In the mix


In its second year at SED the Concrete Show has grown by 30%, making it bigger and better than last year. This year, visitors to the only UK event focusing solely on concrete construction, repair and products, can expect to see more than 75 specialist exhibitors.

Once again the Concrete Show will be staging a series of live demonstrations between 10.30am and 4pm each day in a purpose-built arena within the Concrete Show pavilion. This year's programme will feature many new techniques and products not previously seen at the show. Visitors will be able to see, live in action, the latest in decorative concrete finishing on freshly laid and cured concrete, the addition of steel and polypropylene reinforcement fibres, a hand-held rebar tying machine, concrete vibration equipment and a control joint dry cutting system.

"The inclusion of these products in the demonstration programme gives the construction professional a superb opportunity to see the latest equipment available to the UK concrete industry, in real job site operating conditions," says Daniel West, show director of the Concrete Show at SED.

The daily programme (see box, p58) also includes concrete pumping, power trowelling, screeding, all that's available in surface preparation, floor formwork and a cementitious flooring system. Entry into the demonstration arena is free and attendees will also have the opportunity to direct questions to experts in each of the demos.

Several newcomers will be appearing at this year's show, many of which will be displaying products not previously seen at the event.

"The increase in the product ranges on display certainly helps establish the Concrete Show as an all-encompassing event for the concrete construction industry," says West. "In addition, the growth of the number of companies displaying admixtures and materials is helping confirm this as not just an event just to source concrete equipment," he adds.

HTC Sweden, a producer of floor grinding equipment for the construction industry, has developed a system called 'Superfloor', which it claims is the "new industrial floor for the future". Live demonstrations of the HTC system will take place at its stand.

Three Terminator machines will be showcased: the Terminator 2000; Terminator 2000e (battery powered); and the Terminator lite 1500. All are said to be compact, with a wide range of abilities, manoeuvrability and strength. The heavier models can remove ceramic tiles, epoxy coatings, paints, latex and adhesive residues, while the 1500 machine can remove VCT, carpet, sheet vinyl and associated residues.

Trelawny Surface Preparation will exhibit its five newest products: the TFP 250 machine, which is designed as a robust floor scarifier; the TCG 500, a dual counter-rotating disc concrete grinder designed for smoothing concrete surfaces, removing high spots and texturing floors for non-skid applications; the Challenger VL303 Needle Scaler, which has a vibration level of only 2.3m/s2; the Reduced Vibration Single Scabbling Hammer, with its single piece piston and tungsten carbide-tipped cruciform head; and the re-developed Vibro-Lo concrete pole scabbler, designed for additional operator comfort without loss of power.

Exhibiting and demonstrating at the Concrete Show for the first time, Young Black Industrial Stapling will showcase its range of MAX rebar tying tools and other selected products. The battery-powered machines are said to produce ties three to five times faster than by hand with consistent performance and minimal training - giving more production for less cost.

Somero Enterprises' S-9210 Copperhead Laser Screed will be launched at the show and is said to take the backache out of placing concrete. The Copperhead offers the benefits of laser screed technology (consistent floor quality, increased production, lower labour costs and better health and safety), in a package about the size of an industrial lawn mower. The laser guided, hydraulically propelled machine is said to give extremely accurate results on poor ground and for structural reinforcement. It is equally suitable for large or small projects with a concrete thickness of up to 250mm.

Armcon's Cemen-Tech mixer can now handle recycled materials due to the "unique", larger mixing auger which gives high-shear fast mixing of recycled aggregates. Armcon's new Armfoam chemical has been introduced to the mix allowing density to be controlled and quality foam concrete manufactured. Armcon's director, Bob Armstrong, told CJ: "This increased versatility of the Armcon mixer will be of particular interest to customers serving the utility, local authority and highway sectors wishing to enhance their environmental policy and reduce costs."

Each mixer carries its own raw materials and produces concrete to any mix design, with exact quantity drops at the point of usage. There is no waste and trucks can move between customers without having to return to base. Armcon supplies vehicles with capacities of 4m3, 6m3 and 8m3 and a production rate of 1m3 every two minutes.

