Effects of Construction Joint in Mass Flowable Concrete
Publication: Journal of Materials in Civil Engineering
Volume 10, Issue 1
Abstract
Flowable concrete is used for the basemat of Kawasaki Manmade Island, because only superplasticized concrete can meet the stringent performance requirements of this project. Due to the large volume of concrete required, construction joints are bound to occur. To assist in the development of an ultimate concrete placing cycle for the basemat, a series of tests has been conducted to evaluate the possible effects of construction joints in this mass flowable concrete. The general procedure for these tests is designed to simulate the worst real condition that could be encountered in the field. Simulation of construction joints is achieved by creating an artificial joint in each of the concrete test samples. Compressive strength and concrete flowing capability are used as the main criteria. The key data generated and observations made during the evaluation are presented. Conclusions and recommendations regarding placement of mass flowable concrete are given.
