This is a summary of the video transcript:
The video is a guide on how to make concrete plates for barbells or dumbbells using sand concrete, which is a ready-made mixture of cement, sand and small crushed stone. The video shows how to make formwork, bushings, and pancakes of different weights and diameters using a table that the author prepared. The video also gives some tips on how to avoid cracks, chipping, and distortion of the pancakes and how to adjust their weight and smoothness. The video compares the sand-concrete pancakes with the reinforced concrete ones that the author made earlier. The video ends with a call to subscribe, rate and watch new releases.
Here are some key facts extracted from the text:
1. The text is a guide on making concrete plates for barbells or dumbbells.
2. The author uses sand concrete instead of regular concrete because it is ready-made and only requires water.
3. The author provides a table to find the diameter and height of the pancakes based on the desired weight and the density of the material.
4. The author avoids welding and uses a pipe with an internal diameter of 16 millimeters for the bushings.
5. The author adjusts the weight of the pancakes by sanding them after they have gained strength.
6. The author gives several tips on how to make the formwork, the bushings, the concrete mixture, and the compaction.
