Special additive

Special additive for grouting material It is a chemical agent used to improve the performance of grouting material. Product features: Special additive for grouting material can significantly improve the fluidity, stability and durability of cement-based grouting material. It uses the natural expansion characteristics of the expansion agent and the reaction with cement components to make the material have micro-expansion, thereby compensating for the volume shrinkage during cement hardening. Application field: This additive is widely used in equipment foundation installation, anchor bolt anchoring, concrete structure transformation and reinforcement, engineering repair and emergency repair and other fields. Technical advantages: By adding fly ash and microsilica powder, the volcanic ash effect and micro-aggregate effect of the material can be effectively improved, and the cold resistance and corrosion resistance of the material can be enhanced. Certain additives such as pumice powder can effectively enhance the performance of the material. If used with a water reducer, it can have a better effect. Environmental protection: Special additives for grouting material are usually environmentally friendly products, do not contain harmful substances, and meet environmental protection requirements. Durability: Special additives for grouting materials can improve the durability of the material, making the internal structure dense after hardening and forming, and the durability is better. Water reducer and expansion agent: Special additives for grouting materials include water reducer and expansion agent, which have a great influence on the fluidity, mechanical strength and dimensional stability of grouting materials. Defoamer and flocculant: In order to solve the problem of bubbles generated during the mixing process of grouting materials, defoamers such as polyethers and silicones are usually added. Flocculants, also known as underwater anti-dispersants, are an important component of underwater grouting materials and can be used to prepare underwater grouting materials that meet the requirements. Special additives for grouting materials are an important building material that can significantly improve the performance of grouting materials and engineering quality.
