dc.descriptionTechnical Report-
dc.description.abstractThe Engineer Research and Development Center, Geotechnical and Structures Lab (ERDC-GSL) has used Fort Polk as a large-scale testing site for many years. Many cementitious materials have been developed for design validation testing. These cementitious materials, their constituents, and their mechanical properties often went undocumented, making it difficult for researchers to replicate or draw comparison from previous testing. This report aims to begin a process of detailed cementitious material re-ports for all research efforts in the region. The objective of this report is to document the development of a field castable 6 ksi sanded grout mixture and a 7 ksi sanded grout mixture used in experimental testing programs at Fort Polk in January 2014 and February 2015. GSL required the development of a 6 ksi and 7 ksi mixture for testing scaled bridge columns. The reduced scaling of the test members resulted in very small rebar spacing. These designs lead to the development of very flowable specialized grouts. This report details the development of this specialized grout for the pur-pose of aiding future cementitious mixture developments in the region. These results are applicable to efforts where reduced scaling reduces the spacing between scaled reinforcing where all aggregates in the concrete mix would not fit between reinforcing.en_US
