Slump test and compaction factor test
WebbWhat Is Slump Cone Test? A Slump cone test or concrete Slump test is to determine the workability or consistency of the concrete mixture prepared in the laboratory or at the construction site during the course of work. ... Compaction Factor Slump (mm) Very Low: 0.78: 0 – 25: Low: 0.85: 25 – 50: Medium: 0.92: 50 – 100: High: 0.95: 100 – 175: WebbOn 18 August 2016, I and my group, F2, had carried out building workshop practical 1, which is the slump test and compaction factor test. Based on my notes, I learnt that slump test is carry out to determine the effect of slump on different water/cement ratio and concrete mix while the compacting factor test is carried out to determine the workability …

WebbFor concrete with limited workability and for which the slump test is ineffective, the compaction factor test is used. It is accurate for medium to low workability, such as 0 to 0, and it is not suitable for workability less than 0. From results and analysis, the slump value for sample number 1, 2, 3 and 4 are 0, 0, 0 and 0 respectively ... Webb28 okt. 2014 · Generally we specify workability of concrete in terms of its slump test value. But sometimes it is also specified by another test called compaction factor. The relation between slump and compaction factor is roughly as follows. Relation Between Slump & Compaction factor Share this: Email Print More
WebbOn the second lab practical we make the Compaction Factor Test and Slump Test to determine the work-ability of concrete and determine the effect of slump on different water/cement ratio and concrete mix. Same on the cube test, we need to measure the mass of cement, sand and aggregate by ratio 1:2:4 and mixed it. WebbIt was found that the slump and compaction factor values of the concrete mix with Mogadishu manufactured sand decreased compared to that of conventional concrete.
Webb7 juli 2024 · The slump test does not give accurate results for low worability of concrete when slump is<50mm. The compaction factor test is a workability test for concrete conducted in the laboratory. It was developed by the Road Research Laboratory in the United Kingdom and is used to determine the workability of concrete. The compaction … WebbThe property of concrete which determines the amount of useful internal work, necessary to produce full compaction i.e workability is the amount of energy to...
