Evaluate the flexural capacity of one-way reinforced concrete slabs cast by using coffor structural formwork

Abstract EN

A newly structural stay in place metallic formwork system named "COFFOR" was used in construction of one way reinforced concrete slabs.

Experimental and theoretical studies were conducted to evaluate the strength and behavior of such slabs.

The experimental program included six one way concrete slabs.

The tested slabs divided into three groups.

The first group represents the reference slabs poured using traditional water proof formwork, while the second and third groups represents slabs poured using COFFOR formwork without and with reinforcement, respectively.

The theoretical study evaluated the ultimate strength of the slabs based on the first principles.

The results showed that the COFFOR formwork can be considered as an additional reinforcement for the slabs and the slabs main reinforcement could be reduced when using COFFOR formwork.
