The Advantages and Disadvantages of Free Foundation Concrete Mixing Station

2024-09-12

What is a foundation-free concrete batching plant? Free foundation, also known as steel foundation, refers to replacing concrete foundation with steel structure foundation. In fact, the foundation-free concrete mixing station doesn't really need to do foundation construction, but it doesn't need to drive such a deep foundation like the fixed concrete mixing station. It also needs to harden the ground, make a shallow foundation, and put all the equipment parts on a heavy steel chassis. The foundation-free concrete mixing station is a complete set of automatic concrete mixing equipment, which is composed of batching, mixing and electric control. The concrete mixing plant eliminates the process of designing and installing the foundation, greatly saves the time and foundation cost for customers, and can be relocated for secondary use. It is suitable for medium-sized and large-scale construction sites, prefabricated factory, high-speed rail and highway and Water Conservancy and hydro-power projects and commercial concrete production lines.

The foundation-free concrete mixing station is different from the traditional concrete mixing station Steel foundation:...

What Are The Layout Methods of The Concrete Mixing Plant?

2024-09-12

The layout of the concrete mixing station mainly includes the following: I. Vertical concrete mixing station The material only needs to be lifted once, and then it falls to each working procedure by its own weight. This layout has the advantages of high efficiency, small floor space and easy automation. However, its disadvantages are complex structure, high manufacturing cost and high installation height. II. Horizontal concrete mixing station The materials need to be lifted twice, first to the storage hopper, then to the mixer after weighing. This layout is simple in structure, low in cost and small in building height. But the disadvantage is that the efficiency is lower than that of vertical concrete mixing station. III. Mobile concrete mixing station The loading, storage, weighing, mixing and unloading devices are installed on the same base. This layout is compact in structure, easy to carry and can directly enter the construction site, thus shortening the transportation distance of concrete and improving economic performance. But the disadvantage is that the general production efficiency is not high and the failure rate is relatively...

Influence of Low Temperature Conditions on Concrete Performance

2024-09-09

I. The influence of low temperature conditions on the early performance of concrete It is proved by experiments that the lower the temperature of concrete is, the longer the initial setting time and final setting time will be, and the longer the final setting time will be. Under the condition of low temperature, the slump of concrete should generally not exceed 100mm, and the bleeding should be reduced as much as possible and set as soon as possible. At low temperature, bleeding water will stay on the concrete surface for a long time, which will affect the normal finishing process. Finishing the concrete surface without treatment is one of the main causes of concrete surface defects. If the surface bleeding water is pressed into the concrete during the plastering process, the water-cement ratio of the surface part will increase, resulting in the decrease of strength, air content and surface impermeability. Concrete materials should be designed to minimize bleeding. If bleeding occurs during construction, it should be removed before plastering. 1. The influence of low temperature conditions on the strength of...

What to Pay Attention to When Cleaning The Concrete Mixer

2024-09-04

The Importance of Regular Cleaning Concrete mixers often come into contact with materials like cement and sand, which can accumulate over time and reduce the machine's efficiency. If left uncleaned, concrete may solidify inside the mixer, making cleaning more difficult. Regular cleaning not only extends the machine's lifespan but also enhances operational efficiency. Use the Right Cleaning Tools and Methods When cleaning a concrete mixer, it's essential to use appropriate tools, such as a high-pressure water gun and specialized cleaning solutions. Avoid using sharp objects to prevent damage to the machine's surface. Key areas to focus on include the mixing blades, the inner walls of the mixing drum, and the discharge chute, as these areas are most prone to concrete buildup. Cleaning Steps Preparation: Turn off the power to the mixer and ensure there is no remaining concrete inside. Initial Cleaning: Use a high-pressure water gun to wash the inner and outer surfaces of the drum, removing large chunks of concrete residue. Deep Cleaning: Apply cleaning solutions and use brushes to thoroughly clean any remaining concrete, especially around the mixing...
