Abstract
The objective of using materials is to fully utilize the properties of these materials in order to obtain the best performance of the structure. The merits of material are based on many factors like, workability, structural strength, durability and low cost. Ferrocement is an excellent construction system. This paper studies the behavior of ferrocement circular slabs under impact load. The experimental program include testing four sime fixed supported ferrocement circular slabs of 800mm diameter and 50mm thickness. The Influence of the use of styropor voids was investigated in different ratios (24% and 48%) and a number of wire mesh layers four and six layers. Impact load test results revealed that increasing number of wire mesh from 4 to 6 led to an increase in the impact energy for first crack by (41.991% ,37.62%) respectively when using voids ratio by (24% and 48%) respectively and impact energy for full perforation by (21.7% and 9.94%) respectively when using voids ratio by (24% and 48%) respectively. Ferrocement circular slabs are used in construction fields such as roofs, tanks, manholes, etc.
Highlights
Sandwich panels have gained much attention as an effective structural form in the building and construction industry
The main aim of this research is to investigating the effect of voids ratio and number of wire mesh layer on the structural behavior of ferrocement circular slabs subjected to impact loading
The widely used test is a type of the drop-weight method, that can be utilized to evluate the relative performance of composites throughout determining the energy absorbed required to cause first crack and full perforation
Summary
Sandwich panels have gained much attention as an effective structural form in the building and construction industry. Sandwich panels offer high strength-to-weight ratio causing substantial reduction in the self-weight of the structures. The self-weight of the element with high density (weight) itself accounts for a major portion of the total load of the structure. The use of sandwich panels with cores of lightweight concrete is spreading due to their manufacturing efficiency that leads to the industrialization of the building system [3]. Sandwich panels typically consist of two thin, high strength and density outside face sheets known as skin separated by a thick layer made of low strength and density material called as core [4]. Before fall is subject to high deflections It is durable, economic cost, lightweight, weather resistance, and its versatility for comparing with the reinforced concrete [11].
