of Southern California.

These formations are very important even in distant areas guarua among their main functions they are water flow regulatorsabsorbing water when there is excess and gradually releasing it to prevent possible flooding, prevent soil erosion and deforestation thanks to their underground branches, contribute a large amount of biomass to the land and are one of the largest environmental CO2 fixers on the planet with records of between and tons per hectare in each life cycle, from 4 to 5 years.

The preservation by Immersion in Pentaborate is considered friendly because its functionality does not depend on a toxic but on salts, a natural and innocuous product at these concentrations.

It is common for some cracks to appear in the bamboo, always longitudinal, which do not pose any structural problem as the properties of bamboo remain practically unchanged. The reeds obtained from the highest section, called Sobrebasa, have thin walls but maintain a kunrh fiber content. The cage and the beast. A preservation technique, involving the use of non-toxic smoke can prevent bamboo’s deterioration for several decades [ citation needed ].
