In what order should sand, cement, crushed stone, water be poured into a concrete mixer
Concrete is an artificially created stone, the building material that is in demand not only among professional builders, but also in private households. Concrete is used for flooring, foundations, walls, and ceilings. The process of preparing a solution for some is not an easy task.
If you need to prepare a small amount of solution, then a deep trough, a shovel, a hoe and a bucket will do.
The most important thing is to mix all the ingredients thoroughly. A concrete mixer helps to facilitate the process and make a high-quality mortar, if used correctly.
First you need to prepare everything in advance and choose fillers. Somewhere you will need crushed stone, gravel, expanded clay, volcanic tuff, perlite, etc. The most commonly used is crushed stone. Cement brands are also different (M100-300, etc.). The higher the number, the more sand you need.
It would seem that what difference does it make how to knead the solution - I filled everything up, poured water and just stir it.
The catch lies in the details. There are certain instructions, sequence, proportions and experience.
What happens if you pour sand and cement into a concrete mixer, and then just add crushed stone and water? There will be an uneven distribution along the walls and in some places everything will stick. You will have to pour excess water, the solution will turn out to be liquid.
Concrete batching sequence
The concrete mixer should be tilted at an angle of 45 degrees. First comes the right amount of water. Many people use a regular bucket as a measuring container. It is better not to fill in all the water at once in one go. Let's say we pour 10 liters, and then another one. If the solution is thick, you can always add water.
Turn on the device and pour 2 buckets of rubble. Then cement (one thing 12 liter bucket). And after that we pour more rubble bucket. The crushed stone will distribute the cement over the entire surface of the mixer. It acts as an abrasive, cleaning the walls of the unit. The mass is uniform.
Sand comes last. For the specified amount of crushed stone, cement, we fill 3 buckets of sand. If you need more water, you can add.
Proportions for 50 liters. concrete are as follows: 1 bucket of M400 cement, 3 buckets of sand and rubble. Water will need about 11 liters.
Only with such a sequence will the quality of the solution be ideal, homogeneous. Moreover, the outside walls of the concrete mixer will always be clean.
