Knowledge of concrete lateral pressure is critical for the economical and safe design of concrete formwork. Innovations in concrete mixtures and construction techniques are frequently implemented. As a result, frequent updating of the recommended theories in the ACI 347 standard for predicting the maximum lateral pressure has become necessary. Some important parameters, such as pore water pressure, cannot be fully represented in a small lab scale experiment. Thus, field studies on full scale placements are necessary. This paper reports on measurement methods used to collect data under field conditions in studies conducted by this researcher and others. The objective of the paper is to present the experimental approaches for the benefit of other researchers contemplating similar research.
