What is a water reducer? The water reducer is divided into water agents and powder agents. The solid content of water agents is generally 20%, 40% (also known as mother liquid), and 60% powder solid content is generally 98%. It is a concrete admixture that can reduce mixing water consumption while maintaining an unchanged concrete slump. Most belong to anionic surfactants, lignin sulfonate, naphthalene sulfonate formaldehyde polymer, etc. Adding concrete mixture to disperse cement particles can improve its work, reduce unit water consumption, improve the fluidity of concrete mixture, or reduce the amount of unit cement, saving cement. Materials are divided into many categories, such as lignin sulfates; polycyclic aromatic salts; water-soluble resin sulfates. According to the water-reducing agent, water reduction and enhanced ability are divided into a variety of ordinary water-reducing agents (also known as plasticizers, with a water reduction rate not less than 8%, represented by lignin sulfonate), efficient water-reducing agents (also known as superplasticizer, water reduction rate not less than 14%, including naphthalene system, dense amine system, amino sulfonate system, aliphatic system, etc.) and high-performance water reducer (water reduction rate is not less than 25%, represented by polycarboxylic acid system water reducing agent), and respectively divided into early strong type, standard type, and slow setting type. According to the chemical composition, it can also be divided into a variety of categories: lignin sulfonate water reducing agent, naphthalene high efficient water reducing agent, melamine high efficient water reducing agent, amino sulfonate high efficient water reducing agent, fatty acid high water reducing agent, polycarboxylate high efficient water reducing agent.
Main uses of water reducer The water-reducing agent mainly has a dispersion effect, lubrication effect, steric hindrance effect, and slow release effect of grafted copolymerization branch chain. The following is to talk about dispersion and lubrication. First is the dispersion of cement water mixing; due to the hydration of cement particles, cement particles surface double electric layer structure, making the solvation water film, and cement particles surface with the opposite charge association between cement particles, making cement slurry flocculation structure, make 10%~30% of the mixed water is wrapped in cement particles, can not participate in the free flow and lubrication, thus affecting the fluidity of the concrete mix. When adding water reducing agent, because the water reducer molecules can directional adsorption on cement particles surface, the cement particles surface with the same charge (usually negative charge), form electrostatic exclusion, make cement particles dispersed, flocculation structure disintegration, the release is wrapped part of the water, participate in flow, thus effectively increase the fluidity of concrete mix. The second is lubrication: the hydrophilic base in the water-reducing agent is very strong, so the water-reducing agent adsorption film on the surface of cement particles can form a stable solvated water film with water molecules; this layer of water film has a good lubrication effect, can effectively reduce the sliding resistance between cement particles, so that the concrete fluidity is further improved.
Price of water reducer The different price of water reducer purity is also different. The market price of water reducer is in the process of dynamic change. The price of water reducer can be found on our company's official website. If you need it, you can ask us at any time.
