RES2013-39: Development of Class P-SCC (Self-Consolidating Concrete) and Class
A-SCC Concrete Mixtures |
摘要: |
Self-consolidating concrete, also known as self-compacting concrete (SCC), is a highly flowable concrete that spreads into
place and fills formwork without the need for mechanical vibration. SCC reduces the time and labor costs needed for concrete
placement. This project was proposed by the Tennessee Department of Transportation (TDOT) and carried out by The
University of Tennessee at Chattanooga (UTC). The aim of the proposed project was to develop four new SCC mixtures (two
Class P-SCC and two Class A-SCC), and ensured they met the minimum strength and durability requirements for TDOT
Class P and Class A mixtures. The proposed research program ensured that desired fresh properties are achievable with
materials available in Tennessee. With the approval of TDOT management, Class P-SCC and Class A-SCC (with specified
fresh and hardened properties) would appear as options in TDOT specifications. Four groups of mixtures were prepared, two
of them were used to develop Class P-SCC mixtures and the other two were used to develop Class A-SCC mixtures. Each
group consisted of twelve mixtures. The mixtures were subjected to testing to assess their fresh and hardened properties.
Finally, the results of this study were evaluated to recommend performance specifications for Class P-SCC and Class A-SCC
for TDOT adoption of SCC standard operating procedures. |
