The bamboo is known as the famous organic building materials for construction in the old times, whereas some countries still uses it for some small construction. The bamboo is also used as the substitute of steel rebar. But the question is does bamboo can totally replace the rebar. Well both bamboo and rebar have different attributes and different advantages.
Of course the price of bamboo is cheap than the steel rebar but the mechanical properties of bamboo are hard to generalize as steel. The bonding of bamboo with concrete can be enhanced using some adhesives, like epoxy, the technique is an expensive method. The bamboo have higher deflection, wider cracks and lower load or moment bearing capacity than the steel has.
Similarly, the bamboo have the changes according to the situation like, it moisture and temperature affects its properties. And another fact, bamboo is vulnerable to the environment degradation and insect attacks and also not considered as strong material like steel.
There is not any doubt that steel has much more plasticity than bamboo and thus can bear seismic forces without leaving any impact on the building. Also, since bamboo is organic, it have a short life period in comparison to steel reinforcement.
Bamboo has been utilized in development for a long time. Given its remarkable ductile properties, replacing steel reinforcement in reinforced structural concrete with bamboo is of high enthusiasm to numerous architects in nations without their very own steel businesses.
It is a strong, quickly developing plant that is especially appropriate to those worldwide atmosphere zones that are host to an enormous extent of rising economies.
The common type of bamboo presents numerous issues when it is utilized as support in concrete. Bamboo, whenever left untreated, can grow with water and decay. Shrinkage and long haul strength are a portion of the downsides of utilizing normal bamboo in basic solid, which result in its isolation from solid framework. Therefore, it hasn’t been utilized to strengthen concrete with much achievement—at any rate not up to this point
Use of Bamboo and its strength
Presently in structural designing numerous individuals are utilizing bamboo instead of steel for support, however bamboo is an incredible decision for reinforcement in concrete in view of its higher quality when contrasted with steel by weight, the elasticity Bamboo’s rigidity is about 28,000 for each square inch versus steel’s 23,000.Bamboo is more grounded in excess of multiple times of steel reinforcement,On correlation, the vitality expected to deliver steel is just about multiple times that of this regular item. In tensile load application, results appeared by bamboo are energizing in light of the fact that the proportion of rigidity to tensile strength of bamboo is multiple times more prominent than steel.
