The Slump is performed according to the procedures mentioned in the ASTM C143 standard in the United States, IS 1199 - 1959 in India, and EN 12350-2 in Europe.. Generally, the value of the concrete loss is used to find workability, which indicates the water-cement ratio, but there are several factors, including material properties, mixing methods, dosing, additives, etc. . What are the differences between shear slump and collapse slump in Most people in the business agree that a typical slump for ordinary decorative concrete applications would be in the 4- to 5-inch range, but there's no hard-and-fast rule. Slump test shows an indication of the uniformity of concrete in different batches.The shape of the concrete slumps shows the information on the workability and quality of concrete.
