Hibernia: An Irish Immigrant Neighborhood in Burlington, Iowa, 2000

Hibernia is mostly a memory today as is so many immigrant neighborhoods. However, there are several guideposts to the past that still witness to the history of years gone by, such as St. Patrick's Church, a beacon reflecting the Irish Catholic heritage. Murray Iron Works and the Embalming Burial Case Company and the worker's homes on the surrounding streets witness to the industrial/employee relationship of the past.

Evaluation of Mini Slump Cone Test, MLR-97-01, 2000

Early stiffening of cement has been noted as contributing to workability problems with concrete placed in the field. Early stiffening, normally attributed to cements whose gypsum is reduced to hemi⋅hydrate or anhydrate because of high finish mill temperatures, is referred to as false setting. Stiffening attributed to uncontrolled reaction of C3A is referred to as flash set. False setting may be overcame by extended mix period, while flash setting is usually more serious and workability is usually diminished with extended mixing. ASTM C 359 has been used to detect early stiffening with mixed results. The mini slump cone test was developed by Construction Technology Laboratories (CTL), Inc., as an alternative method of determining early stiffening. This research examined the mini slump cone test procedure to determine the repeatability of the results obtained from two different testing procedures, effect of w/c ratio, lifting rate of the cone, and accuracy of the test using a standard sample.
