Compaction Factor Test – Workability of Concrete

Compaction Factor Test is designed in such a way that it can be used only in laboratory but in some cases, it can be used for field concrete tests. The compacting factor test has been developed at the Road Research Laboratory in United Kingdom. This test is one of the most accurate test performed in order to determine the workability of concrete.

The apparatus of compaction factor test is shown below.

COMPACTING FACTOR TEST APPARATUS

Mega Structure 6 - Akashi Kaikyo Bridge

Akashi Kaikyō Bridge, also called “Pearl Bridge”, is located in Japan and considered as Japan’s finest engineering feat. Akashi Kaikyō Bridge is the world’s longest suspension bridge in the world with a length of 3911 meters (12,831 ft). The Akashi Kaikyō Bridge serves as a link between the city of Kobe and Iwaya by crossing the Akashi strait. The construction was finished in a span of 12 years which actually begin in the year 1986 and completed in the year 1998. The bridge plays an important role in providing three routes across the inland sea.
