Abstract
Ferrocement is defined as ‘A thin walled construction, consisting of rich
cement mortar with uniformly distributed and closely spaced layers of
continuous and relatively small diameter mesh (metallic or other suitable
material). It is always a challenge to estimate the force on ferrocement
subjected to DROP weight impact and due to the importance of impacts and
impulsive loads, such as those occurring inaccidental conditions (i): rock
fall on a shelter, vehicles or ships in collision with buildings, bridges or
offshore infrastructures .The main objective of this research is to study
the impact resistance of reinforced ferrocement plates . Research divided
to three parts. first part , five mixes were carried out to select suitable mix
and satisfy the requirements of research .second part eleven ferrocement
plates were designed and cast with dimensions of (500 × 500×25
mm),The ferrocement plates were reinforced with welded, expanded,
tensar metal mesh, with steel bars. All test specimens were tested under
impact load until failure. The impact test was carried out by released a
3.100kg steel ball from a height of 1125mm (1.125m) to the center
surface of the plate (specimen). This process was repeated until failure of
the plate. The total number of bows (impact) which caused the
appearance of the first visible crack(s) and failure of the plate were noted.
This procedure was repeated for all the rest of the plates. Third part ,
plates rehabitated by two layer welded mesh at two faces and by special
mortar . Plates tested again under impact load. Results of reinforced
ferrocement plates emphasized that increasing the number of the steel
mesh layers in the ferrocement forms increases the first crack load,
number of blows to failure and energy absorption. Using steel bars with
steel meshes led to higher energy absorption than that obtained when
using mild steel bars only. Using rubber and fiber achieved high impact
energy .The existence of the fibres and rubber in the mortar mix resulted
in an increase in the first crack, failure load , controlling crack width , and
impact energy absorption. Adding rubber to mortar mix decreased the
loss of weight of plates. Ferrocement plates were developed with high
strength and energy absorption properties which could be useful for
developed and developing countries alike.
