What does FCK mean? What do FC U and FC Y mean? 5

The standard value of the axial compressive strength of concrete is fck,"c"It means prism, and "k" means standard value. The compressive strength of the concrete cube is "fcu". Among them, "cu" means cube.

For example, when the concrete strength grade is C20, FCU, K=20N mm2 (MPa), that is, the standard value of the 28D compressive strength of the cube is 20MPa.

There are two ways to use fck:

Seems to be the fck new version usage.

FCU,K represents the standard value of the compressive strength of the concrete cube test block. The cube test block is generally 150mm side length. The FCU is the pressure that the Force Cube is subjected to.

k is the standard value and key value of the key.

The standard GB50107 "Concrete Strength Inspection and Evaluation Standard" stipulates that the standard value of cubic compressive strength refers to a value in the overall distribution of compressive strength measured by standard test methods for cubic specimens with a side length of 150mm made and maintained according to the standard method at the age of 28 days. The determination of the representative value of concrete strength shall comply with the following provisions:

1. When the difference between the maximum and minimum values of the strength and the intermediate value of a group of specimens does not exceed 15% of the intermediate value, the arithmetic average value of the strength of the three specimens is taken as the representative value of the strength of each group of specimens.

2. When the difference between the maximum or minimum value and the intermediate value of the strength in a group of specimens is higher than 15% of the intermediate value, the intermediate value is taken as the representative value of the strength of the group of specimens.

3. When the difference between the maximum and minimum values of the strength and the median value of a group of specimens exceeds 15% of the median value, the strength of the group of specimens should not be used as the basis for evaluation.

Method GB50081 "Standard for Test Methods for Mechanical Properties of Ordinary Concrete" stipulates that the curing conditions of the specimen should be cured in a standard curing chamber with a temperature of 20 2 and a relative humidity of more than 95%, or in a non-flowing Ca(OH)2 saturated solution at a temperature of 20 2.

In summary, for example, C30 indicates that the standard value of the compressive strength of this batch of concrete cubes is cured in a standard curing chamber with a side length of 150mm concrete cube specimens in 20 2 and a relative humidity of more than 95%, or cured in a non-flowing Ca(OH)2 saturated solution at a temperature of 20 2 for 28 days, and the concrete compressive strength measured is 30N mm2 or 30MPa, which has a 95% probability guarantee. If it is not a standard size, it needs to be multiplied by the corresponding size conversion factor.

Is it inside reinforced concrete, you ask? That represents the standard value of the shear strength of the steel bar, which can be found in the table and referred to the principle of concrete.

FC is an Internet buzzword, ** in forums, BBS and other online communities. FC is the abbreviation of the first two letters of "waste wood" pinyin, which means a person who does not understand the topic being discussed but comments on it.

The language of the web

The language of the Internet has two meanings: one refers to terms and vocabulary related to the Internet and computer technology and applications; The second is the language used by people when they use the medium of computer Internet to communicate and express themselves.

Network language is a new form of language that is different from traditional print media with the development of the Internet. In a concise and vivid form, it has been favored by the majority of netizens since its birth, and it has developed rapidly.

Internet languages include pinyin or abbreviations for the English alphabet. Numbers with a specific meaning and vivid online animations and **,At first, it was mainly a way for netizens to improve the efficiency of online chat or a specific need,Over time, a specific language has been formed。

FCUK, is a brand, an abbreviation for French Connection United Kingdom, whose products include clothing, perfumes, and cosmetics. It was founded in 1972 by British Stephen Marks and French fashion designers Pierre Dale and Nicole Fassi. In 1996, he began to use FCUK as a trademark, and obtained a UK trademark registration the following year.

Profanity in English is considered a modal word.

It means a fan coil unit.

The full name of FCU is FanControlUnit, that is, Fan Control Unit; Also known as fan coil unit. The three-speed fan and the permanent capacitor electric machine are used to make the fan the most energy-saving and energy-saving effect.

Household air duct unit features:

1. Suitable for families, shops, schools, supermarkets, offices, and entertainment venues.

and other air-conditioned places. The applicable construction area is 25m2-200m2, which is the preferred product to replace traditional household air conditioners.

2. Comfortable. It can be used to supply air directly to the side or to supply air through the air pipe, the indoor airflow is well organized, the enjoyment of air conditioning is high, and the unit can be freely configured with fresh air to further improve the comfort.

3. Noble. The ultra-thin indoor unit is placed in the local ceiling of the room, which produces the decorative effect of the air conditioner, making your space more noble.

4. Energy saving. The direct evaporation coil is adopted, and the energy is refrigerated and erected.

Air, its energy transfer effect is much higher than the refrigerant of the traditional ** air conditioner water and air energy transfer system, so that you have the enjoyment of ** air conditioning, but far more energy-saving than the traditional ** air conditioner.

5. Low noise. The indoor unit selects a through-flow fan or a multi-wing forward-tilting centrifugal fan.

Energy-efficient operation with low noise.

6. Easy to operate, the unit adopts computer control and remote control equipment, and the operation is simple and convenient.

FC stands for Red and White Machine.

FC (NES) Family Computer (Famicom for short) (or Nintendo Entertainment System) was the first generation of home game consoles released by Nintendo. From its launch in 1983 to its discontinuation in 2003, 62.91 million units were shipped worldwide. According to foreign media data, in 1990, 30% of American households had NES hosts.

At a time when the United States was experiencing the Great Depression of the video game industry due to the "Atari Collapse", the launch of FC laid the foundation for the modern video game industry, and Nintendo became the pioneer of the modern game industry, setting the standard for modern video games in many ways.

History. The early 80s was the era of Japan's booming economy, and the overwhelming advantage of FC was vividly reflected in this ** era, with cumulative sales of more than 100 million units. FC was the first massively popular game console in China, and probably the most popular one, which should be unforgettable for people in the seventies and eighties.

In the early 80s, there were more than 16 types of TV game consoles in the Japanese market, but the total market size was less than 3 million units. On July 15, 1983, Nintendo launched a new era in the FC writing game industry, and the sales of the machine exceeded 3 million units in less than a year, setting off an unprecedented popularity.

On July 15, 1983, the FC was officially listed, and since the completion of the new plant in March, Nintendo's stock price has skyrocketed, reaching an all-time high of 6,300 yen per share (a 40-fold increase in three months).

In the early nineties, a series of learning machine products launched by China's Xiaobawang company are products that infringe intellectual property rights, and their imitation objects are the FC game consoles sold by Nintendo of Japan.
