ABSTRACT |
|
| |
Use of different foaming
agents in concrete mix makes concrete porous at the same time it increases
the volume of concrete. The air entrapped in Foam Concrete can act as
insulator and the pores created by the gas produced from the reaction of
foaming agent and water is discontinuous in nature. These two properties
of Foam concrete can make foam concrete as a good alternative of Lime
terracing. Rigorous investigation on Thermal Conductivity, Water
Absorption, Volume Change and Compressive Strength of Foam concrete, plain
concrete and Lime terracing has shown that use of foaming agent (aluminum
power) to reduce thermal conduction is effective and at the same time
little use of foaming agents do not affects the strength much. And
considering all aspects Foam concrete can be a good alternative of Lime
terracing. |
