How Much Do You Know About Concrete?

2024-10-14

Concrete is a common building material in civil engineering and is widely used in all kinds of civil engineering. It is mainly used in the structural parts of buildings, such as foundations, walls, beams and columns. Concrete has high strength, durability and good plasticity, which makes it an ideal material for building high-rise buildings, bridges, roads and other infrastructure. Mass concrete refers to mass concrete with the minimum geometric size of not less than 1 meter, which is often used in high-rise building foundation, large equipment foundation, water conservancy dam and other projects. Because of its large volume, concentrated release of hydration heat of cement and rapid internal temperature rise, it is easy to cause temperature cracks, so it is necessary to pay special attention to the hydration heat and the volume deformation caused by it. Permeable concrete is a kind of building material with good permeability, which is widely used in roads, sidewalks, squares, parking lots and other places. It can effectively drain water, prevent water accumulation and flooding, reduce the consumption of groundwater resources and improve the utilization...

What Should be Paid Attention to in Concrete Construction in Spring?

2024-09-29

Because it is dry and windy in spring, the temperature difference between day and night is large, the temperature of concrete varies greatly in different time periods, and the temperature difference between inside and outside of concrete is also large, which is easy to form temperature shrinkage cracks. In this season, the air is dry, and the wind is stronger on the empty construction site floor, and the surface of freshly poured concrete loses water quickly, which is easy to form air-dried plastic shrinkage cracks. In order to ensure the construction quality, the following points should be paid attention to in spring concrete construction: I. Preparation before construction There will be some noise during the operation of concrete mixing station, which will have a certain impact on the surrounding environment and residents' lives. Therefore, concrete mixing stations should take effective measures to reduce the generation and spread of noise. (1) Check whether the construction equipment is in good condition, such as mixing station and delivery pump. (2) Check the formwork, steel bars, etc. to ensure that their sizes and positions...

How to Build an Environment-friendly Concrete Mixing Plant?

2024-09-27

The concrete mixing station is a kind of equipment specially used for producing and mixing concrete. However, in the production process, the concrete mixing plant usually emits a lot of pollutants such as waste gas, dust and noise, which has a certain impact on the surrounding environment and human health. Therefore, environmental protection requirements are one of the important factors that must be considered in concrete batching plants. In order to meet the requirements of environmental protection, ready mix concrete batch plant needs to take measures such as reducing noise, dust, waste residue emission, energy saving and emission reduction, and strengthening environmental management. The following are specific measures: I. Reduce noise pollution There will be some noise during the operation of concrete mixing station, which will have a certain impact on the surrounding environment and residents' lives. Therefore, concrete mixing stations should take effective measures to reduce the generation and spread of noise. (1) In terms of site selection, it should be as far away from residential areas and environmentally sensitive areas as possible, and at the same time consider...

What If It Rains Suddenly When Pouring Concrete? Stop or Not?

2024-09-25

Recently, I can always see workers complaining that it rains as soon as concrete is hit, and this job can't be done! It's been raining, and the concrete can't be hit. What about the construction period? What should I do if I stop or stop in the middle of pouring concrete? In order to avoid unnecessary losses, it is necessary for us to understand the problems encountered in rainy season construction and their solutions. I. The rainy season construction should do the following work: 1. The sand silo should be well drained. 2. Means of transport should have rain-proof and anti-skid measures. 3. The pouring bin surface shall be provided with rain-proof measures and waterproof covering materials. 4. Increase the determination times of aggregate moisture content and adjust the mixing water consumption in time. II. When pouring in light rain, the following measures should be taken: 1. Appropriately reduce the concrete mixing water consumption and the slump of concrete at the outlet, and appropriately reduce the water-binder ratio of concrete when necessary; 2. Strengthen the drainage in the warehouse and...

What Site Planning Does The Concrete Batching Plant Need?

2024-09-23

With the rapid development of modern cities, concrete mixing stations are more and more widely used. Let's talk about the site planning in detail! I. Choosing the site Choosing the site is the most basic work in the early stage of the station construction. We must pay attention to staying away from residential areas and high-voltage power lines, and it is best to be close to the main road for convenient transportation. The conditions to be achieved are "three links and one leveling": access, electricity supply, water supply and leveling the site. II. Clean up After the site is selected, it needs to be cleaned up, at least the road surface debris, silt and other factors that affect the site leveling and environment should be cleaned up and piled up in a unified way, so as not to cause pollution. III. The excavation Before excavation: it is necessary to do a good job of intercepting ditch at the top of the slope and do a good job of seepage control according to the soil conditions.

Problems That Are Easy To Occur In The Operation of Mixing Plant and The Troubleshooting Process And Solutions

2024-09-18

Concrete is widely used as the most important building material in the construction industry. The mixing station has realized the batch and continuous production of concrete. In the process of production and use, the mixing station will suddenly have various failures. Today, let's take a look at the common failures of the concrete mixing station. First, the motor of the main mixer cannot be started. I. The motor of the concrete mixer cannot be started It is difficult to start the motor of the main mixer, or it makes a "buzzing" sound during the starting process. At this time, it is necessary to stop it urgently and disconnect the power supply for inspection. Inspection process: Open the motor junction box, and measure whether the power supply voltage of the junction box is normal and whether there is a problem of missing phase. If it is found that the voltage is abnormal or the phase is missing, measure the output power supply voltage of the circuit breaker in the motor control cabinet and whether the phase is missing. If it is...
