Effects of Fibre on Drying Shrinkage, Compressive and Flexural Strength of Lightweight Foamed Concrete

Article Preview

Abstract:

The present study covers the use of fibre in lightweight foamed concrete (LFC) to produce the lightweight concrete for use in construction of non-load bearing elements. LFC with 600, 1000 and 1400 kg/m3 density were cast and tested. Polypropylene fibres with different percentage were used into LFC and the resulting products were compared to normal LFC. Compressive strength, flexural strength and drying shrinkage tests were carried out to evaluate the mechanical properties up to 180 days. The addition of fibres in LFC showed no contribution on compressive strength but improvement in the flexural and shrinkage test results.
