3. Test method for thickened concrete slump cylinder
() Wet the slump cylinder and the bottom plate, and apply water to the inner wall of the slump cylinder and There should be no open water on the floor. The base plate should be placed on a solid horizontal surface, and the cylinder should be placed in the center of the base plate, and then step on the footboards on both sides with your feet. The slump cylinder should remain in a fixed position when loading.
() Put the mixed concrete samples into the cylinder evenly in three layers, so that the height of each layer after compaction is about the height of the cylinder. Each layer should be tamped with a tamping rod once. The tamping should be carried out from the outside to the center in the spiral direction. Each tamping should be evenly distributed on the cross section. When inserting concrete on the side of the tamping drum, the tamping rod can be tilted slightly. When tamping the bottom layer, the tamping rod should penetrate the entire depth. When tamping the second and top layers, the tamping rod should penetrate this layer to the surface of the next layer. When pouring the top layer, the concrete should be poured up to the top of the barrel. During the tamping process, if the concrete sinks below the barrel mouth, it should be added at any time. After the top layer is tamped, scrape off excess concrete and smooth it out with a trowel.
() After clearing the concrete on the bottom plate of the cylinder side, lift the slump cylinder vertically and smoothly. The lifting process of the slump cylinder should be completed within ~. The entire process from the beginning of loading to lifting the slump cylinder should be carried out without interruption and should be completed within 1 hour.
() After lifting the slump cylinder, measure the height difference between the height of the cylinder and the highest point of the concrete specimen after the collapse, which is the slump value of the concrete mixture. After the slump cylinder is lifted, such as If the concrete collapses or one side is sheared, the sample should be resampled and measured separately. If the above phenomenon still occurs in the second test, it means that the concrete has poor workability and should be recorded for future reference.
() While measuring the slump, the following properties of the concrete mixture can be evaluated visually and recorded for future reference.
