A few small questions about concrete
Thread Content
As the title suggests, I came across the terms \"amount of concrete poured\" and \"slump\" today, and I would like to ask everyone for their advice.
The number of vibrations should refer to the number of times the vibration rod is inserted into the concrete during pouring. Slump is a parameter used to measure the workability of concrete, ensuring that it is not too dry or too wet when placed in the formwork. Typically, concrete is compacted in a slump bucket made of metal and placed on a horizontal surface (with an upper diameter of 100 MM, a lower diameter of 200 MM, and a height of 300 MM); after that, the metal bucket is removed and the height of the concrete slump is measured.
Slump refers to the workability of concrete; more specifically, it is what ensures the smooth progress of construction. This includes the water retention, fluidity, and cohesion of concrete. The factors that affect concrete slump include variations in the gradation, water content, measurement errors with the measuring equipment, the amount of admixtures used, as well as the temperature of the cement – a factor that is often overlooked. Workability refers to the ability of concrete to be easily worked with and to achieve a uniform and dense structure; it is a comprehensive property that includes fluidity, cohesiveness, and water retention. The factors affecting workability mainly include the amount of water used, the water-cement ratio, the sand ratio, as well as aspects such as the type of cement, aggregate conditions, time and temperature, and admixtures.
Let’s learn* it a bit; thanks for the explanation from above
The result of the slump test is simply the value measured with a ruler; during the test, the number of vibrations required is specified, and it is not allowed to have either more or fewer vibrations
