Components

Pay attention to the following elements when studying the proportions and recipe for paving slab mortar:

1. Cement mixture.
2. Sand.
3. Crushed stone.
4. Additives-plasticizers.
5. Liquid.

The master does not need to use specialized equipment for stirring because self-production eliminates the need to prepare large volumes of the mixture. This task is well-suited for an electric mixer.

It’s crucial to follow these guidelines when combining the concrete mixture:

1. Correct calculation of the ratio of additives.
2. Taking into account the quality of raw materials when choosing.
3. Maintaining a water-cement ratio within 0.4.
4. Using a vibrating table for forming pouring.
5. Surface painting.

Cement

High-quality cement preparation is required to enhance the paving slabs’ performance characteristics and quality indicators. Using materials containing additives is not feasible for the implementation of such a project.

1. The binding properties of the mixture must be 15-22 when the raw material reacts with water.
2. Plastic parameters must decrease after 45 hours from the start of hardening.
3. Complete hardening should take no more than 7-12 hours, and the set of strength properties by 70% – no more than a week at normal temperature.

Water

Because of the way the paving slab mixture is made, a lot of water can be added to mix the concrete in buckets or other containers. The final product’s quality is dictated by the water-cement ratio, which impacts the following concrete consistency parameters:

1. Degree of resistance to frost and moisture.
2. Porosity and stratification.
3. Formation of cracks and duration of hydration.

The ideal W/C values, if you mix the solution yourself, should be 0.4.

Due to its high rigidity and poor workability, plasticizers are added to further dilute the composition. Store-bought additives or homemade remedies, such as adding a tablespoon of detergent to each batch of concrete mixer, can serve as these.

Sand and crushed stone (gravel)

Crushed stone and sand are added to the mixture when laying paving slabs. The following issues are resolved by these parts:

1. Reduce the cost of the final product.
2. Increase the strength properties and wear resistance of the tile.
3. Improve water resistance and resistance to negative temperatures.

The concrete mixture takes on the characteristics of granite, gravel, or dolomite when sand and crushed stone of the right kind are added, giving the finished product the required shape and size. The following specifications should serve as your guide when selecting fillers:

1. Crushed stone and sand containing a large amount of clay cannot be used.
2. Preference should be given to fine crushed stone and coarse sand.
3. Granite screenings have the highest strength and frost-resistant properties.
4. Torn particles of quarry sand are characterized by high adhesion.
5. To reduce the intensity of delamination, it is recommended to use continuous filler containing pebbles of different sizes.
6. Due to the compact dimensions of the tiles, it is better to choose crushed stone 5/10.

Sealants

Paving slab concrete is composed in a way that allows for the inclusion of sealing agents, which enhance the product’s strength and resistance to the following weather conditions:

Additionally, sealants solve the issue of tile abrasion on the decorative layer. Gravel screenings or crushed granite stone fulfill this role as additives. While crushed stone is in high demand due to its geometrically broken shape and increased density, the density indicators of the two components are nearly identical. But because river or sea gravel is rounded, there is less binder coverage area.

Some untrustworthy suppliers use inexpensive expanded clay in place of crushed stone. These additives deteriorate the future tile’s parameters and increase its susceptibility to adverse effects.

It is preferable to use large-fraction crushed stone (20–40 mm) to dilute the composition. It is advised to stop using gravel at screenings or a small-fraction component that has been previously sifted through a mesh.

Additives

It’s crucial to account for the inclusion of additives when formulating a solution for paving slabs.

1. Plasticizers. They are intended to improve the strength and properties of the final product.
2. Hardeners. Help speed up the hardening process of concrete.
3. Dyes.

Plasticizer

Numerous plasticizers exist, each with unique benefits and characteristics.

1. Dry mixes from foreign brands. Used for small production volumes and ambient temperatures not lower than -2°C.
2. Liquid plasticizers. They differ in different modifications: there are options for hot conditions of use or for products resistant to severe frosts.

You can use two different types of plasticizers when making cement for paving slabs, as they increase the solution’s strength properties by fifteen to twenty percent. Additionally, there is an improvement in water and frost resistance, and the cement mixture’s overall cost is lowered by 18–20%.

