It has been widely used as an overlay material for concrete bridge deck repair because of its short curing time, high durability, and high bond strength. In this experimental study, VES-LMC was used as the overlay material. The concrete for the base slab was made with ordinary Portland cement and a maximum aggregate size of 25 mm, with target strength of 39 MPa. The bond strength of the VES- LMC overlay was evaluated for these three surface conditions of the base slabs: (1) treated with a spin jet; (2) treated with a pneumatic breaker; (3) untreated.

It was found that the tensile bond strength is the highest when the base slab was treated with the spin jet (1.72 MPa). It was 28 percent higher than that of the untreated surface (1.34 MPa) and 51 percent higher than that of the breaker-treated surface (1.12 MPa).

Based on visual inspection, it was found that, in the case of the untreated surface, the dominate failure mode is interface failure. But in the case of the

Many of these members contribute articles to Jet Significant Events In WJTA History continued on page 11 News.

A major accomplishment of the WJTA has been the development of safety manuals. Historically the majority of waterjet accidents have occurred while using manually operated high pressure waterjetting equipment. In response to these accidents, WJTA published and distributed the safety manual, Recommended Practices for the Use of High Pressure Waterjetting Equipment. This manual outlines the safety practices that should be followed when operating manually operated waterjet equipment. This manual is a reference tool in most waterjet company safety manuals and is used as a reference in court proceedings. To date, WJTA has sold nearly 28,000 of the English language version of this booklet and 900 copies of the Spanish language version. In addition, 750 videos and 300 CD- ROMs of the content of the safety manuals have been distributed to the public.

Industrial vacuum equipment is often used in conjunction with waterjets. WJTA developed a safety manual, Recommended Practices for the Use of Industrial Vacuum Equipment. This manual has been published in English and Spanish and a video version is presently being produced. To date, over 3,000 of the vacuum truck Recommended Practices have been distributed.

WJTA has also produced a medical alert card that is carried by many

StoneAge Sabertooth Dual Hose Reel

toneAge, Inc., has introduced the Sabertooth Dual Hose Reel for cleaning Slarge vertical tube bundles. Combined with the Banshee rotary blast nozzle, the Sabertooth is much easier, faster, and safer than hand lancing.

The operator controls the powered hose reel, which does the physical work. One man can clean two tubes faster than two men working manually. The Sabertooth eliminates the tangle of hose and back-breaking work of hose lifting and twisting and allows for high-pressure cleaning both going down and back up.

Page 14 WJTA on the web: www.wjta.org October 2008 Maxpro Technologies Now Offers Autofrettage Heavy Wall High Pressure Tubing

utofrettage is the process A of subjecting the internal bore of tubing to a pressure sufficiently high enough to plastically deform the bore, resulting in putting the inner wall into compression, providing a residual compressive stress once the pressure is released. Autofrettage produces improved fatigue life of the tube, important in production waterjet cutting applications, thus reducing down time. Maxpro’s stock of high pressure tubing, valves and fittings are available for fast shipment from inventory. With this new capability to autofrettage tubing, customers can continue to expect the high level of service and quick turnaround that Maxpro Technologies is known for.

onjet AB, a specialist in the design and C manufacture of remotely operated high- pressure waterjetting hydrodemolition machines, is expanding its headquarters manufacturing facilities at Haninge, 20km south of Sweden’s capital Stockholm. Conjet has committed investment capital of €1M for the building of these new facilities, which is in direct response to the continuing and growing worldwide demand for its products and services, ensuring that Conjet AB stays at the forefront of the world’s hydrodemolition equipment industry.

Conjet is extending its equipment assembly building to cope with the increasing business. The new extension will more than double the assembly area and houses a much larger parts stock holding section. “The new 1000m2 extension, which we started in March and expect to be complete by October 2008, is needed to cater for the increasing demand worldwide for our hydrodemolition equipment. The extra Conjet is investing €1M extending its headquarters manufacturing space will enable us to boost our capacity and facilities, which will boost capacity and reduce assembly times. considerably reduce our assembly times with the same number of employees and fulfil the needs of the future,” says Conjet AB President Carl Stromdahl.

Conjet currently offers an extensive range of remotely operated computer controlled hydrodemolition equipment, including a range of Robots and Jetframes together with tailor made hydrodemolition units, which can connect to Conjet Powerpacks or other high pressure water pumps. The company is currently working on several developments to further extend the The expansion will more than double the assembly area and is in product range. direct response to the continuing and growing worldwide demand for its hydrodemolition services and products, such as the latest For further information, visit www.conjet.com.
