Mortar for paving slabs: proportions with plasticizer

A solution for paving slabs, the proportions of whichwill be presented in the article, you can prepare yourself. The need for this kind can arise after you complete the construction of the house and proceed to the development of the adjacent territory. You can make paving slab without using expensive equipment, in addition, you do not have to attract additional labor, and not much will be spent on your own labor.

Preparatory work before mixing mixture

In order to prepare a solution for pavingtiles, the proportions of which will be described in the article, you need to do some preparatory work, which consists in taking care of the availability of the entire set of tools and materials. Thus, a concrete mixer is useful, but it can be replaced by capacity and shovel if necessary. Among other things, useful:

• modifier;
• cement;
• water;
• sand;
• crushed stone;
• a plasticizer;
• coloring pigment of the required color.

Recommendations for the preparation of solution

In order to achieve a positiveresult, you will need to follow the recommendations. It must be remembered that the quality of the closed concrete largely depends on the properly selected components, in addition, there is a need to precisely observe the proportions. For this reason, it is necessary to buy portland cement grade M500, in which there should be no foreign additives. To the rubble, too, requirements are expressed, expressed in fractionality within 5-10 mm. In addition, the rubble must be washed. As for the sand, it must be a large-river river. In order for the tile to have a color, it is necessary to prepare a high-quality pigment dye. Will be necessary and plasticizer. But the shutting should be done using only pure water.

Composition of concrete mixture

A solution for paving slabs, proportions forwhich the master must know before commencement of mixing, must correspond to the qualities of frost resistance. Do not replace Portland cement grade M500 with M400, since the first one belongs to a group of cements that are characterized by considerable strength and early setting when compared to M400 concrete. Cement M500 can contain mineral additives, the volume of which does not exceed 20% of the total amount, but sometimes this quantity is not contained in the cement. Thus, PC II / А-Ш 500 has mineral fillers, but PC I-500 has a pure composition, and products made of it are able to withstand a load that reaches 500 kg / cm².

A solution for paving slabs, proportions forwhich is important to observe, it is necessary to prepare using gravel with resistance to abrasion in the minimum limits equal to M800, this implies the strength of high or normal level. It is important to pay attention to the frost resistance index, which should be within F300-400, and this material will correspond to the characteristics of granite gravel. In the sand, there should not be more than 3% impurities.

Additional components

The use of plasticizers, as well assuperplasticizer allows you to manufacture products that, after casting in forms, do not need to be subjected to vibration. If you reduce the volume of water in the composition, you can get a solution that will differ in the qualities of self-sealing, in addition, it will be characterized by high strength. In order to obtain the product of the desired shade, iron oxide pigments should be used, which perfectly resist the effects of ultraviolet, water and high temperatures. Strengthen concrete can be reinforced with polypropylene fiber, which can replace metal reinforcement.

Mixing proportions for paving slabs

Mortar for paving slabs, proportions withplasticizer for which are presented on the packaging of the last ingredient, can be used for work. So, for mixing, you can apply the following proportion: 1: 2: 2 (the first component - water, the second - cement, the third - crushed stone). Before starting work, it is necessary to prepare the necessary amount of cement. So, if you take 50 kg of a non-additive mixture, then it will need 15-20 liters of water, which is approximately two buckets. The liquid must be poured into the concrete mixer. The plasticizer should be dissolved in a small amount of water, the temperature of which should not exceed 50 ° C. After the mixture has to be added to the mixer and mix well.

Sidewalk tile, solution composition, proportions forthe preparations of which are mentioned above, is made quite simply. The next step is to fill in pigments, which should be used from the calculation of the standard prescribed by the manufacturer. Now the rubble comes into play, it must be used for the aforementioned volume of constituents of the solution in the amount of three buckets per 12 liters. Crushed stone must be poured into the mixer. Now you can add a bag of cement, the volume of which is 50 kg. Make the addition with buckets, thoroughly mixing after each. Then you can add another bucket of rubble and mix. After the mixer can add four buckets of sand and mix. In conclusion, we have to add another bucket of rubble, mix the mass well and pour it into molds.

Recommendations on proportions

Mortar for laying paving slabs, proportionswhich allow you to get strong products, you need to shut up on the recommendations presented here. In order to prepare a plasticizer solution, it is necessary to use the composition in dry form in a volume equal to 0.7% of the cement mass. Water for dissolution should be warm. After the plasticizer, the pigment colorant can be added to the composition, it should be used in a volume equal to 2-5% of the total mass of the cement.

Change in the proportion to increase the strength of concrete

If you are wondering about what proportionsolution for paving slabs is necessary, then you probably will be interested in the fact that the composition can be added glass alkali-resistant or polypropylene fibers, which are necessary to increase the durability of the product, in addition, if you add similar ingredients, the tile will have the qualities of impact resistance and durability, which is very important. Choose fibers that are required, the length of which varies from 10 to 20 mm, while the diameter should be 10-40 μm. Use them in the amount of 0,8-1 kg per cube of concrete mixture. If you apply this reinforcement, you can achieve an increase in the strength properties of the finished product.

Finally

If the proportion of the solution for manufacturingpaving slabs were chosen correctly, then after the preparation the grout will be held on the working surface of the trowel, but if it is shaken easily, the mixture will immediately blur. In the absence of a concrete mixer, it is not possible to achieve the desired effect, in addition, it will take much more time to close the structure, but in an individual building this approach is advisable to use.
