Concrete M700 (m 700, heavy in 55, in50): pros and cons, properties, characteristics, where it is used

Due to its strength and versatility, concrete is a basic building material. It is composed of aggregates such as crushed stone, gravel, and sand, as well as cement and water. This mixture produces a substance that is strong, flexible, and moldable into a variety of shapes and sizes.

Concrete’s strength is one of its main benefits. Because it is resistant to extreme weather and heavy loads, it is perfect for constructions like roads, buildings, and bridges. Concrete also lasts a long time and is resistant to fire, which minimizes the need for regular repairs.

Concrete, however, is not without its drawbacks. Extreme temperature fluctuations are one of the conditions that can cause it to crack. In addition, a substantial amount of carbon dioxide is produced during the manufacture of cement, a crucial component of concrete, adding to environmental worries.

Concrete finds extensive usage in various fields. It is the fundamental element of construction for homes, businesses, and industries. Concrete can be used for a variety of purposes, including walls, pavements, foundations, and dams. Its properties provide both structural stability and visual appeal.

Advantages

Numerous benefits of Concrete B 55 M700 apply to specific areas and industrial construction.

• High strength – and the ability to efficiently perform large-scale work, large-scale structures
• Excellent aesthetic qualities, due to which concrete can be used for interior/exterior decoration of various structures and buildings, creating original objects
• High level of water resistance
• Good contact with other materials, excellent workability
• Versatility – M700 concrete can be used on any type of coating without compromising integrity and strength
• Excellent frost resistance characteristics
• Resistance to various types of aggressive environments

Where it is used

Large-scale heavy structures, which have strict requirements for strength and moisture resistance, are designed and poured using heavy concrete M700. For emergency repairs and restoration, concrete is frequently utilized. For the design of foundations for buildings with multiple stories, different types of reinforced concrete products are frequently poured from M700 (where increased loads are noted).

Concrete of this grade is popular in the creation of various types of hydraulic structures, roads, industrial floors. In the construction of ordinary buildings, concrete M700 is simply irrational, since its ultra -high strength will not be in demand, and the price is high.

Concrete is perfect for structures used in harsh environments, provided that it is partially submerged in water. Structures intended to be used in environments with high groundwater passage are also designed and built using concrete.

Properties

The B50 class of concrete is heavy and exhibits a very high strength. In industrial facilities, the solution is typically produced in response to special orders. Strengthening agents that encourage quick setting of the mixture are added to the mixture. Since cement is typically taken white, it offers a high level of resistance to different kinds of negative effects.

Crushed stone, sand, water, and additives are used in the composition in addition to the binder. Only the precise proportion of water to all dry ingredients, along with their superior quality, can ensure that the technical parameters outlined in the standards are met.

Plasticizers are required to improve the solution’s mobility and comfort during operation, but when used in the wrong amounts, they can weaken the monolith’s strength and worsen all of its characteristics. The preparation of Concrete M700 in specialized concrete mixers necessitates making sure the mixture is sufficiently homogeneous, which leads to compaction. Concrete that is incredibly strong can only be achieved by rigorous adherence to technology.

Characteristic

GOST and several documents define the set of requirements for M700 concrete’s qualities and attributes. The primary meanings are unambiguously expressed, though they may differ based on the ratios of ingredients, additions, etc.

• Strength – within 700 kg/cm2, strength class set to B50/B55
• Hardening capacity – very high
• Mobility – about P4-P5, makes it possible to fill in complex support structures
• Frost resistance – displays the number of freezing/thawing cycles that the monolith can withstand without deformation or cracks: for this frost resistance grade the level is marked within F300
• Moisture permeability – near W18, so that the solution is allowed to be used in the production of hydraulic structures

The amount of water in the composition and the rate at which the solution hardens can both be impacted by plasticizers added to the mixture. A significant amount of cement ensures quick hardening, and the addition can slightly shorten the solution’s hardening time. Because of these characteristics, concrete is typically carried by specialized transportation, and only skilled artisans handle it.

Such concrete is difficult to prepare on site, so it is best to order the necessary volume at the plant; many businesses in Moscow and the surrounding areas offer this service.

Composition and proportions

Because Concrete M700 is used in white cement, it has a distinct look. As a result, the solution is frequently used for bridge construction, building basement renovation, and decoration. Because the cement is composed of tiny clinker and does not require coloring (iron and manganese), it has a white color. As a result, the monolith is dependable, long-lasting, and resistant to sunlight.

There is very little water in the composition, no crushed granite, and no clay (a plasticizer is usually used instead). Every ingredient in the mixture needs to be of the highest caliber and adhere to all rules and regulations. Since the solution proves to be heavy, industries and places with specific operational requirements typically use this grade of strength.

The preparation of concrete M700 is typically done in a factory and is only done upon request. This solution creates a monolith that is robust, resilient, and fearless against nearly everything.

• A certain volume of Portland cement
• Crushed stone fraction 5-20 millimeters
• River clean sand with a grain index of 2.4-2.6
• Plasticizers based on polycarboxylates
• Water

Plasticizers, when properly combined, increase the mass’s mobility without weakening it. Relatively speaking, the monolith will lose some of its qualities without water. There is only one concrete mixer used to prepare the solution.

Concrete is a strong, long-lasting building material that is both adaptable and commonly used. Because of its durability, resistance to fire, and flexibility in shaping, it is the perfect material for a wide range of construction projects, from bridges to foundations. Nevertheless, there are drawbacks as well, like its susceptibility to breaking and high energy consumption during production. Selecting the appropriate type of concrete for a given application, be it residential, commercial, or infrastructure projects, is made easier by being aware of its properties such as compressive strength and setting time.

Industrial Application

There is absolutely no use of M700 concrete in private construction. However, it matters when putting complex hydraulic and industrial facilities into practice.

• Creation of structures operating in conditions of variable water levels – these can be reservoirs, dams
• Design and creation of objects that are partially submerged in water – various types of dams, bridge supports, etc.d.
• Ground floors of buildings, basements, floors in multi-storey buildings
• Cement-concrete pavements for roads and airfields

Because it provides a special combination of affordability, durability, and versatility, concrete is a necessary building material. Its resilience to diverse weather conditions and substantial weights renders it a dependable option for an extensive array of uses, encompassing everything from residential structures to expansive infrastructure undertakings.

Concrete has many benefits, but it also has some disadvantages. It’s vital to take into account factors like possible cracking, the requirement for routine maintenance, and environmental issues brought on by the manufacturing process. On the other hand, technological developments are always enhancing its sustainability and performance.

All things considered, concrete’s remarkable qualities and variety of applications continue to make it a mainstay of contemporary building. It is an essential material in the industry because its advantages frequently outweigh its drawbacks, whether it is being used to build roads, bridges, or residences.
