Polycarboxylic acid water-reducing agent is an important building material widely used in concrete engineering. It can improve the performance of concrete to a certain extent under reasonable use. However, once it is used improperly, some problems will be encountered. Next, let's take a look at some

In the use of concrete admixtures, not only can reduce costs, improve economic benefits,but also a wide range of uses. So, what is the effect of concrete admixtures?What effect does concrete admixture have? Concrete admixtures have many effects, each has its own role. For example, water reducing age

In order to ensure the quality of concrete, users tend to add water reducing agents to improve the quality of concrete when they allocate concrete. Now, polycarboxylic acid water reducing agent, as a new generation of water reducing agent, has been praised by researchers and some users from the begi

Water reduction is an important effect of surfactant on cement hydration. Water reducing agent does not affect the working condition of concrete, can reduce the unit water consumption; Or under the condition of not changing the unit water consumption, can improve the workability of concrete; Or admi

Polyethylene glycol 4000 and polyethylene glycol 6000 belong to the polyethylene glycol PEG series of products, which are used in the pharmaceutical industry for suppository, paste preparation; It is used as finishing agent in the process of papermaking. In the process of rubber processing as an add

The main difference between dispersants and surfactants is that dispersants improve particle separation in suspension, while surfactants are substances that reduce surface tension between two phases of a substance.Dispersant is a form of surfactant. But all surfactants are not dispersants. In additi

1.Mixing concrete when you can add a certain amount of water reducing agent, after mixing evenly, can improve the fluidity of concrete, make its structure more stable, improve the strength, but also to ensure that when the strength of concrete does not change, save the amount of cement, so water red

Concrete water-reducing agent is a chemical additive commonly used in concrete. Its function is to reduce the amount of cement in concrete without affecting the strength of concrete, thus reducing the cost of concrete. This paper will introduce the type, principle and application of concrete water r

Causes of cutting fluid corrosion of metal:1. Cause of corrosion1) The proportion of concentrate in cutting fluid is low.2) The pH value of cutting fluid is too high or too low. For example, when PH > 9.2, aluminum is corroded. Therefore, the appropriate pH value should be selected according to the
