BEKAERT & KINGSPAN composite slab system

EKAERTBThe Dramix RC-65/60-BNfibre is a glued super perfor-mant steel wire fibre belongingto the higher l/d category.

The use of a Dramix Steel FibreReinforced Concrete slab provides apre-reinforced concrete. No meshhas to be installed.

The KingspanMultideck 60

profiled metal deck provides savings in con-

crete volume compared tomany other decks on the market.

The combined expertise and expe-rience of Bekaert BuildingProducts and Kingspan BuildingComponents, has come togetherto offer the contractor significantbenefits in steel deck construc-tion.

Shear strength The shear resistance of Dramix concrete reinforced with 30 kg/m3 RC-65/60-BN exceeds thatof mesh reinforced concrete. This means that codified checks for longitudinal shear can beadopted and will not penalise fibre reinforced slabs. For 30 kg/m3 the area of fibres crossing ashear plane may be taken as 0,37% of the concrete area.

Shear stud resistanceThe following reduction factors have to be appliedto the resistance of shear studs used in concretewith 30 kg/m3 Dramix RC-65/60-BN:

Recommendations - mixing1. General

preferably use a central batching plant mixer a continuous grading is preferred mix until all glued fibres are separated into

individual fibres. Fibres dont increase mixingtime significantly.

2. Fibre addition

2.1. In batching plant mixer never add fibres as first component in the

mixer fibres can be introduced together with sand

and aggregates, or can be added in freshlymixed concrete

2.2 Truckmixer add Dramix as the final component into the

back of the mixer truck run mixer at drum speed: 12-18 rpm adjust slump to a min. of 12 cm

(with preferably water reducing admixtures orhigh water reducing admixtures)

add fibres with maximum speed of 40 kg/min after adding the fibres, continue mixing at

highest speed for 4-5 min. (70 rotations)

2.3. Pumping recommendations care and attention to the slump and consider a

higher fines content for the mix design. selection of pumping equipment must be care-

fully considered.

Recommendations - storage

Do not stack the pallets on top of

each other

DramixThe complete fibre concept

Dramix fibres are made fromprime quality hard-drawn steel-wire to ensure high tensilestrength and close tolerances.

The glueing of the fibres intobundles guarantees quick andeasy mixing with perfectlyhomogenuous distribution.

A hooked end which slowly deformsduring pull-out is generally considered as the best form ofanchorage.

Some advantages of Dramix steel fibre concrete: ductile concrete with a high load bearing capacity efficient crack control quick and easy application efficient and cost effective solution
