Title: Simple Analytical Model for Formwork Design of Self-Consolidating Concrete

Abstract:Self-consolidating concrete (SCC) is a recently developed innovative construction material. No additional compacting is needed because of its high filling ability; consequently, the labor cost of compacting is economical. SCC, however, needs a stronger formwork that can resist the higher lateral pressure of cases that use ordinary concrete. This study uses the proposed two-function model to: 1) characterize the pressure response of a fresh SCC mixture; and 2) evaluate the maximum pressure that develops on the formwork. Various SCC compositions were experimented with to show the validity of the evaluation. The experimental results and analytical interpretation suggest that the maximum lateral pressure allowed in the design of the SCC formwork could be determined from two parameters that depend on the placement rate and the duration of the placement.
