Technology Name: Liquid Nitrogen-Cooled Diamond-Wire Concrete Cutting

Demonstration Name:10-ft high and 3-ft thick concrete walls | Demonstrated on: 3/1/1998
Demonstration Site: Hanford C-Reactor

Demo Objective

• No cooling water required therefore, no secondary liquid waste is generated • Cuts quicker and more precise than baseline concrete saw • Cuts thicker concrete thereby, eliminating the need for multiple setups and cuts • Improved ease of setup and operator safety.

Demo Results

Technology can be use to cut almost any concrete structure and because it uses liquid nitrogen instead of water, it reduces secondary waste generation. However, dust control is required. It is quick to install and can be operated remotely. This technology produces smooth cut. Thew shortfalls of this technologies are the following: Dust control may require an atmospheric enclosure Cutting rate is slower than with a water-cooled wire, and the area of cut is limited Diamond wire shows increased wear compared to baseline diamond wire.
