Solving for Why
A Janney Technical Center Video Series
SOLVING FOR WHY: Vacuum Chamber Glass Test
WJE instrumentation specialist Roger Pelletier demonstrates a vacuum chamber test: loading a glass window to failure to determine whether noted surface conditions significantly affected the glass's structural integrity.
SOLVING FOR WHY: Atomic Absorption Spectroscopy
WJE chemist Tonya Werner demonstrates the use of our atomic absorption instrument to identify the concentration of different elements in a mortar sample.
SOLVING FOR WHY: Monotonic tension test
WJE structural engineer Scott Graham demonstrates a monotonic tension test—pulling rebar apart until it breaks—using our Tinius Olsen test machine.
solving for why: metallographic examination
WJE metallurgist Al Stone discusses metallurgical evaluation—common samples, how we identify issues, and how this information helps our clients.
SOLVING FOR WHY: Evaluating Water-to-Cement Ratio
Solving for why: ACCELERATED WEATHERING TO TEST STONE DURABILITY
WJE architect Daren Kneezel explains the process by which we test the durability of dimension stone cladding.
SOLVING FOR WHY: MATERIAL IDENTIFICATION USING FTIR
WJE chemist Kim Steiner walks through one method used to identify materials.
