Accelerating agent refers to a setting regulating agent that can speed up the setting and hardening of concrete and mortar. According to the chemical composition of their compounds, accelerated agents can be divided into two categories: inorganic and organic. The leading accelerating agent in China is primarily inorganic salts, and the main component is sodium […]
The 15th edition of the China HomeLife Dubai event is scheduled to take place from 19 to 21 December at the Dubai World Trade Centre The 15th edition of China HomeLife Dubai is back, bigger and better than ever. Mark your calendars for 19 to 21 December, 2023, as this prestigious event returns to its […]
A water-reducing agent is an admixture that can reduce the necessary unit water consumption in concrete, meet the specified consistency requirements, and improve the workability of concrete. The main functions of water-reducing agents are as follows: increasing hydration efficiency, reducing unit water consumption, increasing strength, and saving cement consumption; improving the workability of unsolidified concrete […]
There are many types of concrete admixtures, which can be divided into the following categories according to their chemical composition: inorganic admixtures, organic admixtures, and composite admixtures. Inorganic admixtures are mainly electrolyte salts; organic admixtures are mostly surface-active substances and some high molecular polymers, organic compounds, and double salts. Surfactant admixtures can be divided into […]
Starch ether is a polyacrylamide compound extracted from natural plants. It has the same chemical structure and similar properties as cellulose ether. Starch ether is mainly used in construction mortars. They can affect the consistency of mortars based on gypsum, cement, and lime and change mortars’ workability and sagging resistance. Starch ether is usually combined with non-modified and modified cellulose […]
Polyvinyl alcohol powder is a type of water-soluble film-forming adhesive substance. Its products are now widely used in some dry-mixed mortar products. It provides a relatively cheap adhesive material for powdery and paste putties. Adding Polyvinyl alcohol powder to dry-mixed mortar products like redispersible polymer powder increases its bonding strength, but its comprehensive performance is far from comparable […]
In dry-mixed mortar products, two cementitious material systems, cement and redispersible polymer powder are an ideal match. Combining the two in dry-mixed mortar products achieves significant synergistic effects. Any cementing material used alone can have unattainable properties that allow polymer-modified mortar to be used on various special occasions and have obvious advantages in quality control, construction operations, storage, and […]
Redispersible Polymer powder is usually white, but there are also a few other colors. Its main ingredients are as follows: Polymer resin: Located at the core of polymer powder particles, it is also the main component of Redispersible Polymer powder, such as ethylene vinyl acetate (EVA), polyacrylate (PAE), etc. Additives (internal): Play the role of modifying the resin. […]
There are two systems of cementitious materials, namely inorganic cementitious materials and organic cementitious materials. Inorganic cementitious materials such as cement can bond aggregates to form a rigid framework, while organic cementitious materials can endow the rigid framework with cohesion properties and dynamic behavior, as well as improved bonding to difficult-to-bond substrates. Synthetic polymer emulsions […]
1. Acrylate emulsion Acrylate is the general term for acrylic acid and its homolog esters. Mainly includes methyl acrylate, ethyl acrylate, butyl acrylate, methyl methacrylate, and butyl methacrylate. Acrylate can be self-polymerized or copolymerized with other monomers and is the primary raw material for producing acrylate emulsion. Acrylate emulsion is an emulsion prepared by acrylate monomers […]
