Significance and Use of ASTM C143 Slump is a measure of the consistency of a sample of concrete, and tells you how fluid the concrete will be. It can help give an idea of workability, telling you how easy or hard it will be to place, and can help to predict strength.

The ASTM Standard Specification for Portland Cement (ASTM C150) provides for five types as follows: - Type I—The standard product that has long been in use with no limitation on the proportions of the major oxides (CaO, SiO2, Al2O3, Fe2O3), also referred to as “ordinary portland cement.”

Summary of Test Method The mold is raised, and the concrete allowed to subside. The vertical distance between the original and displaced position of the center of the top surface of the concrete is measured and reported as the slump of the concrete.

ASTM C 184-94 PDF | Fineness Test Of Hydraulic Cement By Sieves | Material Testing.

The fineness of cement can be determined by Sieve Test or Air Permeability test. Sieve Test: Air-set lumps are broken, and the cement is sieved continuously in a circular and vertical motion for a period of 15 minutes. The residue left on the sieve is weighed, and it should not exceed 10% for ordinary cement.

Measure slump from the top of the mold to the displaced original center of the concrete. Record results to the nearest 1/4-inch. Begin and complete slump test within 2-1/2 minutes, maximum.

The procedure for conducting chemical tests of hydraulic cement is covered in IS: 4032-1985*. (/irst revision). 2.1 The samples of the cement shall be taken in ance with the requirements of IS: 3535- 1986* and the relevant standard specification for the type of cement being tested.
