Do you have a thorough understanding of mud inhibitors?

Nowadays, during concrete construction, sand and gravel contain a lot of mud. However, the high sand and gravel content in concrete has a certain impact on the construction, and mud has a great impact on the performance of concrete. On the one hand, mud affects the bonding between the slurry and the aggregate, that is, the strength is reduced. On the one hand, increasing the water demand of concrete also reduces the strength of concrete. On the other hand, reducing the fluidity of concrete can easily cause concrete cracks.

1. Concrete mud inhibitor product – Introduction

This concrete mud inhibitor product can effectively reduce the interaction between mud and stone powder when the mud content and stone powder content are large. The adsorption of water reducing agent improves the workability of concrete. Concrete mud inhibitor is a new type of surfactant. It has a large amount of charge and can be preferentially adsorbed on the surface of soil and stone powder particles, neutralizing the charge on the soil surface, thereby reducing the adsorption of the soil and stone powder to the water-reducing agent. This increases the adaptability of the water-reducing agent and sand and gravel materials, and improves the workability of concrete.

2. Concrete mud inhibitor products – technical performance

1. Improve the workability of concrete under conditions where the sand and gravel contain a large amount of mud or stone powder. ;

　2. When the sand and gravel contain a large amount of mud or stone powder, reduce the slump loss of concrete over time;

　3. When the sand and gravel contain a large amount of mud or stone powder, Under the conditions of large mud volume or large stone powder content, the adaptability of water reducing agent and sand and gravel materials can be improved.

3. Concrete mud inhibitor products – homogeneity index

Based on the performance indicators of concrete mud inhibitors and user requirements, it complies with national, industry or enterprise standards.

IV. Concrete mud inhibitor products – usage methods

1. Suitable for different types of water reducing agents such as aliphatic, polycarboxylic acid, and naphthalene series;

2. When the amount of water reducing agent is 1.5-3.0%, (5-8) KG should be added directly to each ton of liquid pumping agent, and the amount should not exceed 10 kilograms

5. Concrete mud resistance Agent products – Precautions

1. When the type of cement is changed or new cement is imported, a compatibility test with the cement should be carried out.

2. If retarded concrete is required, the setting time should be checked in advance according to the concrete trial mix.

3. The dosage must be correct according to the test mix ratio, and the construction specifications should be strictly followed when pouring concrete.

4. When used in combination with other admixtures, its compatibility should be checked first.

5. During winter construction, in order to improve the early strength of concrete, the cement dosage of concrete should be appropriately adjusted.

6. Like conventional concrete projects, maintenance must be strengthened according to construction specifications. </p
