A study of the feasibility of using bamboo as the reinforcing material in precast concrete elements was conducted at the U. S. Army Engineer Waterways Experiment Station in 1964.
Ultimate strength design procedures, modified to take into account the characteristics of the bamboo reinforcement were used to estimate the ultimate load carrying capacity of the precast concrete elements with bamboo reinforcing.
Bamboo was given recent consideration for use as reinforcement in soil-cement pavement slabs in which the slabs behave inelastically even under light loads. For this case ultimate load analysis was shown to be more economical and suitable for use.
The following factors should be considered in the selection of bamboo culms (whole plants) for use as reinforcement in concrete structures:
1. Use only bamboo showing a pronounced brown color. This will insure that the plant is at least three years old.
2. Select the longest large diameter culms available.
3. Do not use whole culms of green, unseasoned bamboo.
4. Avoid bamboo cut in spring or early summer. These culms are generally weaker due to increased fiber moisture content.
We find that using shuttering for the structure is the most cost effective way to construct a structure.
ReplyDeleteThis is called "total design concept"
The formwork for these structures included all elements, structural, non- structural, and architectural. The architectural elements include, radius headers, decorative columns, pitched concrete roof, and rain gutters cast directly into the decorative moldings. Casting all elements achieves a cost savings of 10-20% over traditional methods. Casting all elements also speeds construction 30 - 50% over traditional methods. This is achieved by the speed of the formwork system, the reduction follow on trades, and the ease of finishing the surfaces.
Bamboo is consider as a wood. Shrinkage is nature of wood.
