Abstract:

Investigations on the characteristics of Fibre Reinforced Concrete (FRC) have gained momentum in the last fewdecades. Employing suitable polymeric fibres and additives in concrete to improve its performance is an important consideration in the construction industry. This research aims to investigative the effect of polypropylene (PP) fibre volume percentage within the concrete mix with and without the presence of polymeric materials on the rheological properties of concrete and its behaviour under compression. PP fibres exhibit low elastic modulus, high elongation and are of low cost, making these fibres most suitable for inclusion in Polymer Modified Concrete (PMC). Traditionally, PP fibres are used in concrete to reduce plastic shrinkage and micro cracking.Accompanying PP fibre additions to PMCs are often styrene butadiene (SB) copolymer latex additions; used to improve the bonding of PP fibres in the cementing matrix. This paper reports on the findings of using different percentages of PP fibres with PMCs incorporating 10% SB latex and 30% fly ash (FA) for partial replacement of Portland cement. Slump, mass per unit volume, air content, high range water reducer agents amount and compressive strength, will be assessed and compared to plain concrete devoid of PP fibre, SB latex and FA additions, after period of curing applied at 7, 28 and 56 days of ageing. © 2013 Taylor & Francis Group.
