A V shaped funnel is filled with fresh concrete and the time taken for the concrete to flow out of the funnel is measured and recorded as the V-funnel flow time [10-12].
The first step is to prepare the cone and base plate then place the cleaned base in a stable leveled position, fill the cone without any agitation or Roding, and strike off surplus from the top of the cone.
Allow the filled cone to stand for not more than 30s; during this time remove any spilled concrete from the base plate and ensure the base plate is damp all over but without any surplus water (Figure 2).
In this study the area has been covered is making the design mix of self-compacted concrete and it’s performance – economic comparisons with prevailing conventional grade of concrete of M-40 grade.
Self-compacting concrete (SCC) was first developed in Japan, in the early nineties of the previous century, under the stimulating leadership of Prof. The main idea behind self-compacting concrete was, that such a concrete is robust and relatively insensitive to bad workmanship.
The three bar test simulates more congested reinforcement [13-15].
The main concept of this test is to allow a measured volume of fresh concrete to flow horizontally through the gaps between vertical, smooth reinforcing bars and the height of the concrete beyond the reinforcement is measured.The V-funnel shall be made from metal; the surfaces shall be smooth, and not be readily attacked by cement paste or be liable to rusting.However container is needed to hold the test sample and having a volume larger than the volume of the funnel and not less than 12 L (Figure 3).
