TEST FOR WORKABILITY OF CONCRETE - SLUMP CONE
UltraTech Cement・3 minutes read
Concrete workability is assessed through the slump test, which determines the type of slump and guides adjustments to the mix for optimal results. Proper execution of the test is essential to achieving the desired concrete slump and ensuring the project's success.
Insights
- The workability of concrete is assessed through the slump test, which involves a cone-shaped mold, tamping rod, and specific steps to measure the subsidence after removing the mold, with adjustments to water content and aggregate sizes being crucial based on the slump results.
- Different types of slumps, such as true, shear, or collapse, exist, with true slump being the ideal form. Conducting the slump test accurately and adjusting the mix proportions accordingly are essential for achieving the desired workability of concrete.

"Concrete workability determined by slump test"
- Workability of concrete is determined by the slump test, a simple procedure involving a metallic mold shaped like a cone, a tamping rod, and specific steps like filling the mold in layers, tamping each layer evenly, and measuring the subsidence after removing the mold.
- The slump of concrete can be true, shear, or collapse, with true slump being the preferred form. Adjustments to the mix, especially water content, may be needed based on the slump results, and altering aggregate sizes can also impact workability. It is crucial to conduct the slump test correctly, aiming for the desired slump type and adjusting proportions accordingly.
