RESEARCHES CARRIED ON BY THE ENGINEERING
EXPERIMENT STATION
AND THE ENGINEERING SCHOOLS AND
DEPARTMENTS
July 1, 1938, to June 30, 1939
Engineering researches of value to industry are carried on by the Engineering Experiment Station, by the several schools and departments, and by engineering undergraduate and graduate students.
I. Researches of the Engineering Experiment Station include:
(a) Station researches
(b) Co-operative researches — direct with the industry
(c) Co-operative researches — through the Purdue Research Foundation.
II. Researches of the schools and departments include:
(a) Staff researches
(b) Graduate researches
(c) Undergraduate researches.
The report that follows includes brief reports on all active research investigations carried on by the Engineering Experiment Station and by the several engineering schools and departments of Purdue University for the period of July 1, 1938, to June 30, 1939. The reports are grouped under the several divisions of the Engineering Experiment Station which correspond to the teaching divisions of the schools and departments of engineering.

Hollow Glass Block Research (Project C-29). Co-operative research for the Owens-Illinois Glass Company, started July, 1935. Investigators, R. B. Crepps and R. E. Mills.
Purpose. To study the physical and mechanical properties of hollow glass blocks as individual units and also when used for masonry walls.
Progress Report. Report No. 8, consisting of 37 pages, was submitted on:
(1) Elasticity of an Insulux glass block panel.
(2) Analysis of the panel under high humidity conditions.
(3) Influence of capping on compressive strength shown by Insulux glass block.
(4) Shear test for the different mortar-bearing surfaces.
(5) Compressive strength of blocks taken from stock with Hydrocal capping aged in air for 3 hours.
(6) Similar tests of blocks with special grooves on mortar-bearing surfaces.
(7) Similar tests on Oberlin College blocks.
A 40" x 54" drying cabinet for small wall panels of glass blocks used in conjunction with the Wallette permeability tank was completed, and six panels have been tested for permeability under conditions which approximate driving rain. A great deal of data has been obtained, but no results have been reported.
A new study of mortars in relation to glass block construction has been initiated, which will cover an extended period because of the development of new testing methods.
A vapor pressure apparatus was designed to study them travel of moisture through masonry mortars due to vapor pressure created by temperature differences.
A special report has been made on shear and tension tests of block specimens with special surface-coating materials.
These studies for the Owens-Illinois Glass Company are being continued, and a special investigation of masonry mortars is being carried on as a co-operative project between the company and the University.
