Structural Behaviour Of Reinforced Concrete Beams Using Expanded Clay Aggregate (ECA)
Nowadays, ECA are utilized in concrete to reduce the demand of natural resources as well as for environmental safety.
This research deals with the structural behavior of reinforced concrete beams made with ECA. The research was conducted in two different phases; total eighteen (18) numbers of beams were tested.In first phase, the ultimate failure load of conventional reinforced concrete beams (CRCB) and ECA based reinforced concrete beams (LCB) were compared.
After noticing the higher load carrying capacity of LCB than that of CRCB, in second phase only LCBs were considered to observe the effect of span length and tension reinforcement ratio on its structural properties.
The ultimate flexural strength, shear strength, short-term deflection, and crack widths were observed and compared with the predicted values obtained from IS 456 and EUROCODE 2.
It has been observed that both Indian and European standards were well predicted the flexural capacity of LCB.
They were more conservative to predict the shear capacity of LCB. The short-term deflection and crack width under service load has satisfied well, the requirement of the design code.
