The development direction of water reducer
With the continuous development of the social economy, more and more concrete products appear in our country, which is why higher requirements are put forward for the quality of concrete structures. At present, the development of concrete water reducer mainly includes the following aspects: (1) Multifunctional water reducer has been widely used. As the global demand for concrete strength continues to grow, multifunctional additives have been widely promoted in various industries in different countries. Among them, the multifunctional composite water-reducing agent as a high-performance additive has the obvious water-reducing effect and can meet the requirements of high-strength concrete production, thereby greatly improving the economic benefits of the project. (2) There are many types of water-reducing agents. Superplasticizers have been studied for many years, but these are only limited by their high strength and durability. Therefore, it is necessary to strengthen the research and development of new materials and new technologies and varieties that can be used to manufacture high-performance materials. In order to conform to the current economic development situation, the ready-made water-reducing agents are more diversified, which has contributed to the wide promotion and use of high-efficiency concrete water-reducing agents and is in line with the development needs of the current construction market. (3) Reduce the production cost of water reducing agent. In the manufacture of superplasticizers, the goal of saving production costs has been achieved, and unnecessary consumption and waste can be reduced. At the same time, industrial waste can also be used for process research and development. formula. Add the water-reducing agent to make high-performance, low-cost, high-quality water-reducing additives (such as sodium lignosulfonate powder used in construction) to improve the competitiveness of water-reducing agents in the mixed market. (4) Strengthen the research on the mixing method of superplasticizer. After experimental research, it is found that the choice of mixing method and mixing time can significantly improve the production efficiency of superplasticizers. This increases the performance of the high-performance water-reducing agent, which not only ensures the quality of the concrete structure but also improves the overall benefit of the project. (5) Continuously improve additive standards. Nowadays, as the number of concrete additives(such as naphthalene sulfonate in concrete) in my country has steadily increased, the requirements for additive standards in all walks of life in the world are also increasing. When using superplasticizers, it is necessary to formulate a complete set of technical requirements system, put forward higher requirements for the use and technology of new additives for concrete, and use them in accordance with national regulations and standards for the promotion of additives in different countries. market. With the continuous increase in the types of concrete water reducers, superplasticizers have obvious advantages as commonly used concrete additives. Additives with high water reducing rate, good fluidity and stability, and superplasticizer can effectively guarantee the quality of creta mixture and have been approved and recommended by engineers. The research and development of high-efficiency water-reducing additives can ensure the quality assurance of construction projects and improve the level of construction technology, thus contributing to the rapid development of the construction industry. The development of the mechanical engineering industry.
Temporary Fencing
Temporary fencing is the most widely used method for protecting construction sites or handling large amounts of people at big events. We are used to seeing them in the line for entering an event such as a concert or sports competition, and we also see them around construction sites. What is the purpose of temporary fencing, and why are they consistently used? What are the rules for using temporary fencing? What are the differences between the available models? Purpose of temporary fencing The reasons for using temporary fencing depend on what you will use it for. Basically, temporary fencing is used in two areas: 1) Construction and 2) Events. Construction. Temporary fencing is vital on construction sites for health and safety reasons. If you start thinking of the number of risks a construction site has for people passing by and neighbours, you will quickly realise how vital the temporary fencing is. For instance, consider the risks associated with: - Demolition of existing structures - Excavations - Slips, trips and falls - Temporary electrical installations - Partially constructed structures - Stored construction materials - On-site plant and equipment An accident-related to any of these areas can easily make your company responsible if you did not have the proper temporary fencing in place. You want to have the proper protection for your construction site to prevent unauthorised people going in to steal or even kids going in for "fun". If you are responsible for a construction project, you are responsible for securing the area to protect neighbours and others from the community. To successfully prevent access from unauthorised people to your construction site, you need temporary fencing that is unbreakable. It is not easy to find secure temporary fencing, but there are products out there such as No Thru™ temporary fencing that guarantee an unbreakable temporary fencing system. This is key to comply with strict governmental regulations. For example, on Victoria's government site, the Construction site security fencing - WorkSafe lists the requirements for proper temporary fencing in construction sites. Under security fencing, you will see this on the second bullet point. Well-constructed — gates and joints in fence sections should be securely connected, without any weak points for entry Weak points are a common issue in temporary fencing. Usually, to break through the fencing, all it takes is to remove the top bracket, lift the fence panel from the foot, and open the temporary fencing system. Fortunately, No Thru™ temporary fencing has solved the issue by removing the top bracket and having it all locked up on the foot. Therefore, the No Thru™ products provide you with a regulation-compliant solution for your construction site. Events. Temporary fencing is also vital for concerts, political events, and even iconic sports events such as Formula 1 Grand Prix. The number of people who attend big events requires temporary fencing to control people's flow, prevent unauthorised access to certain areas, and protect spectators from any possible danger such as car crashes in a Formula 1 race. Did you know that there are more than 300,000 people in attendance for the Australian Grand Prix in Melbourne over a four-day period? The popular Formula 1 race involves racing cars competing on a closed public street circuit in Albert Park, reaching speeds of 320 km/h or more! Of course, a spectacle like this requires temporary fencing to protect the health and security of the participants and the spectators. It poses a logistic challenge to secure the area effectively, without allowing anyone to cross the barriers but also making it temporary and friendly for the environment. The Formula 1 Grand Prix event is just an example to prove the importance of high-quality temporary fencing. However, it is still a particular event with its own set of regulations, as you can see on their latest 2016 regulations from the Victoria government site. Other events such as concerts have different challenges, people are usually a lot more excited, and their behaviour can be sometimes unpredictable. Guaranteeing safety is the biggest concern for the company organizing the event but also preventing people from accessing the event without paying. Just as was mentioned for construction sites, standard temporary fencing is at risk of being breached easily by removing the top bracket. Therefore, the No Thru™ temporary fencing becomes the recommended method to prevent this from happening. How does it work? The No Thru™ temporary fencing system contains a locking element on the right-hand side of the foot and a brace on the left-hand side. The lock and the brace prevents the fence panel from being lifted. The brace also has another purpose: to stop the foot from rotating and creating a gate or opening to the fence. The No Thru™ system also provides you with options to define your access points. Since the fence panels are locked from lifting, there is no way to create other openings besides the ones that you want. Therefore, there is no need for monitoring all the perimeter of your temporary fencing. You can just rely on the boundaries you created to provide security to participants and spectators. What are the options available? Lee Brothers Fencing is an option for big events. They even supplied fencing for the 2016 Grand Prix of Formula 1. However, there is the danger of having weak points on their fences. They do not use No Thru™ temporary fencing system, and therefore the top bracket can easily be taken off and the fences breached. No Thru™ temporary fencing is obviously the best option for securing your construction site or event. With their unique lock and brace on the foot, no one will be able to breach your fences, and you will enjoy the peace of mind that everything will be secured, your tools on a construction site, or your dear clients of a big event.