Hardener

Although hardeners are justified in the winter, they can also be used effectively in the summer. By using these reagents, the tile can harden more quickly, lowering the possibility that it will distort while drying. The process of making tiles is accelerated by additives as well.

Coloring pigment

You must consider the coloring pigment when determining how to make a solution for paving stones. Dry powder paint is typically used just as is, as it has a neutral reaction and has no effect on the final product’s quality.

You might be surprised to learn how easy it is to make the ideal mortar at home for paving slabs. You don’t need specific tools or experience to mix and lay long-lasting, expert-quality mortar; all you need are a few common materials and simple instructions. This tutorial will take you step-by-step through the entire process, from selecting the appropriate materials to reaching the desired consistency and using mortar for a perfect finish. Whether you’re building a new patio or remodeling your driveway, you’ll have all the knowledge you need to complete the project quickly and skillfully.

Proportions for vibration casting

The following ratio of additives is taken into consideration when determining the proportions of the vibration casting solution:

1. M250 / B20 – a bucket of cement, 2 buckets of sand and 3.5 buckets of crushed stone.
2. M300 / B22.5 – a bucket of cement mixture, 1.7 buckets of sand and 3.2 buckets of crushed stone.
3. M400 / I30 – a bucket of cement mixture, a similar amount of sand and 2.5 buckets of crushed stone.

For vibration casting, homemade sand concrete can be utilized in addition to factory cements. Sand and cement are combined in one-third of the recipe for concrete. The weight of the finished product determines the volumes of the liquid and dry mixture.

For gray tiles

The following elements need to be considered when coming up with a plan to install gray tiles in Moscow:

1. Region of use. The resistance of figured products to negative temperatures depends on this nuance.
2. Soil and climate conditions. If the region has high GWL values, frequent precipitation or high humidity, it will be necessary to reduce the W/C ratio and add additives to the paving slab solution that improve water resistance.
3. Production technology. If the vibration casting method is used, the paving slab surface will be even and smooth. Coarse sand is used to add roughness.

If a specialized deep vibrator is employed in the building of monolithic structures, then the technique of bayoneting inside the formwork with a vibrating table can be applied when laying tiles in rural areas or next to private residences.

These devices address two issues:

1. Ensures uniform filling of the form with a rigid mixture with a minimum water-cement ratio.
2. Removes the air mixture from the concrete, reducing porosity and providing a strong fine-grained structure with low hydrophobic properties.

For color

When mixing, the tile’s surface is painted in layers or in large quantities. Although it takes more work and skill, the first option is easier to use:

1. For the tile, 2 portions of concrete mixture are created – 2/3 of the volume of gray consistency and 1/3 colored with pigment additives.
2. Colored concrete is placed inside the blank.
3. Vibration equipment is turned on for 20 seconds.
4. After this, the form is filled with plain concrete and processed with a vibrating table for another 40 seconds.
5. At the last stage, the mixture is wrapped in polyethylene and moved to the drying place.

The color is added to the concrete mixer before painting. The tile’s color lightens, but the path’s design remains unchanged despite severe erosion to certain parts of it.

Mixing sequence

Determining which solution is required or discovering a recipe for a solution is not sufficient to produce a high-quality final product. It’s crucial to follow the mixing technology and read the detailed instructions before making the mixture at home.

Making your own mortar at home to use with paving slabs can be a satisfying and economical project. Paving slabs will stay firmly in place if you make a strong, long-lasting mortar with the correct ingredients and careful mixing.

Mix the cement, sand, and water in the appropriate proportions to create the mortar. To attain the required consistency, it is imperative to precisely measure and thoroughly combine these ingredients. Using the proper mixture will guarantee that the mortar sets properly and gives your paving slabs a sturdy base.

Take your time and place the paving slabs carefully when laying them. Your paved area will look better and have better structural integrity if all of the slabs are level and positioned correctly. Slabs that are laid correctly will be less likely to move or fracture over time.

The upkeep of your paved area is equally as crucial as the initial installation. Paving slabs can be kept in excellent condition and functional order for many years to come with routine cleaning and the occasional re-grouting. You can have a stunning and long-lasting outdoor area created by yourself by following these instructions and maintaining your paved surfaces.
