Sulfur concrete is a Distinctive concrete that works by using sulfur like a binder and does not involve cement or drinking water.
Workability might be calculated via the concrete slump take a look at, an easy measure from the plasticity of a refreshing batch of concrete following the ASTM C 143 or EN 12350-two examination specifications. Slump is Usually measured by filling an "Abrams cone" using a sample from a contemporary batch of concrete. The cone is positioned Using the wide close down onto a amount, non-absorptive surface area. It is then loaded in 3 layers of equivalent quantity, with Every single layer getting tamped with a metal rod to consolidate the layer.
