Water reducing agents are considered to be the latest generation of high performance water reducing agents and are sought after and favored by industry professionals. However, in practice, it is not perfect. People always expect it to be safer, more efficient, and more adaptable than traditional naphthalene-based water reducing agents in application. However, in engineering practice, we always encounter various problems. How to choose a suitable concrete water-reducing agent? How to solve the problems that are easy to occur in concrete?
What is currently on the market? There are many brands of concrete water-reducing agents, the quality is uneven, and the prices are high and low! Faced with this situation, how should you choose?
Well, let’s get back to the topic, let’s still choose the concrete water-reducing agent. !With the development of the concrete industry, the composition of concrete has changed from a single cement component to a variety of admixtures and cement additives. Water reducing agent is one of the most important types of cement additives. It promotes the application of industrial production waste in concrete, improves concrete properties, saves cement, and reduces production costs.
How much do you know about the selection of concrete water-reducing agent?
The selection of concrete water-reducing agent should be based on the construction performance and requirements of the concrete to select the type of water-reducing agent. Generally, naphthalene-based water-reducing agent is sufficient for concrete, which has early strength. High-strength water-reducing agent can use high-efficiency water-reducing agent and high-performance water-reducing agent. Various water-reducing agents have their own characteristics and cannot be used interchangeably. It is inappropriate and uneconomical to use high-efficiency water-reducing agents as high-performance water-reducing agents and standard water-reducing agents as early-strength water-reducing agents.
Select the brand of water-reducing agent based on the technical level, convenience, and economy of the water-reducing agent manufacturer. Most water reducing agents are compound water reducing agent products, either liquid or powder. The mixing station is self-configured, lacks professional personnel, and the dosage is inaccurate. It seems to save costs, but in fact, improper use causes greater harm and economic losses.
Determine the brand of water-reducing agent based on the compatibility of cement and water-reducing agent. Incompatibility between concrete water-reducing agent and cement will affect concrete quality and normal production. Therefore, it is necessary to do relevant experiments before using the water-reducing agent, and use it only if there are no problems.
For concrete adaptation, the materials should be fed evenly during production and construction, and the measurement should be accurate. The amount and composition of the water-reducing agent should be adjusted in a timely manner according to the situation.
Concrete water-reducing agent has become an indispensable component of modern concrete, giving concrete good working performance, volume stability and high durability. Polycarboxylate water-reducing agent is a leap and a challenge. Therefore, users of water-reducing agents should choose the most cost-effective water-reducing agent according to the performance requirements of concrete.
