Abstract |
Concrete is the most used material in the world next to water. Though concrete is very good at compression it is very weak in tension. In order to enable the concrete to overcome the tension cracks the concept of fiber reinforced concrete was evolved.Along with this the self-weight of the concrete is also very high depending on the unit weight of coarse aggregate which is influencing the design and estimation of the structure. This gave a push to work on light weight aggregates using which the self-weight of the structure can be reduced. In the present work it is proposed to identify the mechanical properties at 7days & 28days, and self-weight reduction in the M30 grade concrete with partial replacement of coarse aggregate with pumice stones in volume batching at 10%,20%and 30% variation. Along with this glass fibers are added at 0.1%, 0.2%,0.3% and 0.4% to the concrete. Strength and durability are studies for M30 grade concrete in present work. |
