Cement is widely used as a building material due to its high bonding properties and strength after curing. It includes the original clinker and additional mixtures that affect the color and speed of drying. Dry mixes differ by strength grade, where there are goods for domestic and industrial use. Every year there are all new types of additives, as well as manufacturers of this substance. It will be useful for all novice craftsmen and experienced builders to consider the ranking of the best cements recently released in order to find the best option for screeding floors, laying walls, creating a paving area, paths in the garden, and making concrete products.
The best cement brand M400
Such a substance is used to create a screed or irresponsible masonry partitions inside the house and apartment. Its strength is sufficient to withstand loads of moderate severity.
Such cement is also optimal for waterproofing basements and basements, as well as leveling floors with large differences.
Portland M400 Hercules - for floor screed

- environmentally friendly composition, marked with the logo "ECO";
- can be used both in dry and in wet areas (basements, cellars, tunnels);
- gypsum not more than 5% in the composition;
- contains active minerals that increase strength, up to 20%;
- in the case of corrosion on a nearby metal, it does not adopt its effect on itself;
- high resistance to impact with class 32.5B;
- durable operation;
- behaves well with a strong decrease in temperature (up to -40 degrees);
- Classic gray color, well combined with other types of solutions in shades that will not stand out when creating a blind area.
Minuses:
- cost for 5 kg starts from 50 rubles;
- the shelf life of only 2 months will require repair in the near future after purchase;
- cannot be operated outside.
Cem CEM II 32,5 (M400 D20) gray De Luxe - for blind area
This is the best cement for creating a blind area on the street, because the substance is designed for external use, which does not lead to cracks and their regular sealing from temperature differences.
The created solution has a strength of 32.5 B, which ensures good adhesion of all components. The dried blind area can withstand loads up to 330 kg per cm2. Cement is supplied in paper bags of 50 kg, which is convenient for large volumes of work.
Pros:
- price from 260 kg for a huge bag;
- has high water resistance and tolerates low temperatures;
- long service life of the created structures;
- contains additives that promote rapid solidification and strength, the rate of which is 330 kg / cm2 during compression;
- You can perform installation work at a temperature of +5 to +30 degrees;
- after 28 days it gains hardness and withstands load tests up to 32.5 MPa;
- starts to set in 75 minutes, which gives enough time to fill the blind area, and to level off smoothly without hillocks and sags;
- specific activity of radionuclides with an effective result in the range of 370 Bq / kg;
- full compliance with construction GOST 31108-2003.
Minuses:
- 50 kg bags are difficult to transport and carry;
- stored only 6 months;
- Do not work at temperatures below +5 degrees.
The best cement brand M500
The five hundredth brand of cement has more enhanced strength characteristics, which makes it possible to use it not only for screeding floors with loads, but also to create a solution for walling and pouring the foundation for a building.
Holcim Tared 50kg CEM II / A-K (W-I) Class 42.5N - for the foundation for a house
This is the best cement for the manufacture of concrete and a solid foundation that will withstand the load from the subsequent construction of walls even in several floors. The mixture class has an indicator of 42.5N, which provides rapid solidification and endurance.
Mineral supplements eliminate subsequent cracking and peeling. Cement is supplied in white and red bags of 50 kg, which is optimal for a large amount of work.
Pros:
- meets increased strength requirements for load-bearing structures;
- suitable for use both inside the building and outside;
- flexural strength 78 kg / cm2;
- contains plastic and mineral additives;
- maintains loading to 433 kg / cm2;
- can be delivered in pallets of 30 bags and weighing 1500 kg, which is convenient for one purchase and one-time transportation with a large volume;
- classic gray color, without blueness;
- the cost of the entire bag from 290 rubles;
- binds well with incremental fractions of various sizes;
- It has a normal time for hardening, which allows you to correct nodules or stains even in a soft form, so that later you do not have to cut them with a power tool.
Minuses:
- can cling with small voids when working outside in the cold;
- the bag has no pronounced edges, for which it would be convenient to take when transferring to the workplace.
Stone flower M500 D20 - for especially responsible laying
This is the best cement for creating masonry binders, because its tensile strength is 500 kg / cm2. The composition contains polymeric additives that accelerate the setting and promote increased resistance to cracks.
In the finished mixture is allowed to add glue and other substances that affect the adhesion and prevent freezing when working in cold weather. The dry product is realized in bags of white-orange color by packaging of 40 and 50 kg.
Pros:
- normal hardening solution, ideal for kneading and styling, followed by leveling without solid elements;
- simple cooking method, both manually and mechanized;
- cost from 270 rubles for 50 kg;
- mineral additives in the composition;
- suitable for all types of exterior and interior work with the use of solutions;
- the index of ultimate compressive strength is 500 kg / cm2;
- can be sold in pallets of 40 pieces each with a weight of 2000 kg, which is convenient during transportation and large construction volumes;
- ecologically safe;
- corresponds to GOST 28013-98;
- high waterproof and frost-resistant characteristics;
- long service life of the finished foundation or seam masonry;
- adhesion with building materials and base 0.3 MPa.
Minuses:
- shelf life dry mix 6 months;
- bags are inconvenient to take (smooth oval corners on the package).

This type of building mixture has a special strength and is suitable for screed floors under high loads from vehicles or racks. Poured out of it and reinforced concrete structures.
Polymer white M600 Rusean - for reinforced concrete frames
This is the best cement for casting reinforced concrete structures of frames (railings, flowerpots, balconies, ornaments, sculptures) due to two factors: high compressive strength within 54-57 MPa, which is equivalent to a load of 570 kg per cm2, as well as a pleasant white color that does not require subsequent coloring of the product. The latter is achieved through polymer additives, giving whiteness of 82-84%.
Pros:
- fine grinding provides a fine structure suitable for self-leveling floor;
