Concrete admixtures are natural or manufactured chemicals or additives added during concrete mixing to enhance specific properties of the fresh or hardened concrete, such as workability, durability, or early and final strength.

Water-reducing admixtures essentially neutralize surface charges on solid particles and cause all surfaces to carry like charges. Since particles with like charges repel each other, they reduce flocculation of the cement particles and allow for better dispersion.
The future farm may be like this!
[China Agricultural Machinery Network Industry News] Agriculture is one of the guarantees of people's lives. The development of agriculture is inseparable from the efforts of people all over the world. So what will the future development of agriculture be like? What will the future farm look like? Is it curious? Next, look forward to the future of agriculture and take stock of 10 vertical farm programs.
1. "Eco pods"
"Eco pods"
In the economic downturn, many of the projects under construction in Boston, USA, are in a state of suspension. Since there is not enough money to continue construction, they have become a rotten building with only a frame structure. Boston Haller-Yune Architects believes that these unfinished buildings are actually available, so they proposed to use a "ecological pod" on these unfinished buildings. This so-called "ecological pod" is actually an "algae tank" that can be used to produce biofuels. The robotic arm can rotate these “ecological pods†to ensure that each “ecological pod†receives the same light.
2. Canyon Life Cooperative
Canyon Life Cooperative
The “Canyon Life Cooperative†program was designed by Los Angeles Standards Architects and is one of the finalists in the “Dallas Vision†design competition. The design was inspired by the Assazi village on the cliff side of the Grand Canyon of Colorado, designed to bring the concept of a commune and sustainable ideas to the heart of the city. This cooperative can accommodate 1,000 residents and has sufficient sustainability. Agricultural production, electricity supply and water use can all be solved internally.
3. London Bridge Vertical Farm
London Bridge Vertical Farm
In fact, the design idea of ​​“London Bridge Vertical Farm†comes from its history. For a long time in the past, the London Bridge was where merchants and citizens gathered and traded their products. The British Institute of Architects has specially organized a design competition, hoping that architects will be able to fully imagine and design a new look for the London Bridge. In this imaginary competition, Chetwood Architects designed the "London Bridge Vertical Farm" to win the championship. In the “London Bridge Vertical Farm†program, London Bridge is a complex of agricultural, energy and commercial functions that includes a large organic vertical farm, solar powered spires and wind turbines, and a commercial center. In the business center, there are fresh food markets and retail areas. In addition, there is a dock connected to the bridge, so people can also trade on the water.
4. “Green Project†in Austin, USA
"Green Project" in Austin, USA
For a long time, Mithun Architects has been known for its sustainable design. The “green engineering†program they designed for the city of Austin, USA, was not disappointing. In the design, architects hope to transform an abandoned water purification plant into a vibrant green community. When the project is completed, the total area of ​​the community will reach 2.5 million square feet, and the interior will be divided into residential areas, office areas, commercial areas and hotel areas.
5. Seattle “Ecological Laboratoryâ€
Seattle "Ecological Laboratory"
The Bell Town community in Seattle, USA, has been building urban community garden projects since the 1980s. The “ecological laboratory†designed by the American Weber Thompson Architects, while still continuing the traditional agricultural production of the community, has also expanded it. The “ecological laboratory†integrates elements such as residential areas, educational areas and public markets, and the energy consumption and water consumption of the entire building are close to zero.
6. Green Skyscraper
Green skyscraper
One of the main obstacles to building large urban farms in cities is that they invest too much. In fact, it is difficult to avoid high investment in every special purpose building. However, Korean architect Daekwon Park's design is particularly smart, using existing skyscrapers to create a modular vertical farm structure. In this vertical farm structure, different types of modules play different roles. They are installed outside the skyscraper to capture the large planting space. Although this idea is unlikely to be implemented for the time being, it represents the direction of future urban farms.
7. Taiwan China Trust Commercial Bank Headquarters
Taiwan China Trust Commercial Bank Headquarters
The China Trust Commercial Bank headquarters is also a green skyscraper and is currently under construction. When it is completed, it will be a building with considerable energy utilization. The building features green roofs and vertical courtyards. In addition, there is a public green space in the central courtyard. The building is fully environmentally friendly, and in addition to having a green roof, the architects have promised that the project is a truly eco-friendly project. The façade of the building features a new technology smart curtain wall that allows more sunlight to shine through the floor-to-ceiling windows and automatic sensors.
8. "New York Green Tower"
"New York Green Tower"
The big difficulty in architectural design is that ideas must go before the public. For the "New York Green Tower", the remarkable feature of this building is the sky garden. The idea of ​​this sky garden may be considered by many to be quite magical. However, once the project is approved and ready to start construction, the public may become accustomed to this idea. The "New York Green Tower" was designed by American architect Daniel Liboskin.
9. O-type vertical farm
O-type vertical farm
In the face of a growing population and a gradual backward agricultural system, architect Oliver Llorest proposes a solution that can partially solve this global crisis, the “O-type vertical farmâ€. His design is not only concerned with food production issues, but also takes into account the ideal location of the building in the city. O-type vertical farms must be located in the right place to be able to perform at a great level.
10. Dubai “Seawater Utilization Vertical Farmâ€
Dubai “Seawater Utilization Vertical Farmâ€
Dubai has always been known for its novelty and beautiful architecture. The concept of “water use vertical farms†is also a typical example of all the novelty designs in Dubai. In this vertical farm, the disc-shaped structure is a farm. Seawater flows through the pipes in the center of the building, which cools and replenishes water through the seawater flowing through them. This unique design may be somewhat impractical, but its design philosophy is to take advantage of all the natural resources available, and a more practical alternative can be used in the implementation process.
