The Center for Big Bend Studies at Sul Ross State University has been awarded a grant for $12,500 from the Cooperative Research and Training Programs of the National Park System, Department of the Interior, a press release detailed.
David W. Keller, a senior project archaeologist with CBBS, wrote the proposal to “source, sample, analyze and test historic adobes and local clay rich soils for use in projects at Fort Davis National Historic Site.”
The grant will fund the project in three phases.
>> First, a range of samples will be collected and field tested or sent to a lab for analysis of grain size and mineral makeup.
>> Second, adobe bricks will be made and tested for strength and durability, and then used to create plaster swatches which will be examined for adhesion, cracking and abrasion resistance.
>> Third, the best batches will be utilized for experiments, including jet tests to determine erosion resistance.
“By employing a rigorous methodology, detailed record keeping and fully reporting on results, it is hoped that this project can guide maintenance for years to come, and possibly assist other national parks in their own earthen historic preservation programs,” Keller wrote in the proposal.
He said he expects to start the testing phase in about a month. While Keller said the project extends through February 2023, he believes it will be complete by the end of this year.
