Water Repellent, Silica Fume Modified Shotcrete with Micro Fibers View Item For over a century, The Euclid Chemical Company has served the global building market as a worldwide quality supplier of specialty products and technical support services for the concrete and masonry construction industry. Dry-mix shotcrete is a highly efficient and cost-effective way to apply concrete or mortar, for both new construction and repair. Properly applied, it's structurally sound and durable. But it requires specialized knowledge, skill and experience. It's not a job for just any contractor.

The Aliva AL-252.1 has a long tradition as the workhorse of the heavy construction industry. With an output ranging from 3.5 to 11 m³/hour (4.6 to 14.4 yd³/hour), the Aliva AL-252.1 is ideally suited for high volume, dry-process shotcrete operations. This machine is commonly used as a stand alone unit, or can be integrated into bulk-type shotcrete systems when installed on mobile equipment and fed by a bulk hopper.

1. HISTORY

The Aliva-252 is a sturdily constructed two-axle concrete spraying machine for the processing of dry mix.

2. APPLICATION

The machine can be used thanks to its compact design and mobility where space is at a premium e.g. in mines and galleries. Other potential applications are slope and hillside protection, lining of water tanks and swimming pools, guniting for single and double shell tunnel construction, backfilling of tubbings.

The Aliva-252 is available in the following versions:

• BASIC

Electric drive, combined with BASIC-Dosing unit (not synchronized)

• AIR

With air drive, combined with BASIC-Dosing unit (not synchronized)

*** Air consumption data are approximate values and are depending on conveying output, conveying distance and hose diameter.

Caution: For the configuration AIR (with air motor) it has to be considered:

Total air consumption = Air consumption for conveying + Air consumption for air motor! 1 Nm³/min = 35 cfm
