The waterproofing agent is an admixture formulated from chemical raw materials that can improve cement concrete and mortar’s water impermeability. When the waterproofing agent is used, it is usually mixed into cement concrete or cement mortar proportionally (sometimes painted on the surface and penetrates the cement concrete or cement mortar) to form waterproof concrete or […]
1. Calcium oxide concrete expanding agent Calcium oxide concrete expanding agent uses CaO as the expansion source and is made from ordinary lime and stearic acid ground together in a particular proportion. Stearic acid is added to lime (calcium oxide) during grinding. On the one hand, it acts as a grinding aid. On the other […]
CSA expanding agent CSA expanding agent is made of bauxite, limestone, and gypsum as the primary raw materials and is calcined at around 1300°C and then ground. The dosage of CSA expanding agent is generally 8% to 10% of cement; the expansion rate of cement mortar is 0.5%; the expanding rate of pure slurry is […]
A concrete expanding agent is an admixture mixed with cement and water that undergoes a hydration reaction to form ettringite or calcium hydroxide, causing the concrete to expand to a specific volume. Expanding agents into ordinary concrete can prepare shrinkage-compensating concrete and self-stressing concrete, so expansion agents are widely used. The essence of concrete water […]
Big 5 Global, is set to take place at Dubai World Trade Centre from 4 – 7 December 2023. With registrations open for participants who wish to attend the annual gathering of the global construction industry, the event aims to host 2,200+ exhibitors and 68,000+ attendees from more than 150 countries for four days of […]
Hydrophobic agents are a class of admixtures that prevent moisture from entering the mortar while also keeping the mortar open to allow water vapor to diffuse. Water repellent includes three product series: fatty acid metal salts, silanes, and special hydrophobe re-dispersible polymer powders. The unit cost of the fatty acid metal salt product series is […]
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 […]
