The slump of concrete (also known as slump or fluidity) refers to the fluidity and plasticity of concrete under the action of its own gravity and vibrating force.
Slump is determined by measuring how much concrete plant collapses freely after the force is removed. A conical mold is usually used to fill it with concrete under certain conditions, then the mold is removed, and the slump height of the concrete is measured to obtain the slump value. The unit of slump is millimeter (mm).
The impact of slump on the project is as follows:
1. Pouring performance: The level of slump directly affects the pouring performance of concrete. A higher slump can make the concrete flow more easily and fill the mold, which is beneficial to the construction personnel to operate and pour the concrete better.
2. Firmness: Slump is closely related to the water content of concrete and the amount of cementitious materials. Proper slump can make the concrete better filled in the mold, thereby improving the compactness and firmness of the concrete.
3. Design requirements: Different construction projects may have different requirements on the slump of concrete. For example, a building floor may require a small slump for flatness, while a column or wall pour may require a high slump for filling a confined space.
4. Construction schedule: Too high or too low slump may have a negative impact on the construction schedule. High slump can lead to loss of concrete and uncontrollable stretching, while low slump can lead to slower construction due to the difficulty of concrete flowing and filling.
5. Quality control: By controlling the slump, the quality of concrete can be better controlled. Appropriate slump can ensure that the concrete meets the design requirements during the pouring process, thereby reducing the occurrence of defects and quality problems.
In short, slump is an important indicator of concrete performance, which directly affects the construction performance, structural strength and final engineering quality of concrete. During construction, through reasonable detection and control of slump, the quality and performance of concrete can be guaranteed to meet the design requirements.