Civil & Industrial Products will highlight the benefits of the Densiphalt jointless surfacing system. It says the system's advantages include 24-hour curing, slip resistance, resistance to rutting and freeze-thaw properties. The company says it had success with the system on jobs like Stand 50 at Gatwick Airport's North Terminal, where BAA selected Densiphalt as the refurbishment solution for replacing 1,000m2 of surfacing. "The rapid early strength gain of the Densiphalt proprietary microsilica based mortar meant that the stand could be reopened to aircraft after 24 hours," says the company.

Oxfordshire-based K-Form will unveil its K135 Roadform, which it says is an innovative and cost-effective alternative to conventional metal shuttering. "Lightweight and durable, this high performance system provides strength and flexibility and is easy to install. K135 dispenses with the need for flexible joint fillers, diamond cutting, the removal and cleaning of steel formwork, and offers substantial time and labour savings."

In addition to its Revolution diamond blades and Ultima core drills, Nimbus will feature the new range of Braun wall saws, wire saws and drilling equipment. Live demonstrations will include wall sawing using the new Braun machines, chain sawing with the ICS machine and core drilling using the latest auto-feed drill rigs. Other new products will include drill stands, drive motors and bursters.

Utranazz will exhibit its new range of low-level, fully transportable batching plants with outputs from 50m3 per hour and a choice of two-, three- or four-bin configuration. The low-level cement silos have capacities from 20t to 60t, complete with electronic weigh batching equipment, off-loading legs and fully computerised control panels. Also being shown for the first time will be the Sermac truck-mounted concrete pump fitted with a 32m, five section underfold placing boom and mounted on a 6x4 Mercedes chassis.

Permaban will demonstrate Permasteel, the latest development in its "leave-in-place" formwork range. Permasteel is available in four heights for slab depths ranging from 50mm to 300mm. While it can be effectively used on the ground, Permaban will demonstrate its use as a metal deck levelling guide, where tests have demonstrated that it can increase a contractor's ability to gain a greater degree of flatness on these difficult surfaces. Also featured will be a new curing agent/seal used for the fast-track Permashake range of coloured dry shake concrete floor hardeners.

On the Wacker stand, visitors will be able to view the latest five bladed, twin rotor trowel with its unique drive train and easy overlap adjustment. Staff will be demonstrating the ultra low hand arm vibration IRFUN poker for compacting concrete, the CT trowel and a new floor saw.

Advanced Construction Materials manufactures specialist flooring, maintenance and refurbishment products for contractors, builders and other end users. It will exhibit its Monoflor SL, a steam cleanable, non-shrinking, self-levelling polyurethane flooring system available in a range of colours.

The 80M3/H concrete batching plant, one of a full range of off-the-shelf modular and customer specified concrete plants, will be on the Ocmer stand.

The latest release of its computerised plant control system will be on Elettrondata's stand. The new system has polynomial and interpolated batch book recipe entry, automated moisture control and slumping station software as well as full record and invoice printing.

Bentley Chemicals will show its range of Smooth-On PMC, Evergreen and Brush-On of urethane rubbers and the Rhodorsil RTV silicone elastomers for concrete moulding. On display will be examples of Duo Matrix Neo (high strength gypsum) and Matix 'C' (high strength concrete). Bentley will also introduce Reoflex, a new generation of low viscosity, high strength urethanes from Smooth-On. They are available in several hardnesses and either dry or wet, to aid demoulding.

A number of new developments will be exhibited on Steelfields' stand, including the Major 2000 (which can produce impressive quantities of quality wet, dry or half wet concrete) and the 2000E, an economy version. New mixer developments include: the diamond carbide surfaced UltraHard wear plates; mixer washout systems; and a system for measuring levels of material in a silo.

Putzmeister will exhibit its new BSA702D trailer-mounted concrete pump and the Dynajet range of pressure washers. Also on show will be the Mixoket M760HD screed conveyor and SP11 worm pump. Completing the line up will be a truck-mounted concrete pump and the Putzmeister Pumi returning to the show to deliver concrete for the demonstration area.

Elkington Gatic will feature its Gatic Slotdrain surface water drainage system. Supplied in 3m lengths, the system is said to offer significant benefits over conventional channel drainage, as it is durable, easy and quick to install, and it provides an attractive finish without the hazards experienced with loose gratings.

So if you're looking for the latest in batching and production, admixtures and materials, or you want products for placing and finishing, or repair and demolition, then it's all there for you to see at this year's Concrete Show, which will continue to be located directly at one of the two entrances to the SED show site. n
