Product Name	Key features and specifications	Benefits	Applications
Fibre Concrete	Polypropylene microfibres All grades Slump - 100mm +/-25 Steel Fibres: All grades - 20 kg min, Slump - 75 +/-25 (Dosage will depend on specifications)	Reduces plastic shrinkage cracking Replaces the secondary steel (mesh) reinforcement in floors	For non-structural slabs on the ground, such as driveways Structural slabs on ground
Early Strength Concrete	All grades, Slump - 75mm to 90mm +/-25, Strength - 18MPa a t 72 hours from last concrete delivered Strength - more than 10MPa at 24 hours or more than 20MPa at 72 Hours Rapid strength development using calcium aluminate binder, Min. 400kg/m3 cement and w/c below 0.4	Achieves 18MPa at 72 hours, for post tensioning Gain time on job site Can achieve minimum 30MPa at 8 hours	Precast, building construction using formwork involving post tensioning Horizontal and vertical applications Airport runways / Road repairs / Emergency repairs to any concrete structure
Flowable Concrete	All grades, Sump - 160m to 200mm, special admixture ensures slump retention for 90min, Reduced shrinkage, aggregates 26mm or less Flow over 640mm with 2 hours slump retention, viscosity 6 to 8 seconds with 0 funnel, Aggregates: 13mm or less Mix formulated for horizontal applications Flow over 640mm with 2 hours slump retention, viscosity 6 to 8 seconds wiht 0 funnel, Aggregates: 13mm or less, Mix formulated for vertical applications	Flowable concrete from the plant to the job site, addition of extra water must be prevented, better finishing (less bleeding, less cracks), better workability and easier to cast Easy to place and finish (will require technical assistance) Easy to place and finish (will require technical assistance)	Pumping in horizontal applications, such as slabs or driveways, vertical formwork applications Used for floor slabs and toppings, can be pigmented, necessity of curing with a Lafarge curing compound Difficult access areas, congested reinforcing, specialised repairs, architectural finishes, necessity of curing with a Lafarge curing compound
Waterproof Concrete	Spec to suit requirement, using Xypex admixture, Min. c/w=1.9 Min. cementitious 300kg/m3, Site control very important, All contracts to be discussed with Xypex	For high spec waterproof requirements, warranty provided if Xypex site service is used	Water tanks, basements, floor slabs, decks
Pool Concrete	Semi-dry concrete specially designed for handpack operation (slump below 75mm), can add polypropylene fibres	Quality and consistency of the concrete	Lining swimming pools and ponds
Foam Concrete	Low density 1200-1500kg/m3 or 1600-1800kg.m3 concrete with a compressive strength of 3 to 5MPa	Low density concrete allowing easy removal if necessary	Trench, tank reinstatements, non structural insulations
Light Concrete	Light weight 25MPa concrete, perlite or polystyrene beads used to achieve a density below 1100kg/m3	Light weight concrete	Lightweight work
Industrial Floor Concrete	High strength, low shrinkage concrete freatures reduced curling, with of without fibres, Min. strength 30MPa, achieves flatness less than .045 micron/Lm, slump 75mm, Cement min. 310kg/m3, Max. 20% extender, W/C max 0.53	High performance concrete	Industrial floors
Aqua Concrete	Underwater concrete mixed to suit job specification, Min. 30MPa	Under water application	Under water construction
Piling Concrete	Dry or semi dry piling mix, 30MPa 30Mpa Tremmie mix for piling applications, slump - 180mm to 220mm 30MPa Grout mix, 20 sec flow through a Marsch Cone	Specialised piling mix for dry applications Ease of placement with Tremmie pipes Used where pumping grouts is an advantage	Piling Piling Piling
