Why pile chipping is required before the pile cap works

Piles were cast with high slump concrete, during the concreting of piles, there is a chance that fines from concrete might accumulate at the top and also if there i slush in the bored pile, it will also come up during concreting. So the concreting of the pile is overflowed to take out all impurities.

What Is Self Compact Concrete | Equipment V-Funnel Test

This test was developed in Japan. The equipment consists of a V-shaped funnel shown in the above figure. • The V- Funnel test is used to determine the filling ability (flowability) of the concrete with a maximum size of aggregate 20 mm size. • The funnel is filled with about 12 liters of concrete.Find the time taken for it to flow down.

When column loads are heavy, as in high-rise buildings for example, large piles or groups of piles are usually required to carry the loads down to a competent stratum. Bored piles, also referred to as auger-cast piles, are large-diameter, cast-in-place concrete piles, usually lightly reinforced by steel reinforcing bars (0.5%) under gravity loads.

Guide To Concrete Workability | Concrete Slump | Concrete2you

Concrete workability. One of the basic attributes of any concrete is its workability or "consistence", that is, how easy it is to push one way, pull the other, and float to a smooth level surface. Workability is largely determined by how fluid the concrete is. This is referred to as "Slump". Essentially, the more fluid the concrete, the higher

Slump Slump is the measure of concrete consistency; the higher the slump, the wetter the concrete and the easier it flows. Slump is measured in accordance with ASTM C143 (ASTM, 1998) by inverting a standard 12-inch-high metal cone, filling it with concrete, and then removing the cone; the amount the concrete settles in units of inches is the slump.
