Determination of the normal consistency of hydraulic cement
Take a measured quantity of powdered cement and record its weight as M 1. Add a weighed amount of water (M 2) to the cement and thoroughly mix to make a paste out of it. Take an ample quantity of the cement paste in your hands and make a ball out of it. Toss the cement ball between two hands, spaced approximately 150mm from each other, six times.

How to Make Large Concrete Garden Balls
To make large concrete garden balls, you'll need several bags of ready-mixed concrete, a bucket to mix the concrete in, and a large round mold, such as an inflatable beach ball or an old tire. You'll also need some sort of reinforcement material to give the ball strength and durability (such as wire mesh, rebar, burlap strips, etc.).

Kelly Ball Test: The Definitive Guide
The Kelly Ball Test is conducted using a metal ball with a diameter of 150 mm and weighing 13.6 kg. The ball is placed on a fresh concrete surface and allowed to settle for a set amount of time, typically 15 seconds. The depth of the indentation left by the ball is then measured using a ruler or depth gauge.

What Causes Cement Balls?
Cement has a high affinity for water. So upon contact with water, the dry cement powder acts like a sponge and globs up. The balls form as these globs roll against the inside drum surface. The key to prevention is to program a material-loading sequence that deposits the cement and the coarse aggregate into the drum at the same time.
