Abstract
In today situation, in order to accomplish environmental-friendly, the sustainability
environment plays a vital role. This particular study analyses the outcomes from an
investigation on the “The Effect of The Utilization of Cenosphere And Thickness for
Impact Resistance of Leca Lightweight Concrete with Polypropylene Fiber”. The
utilization of Lightweight Expanded Clay Aggregate (LECA) as a replacement for
normal aggregate in lightweight concrete (LC) can promotes its negative environmental
effects.
There is lack of investigation on the impact resistance and crack behaviour of
concrete; exceptionally in Lightweight LECA Aggregate Concrete (LWLAC)
reinforced by utilization of the cenosphere. Through the use of a self-fabricated dropweight
impact test rig, the replication of a low-velocity projectile result on LWLAC
slab 300 mm x 300 mm size with 30, 40, and 50 mm thickness was reached by dropping
two kinds of steel ball (weighing 0.509 kg and 1.05 kg), with completely different of
drop stature. The slab samples are going to be tested by performing of impact resistance
test.
The results show that there was a strong linear relation between amount
percentage of cenosphere and impact resistance; and in crack resistance ratio. This
relation was inalienable by changing the thickness from 30 mm to 40 mm, and 50 mm.
Though increasing the thickness increased the impact resistance fundamentally, the
result was more articulated for ultimate failure crack resistance than for the first crack
resistance. This research likewise is to study the compressive strength, tensile strength,
flexural strength, and flexural toughness of LWLAC containing sand being replaced by
cenosphere by 0%, 10%, 20% and 30%. The outcomes showed the high compressive
strength and density are alluring for good impact resistance of plain concrete, therefore
the utilization of cenosphere increased the impact resistance.
