Project Objective

To develop quality control methods for high performance concrete.

Project Abstract

Developments in structural design together with the increasing need for faster and accelerated construction schedules require that the transportation engineer determine the actual strength of the in-place concrete rather than relying on indications of potential strengths from traditional quality control test specimens. As structural demands increase (taller structures, longer spans, smaller members, and/or faster construction), the demands to better evaluate the material performance also increases. Further, as more efficient materials are optimized, the realization of full strength potential of the concrete becomes more dependent on curing, placement conditions such as temperature rise, moisture conditions, and member dimensions. The discrepancy between traditional quality control specimens and in-place concrete is in fact magnified for high performance concrete or concrete subjected to high temperatures during hydration of the cementitious materials. To date, no study has fully investigated the level of heat generated during hydration where match-curing technology becomes necessary to adequately estimate the mechanical properties of the concrete both at early and later-ages.

Task Description

The tasks for this project include (i) a state of the art literature search, (ii) a mixture proportioning development phase, (iii) a laboratory testing phase involving different mixture proportions and SA/V ratios, and (iv) a reporting phase including technical memos of the testing program and progress reports, a technical seminar for technology transfer to industry, and a final technical report.

Anticipated Benefits

Enhanced QC/QA measures for precast/prestressed HPC members and a better understanding of the influence of SA/V on the QC of HPC.
