Guidelines for design, testing, production and construction of semi-flowable SCC for slip-form paving

Abstract

A new type of self-consolidating concrete (SCC), semi-flowable SCC (SFSCC), has been developed for slip-form paving construction. Several field applications of the SFSCC have been conducted. Based on the research results, guidelines for SFSCC mix design, testing, production and construction are developed. This paper provides an overview of the guidelines. In this paper, SFSCC mix design methodology, quality control test methods and special requirements for paving equipment and operations as well as post-placement techniques are presented.

Keywords:
