What is BASF for an admixture?
In its ongoing leadership role in the concrete industry, BASF unveils Master X-Seed® 55, a first-of-its-kind, strength-enhancing admixture that improves both early- and late-age strength development in concrete.
What additives can be used in cement?
Depending on the application of the cement, a wide variety of additives can be incorporated. These include accelerators, retarders, dispersants, extenders, weighting agents, gels, foamers, and fluid loss additives.
What are concrete additives?
Concrete additives are added to the mixture of water cement and aggregate in small quantities to increase the durability of the concrete, to fix concrete behavior and to control setting or hardening. These additives are supplied in ready-to-use liquid form and are added to the concrete at the plant or at the jobsite.
What is construction additives?
Construction chemicals are chemical formulations used with cement, concrete or other construction materials at the time of construction to hold the construction material together. The global construction chemical market can be categorised as: Concrete admixtures. Asphalt modifiers. Adhesives and sealants.
What produces BASF?
BASF produces a wide range of chemicals such as solvents, amines, resins, glues, electronic-grade chemicals, industrial gases, basic petrochemicals, and inorganic chemicals. The most important customers for this segment are the pharmaceutical, construction, textile, and automotive industries.
How do you mix concrete admixtures?
An admixture is a substance which can be added to concrete to achieve or modify its properties. Admixtures are added to the concrete, in addition to cement, water and aggregate, typically immediately before or during the mixing process.
What is added to concrete to make it set slower?
Retarding admixtures are used to slow the rate of setting of concrete. By slowing the initial setting time, the concrete mixture can stay in its fresh mix state longer before it gets to its hardened form. Use of retarders is beneficial for: Complex concrete placement or grouting.
Why are additives used in concrete?
Types of Concrete Additives The additives are added to a water-cement mixture to increase the life of the concrete, control setting, and hardening and fix the general concrete behavior.
What is the purpose of additives in concrete?
Admixtures are added to the concrete, in addition to cement, water and aggregate, typically immediately before or during the mixing process. Admixtures can be used to reduce the cost of building with concrete, or to ensure certain required properties or quality of the cured concrete.
What is the difference between additive and admixture?
The main difference between additives and admixtures is that additives are added to cement during manufacturing to get new properties for cement whereas admixtures are added to concrete mixtures while mixing to get new properties.
What chemicals do BASF sell?
The major products include MDI (diphenylmethane diisocyanate), TDI (toluene diisocyanate), caprolactam, adipic acid, polyamide 6 and 6.6, ammonia, nitric acid, sulfur and chlorine products, inorganic salts, urea, melamine, glues and impregnating resins.
Why do we need to use BASF additives?
To achieve groundbreaking formulations providing outstanding workability and physical properties, your system needs advanced raw materials. BASF offers a broad range of powder and liquid additives which enable you to formulate innovative products.
How are fluid loss additives used in cement?
Cement slurries can lose water to permeable zones causing a number of problems, such as insufficient mud displacement, high viscosity, unwanted change of set-time, and lack of final compressive strength. Fluid loss additives reduce water loss through the cement filter cake, which makes them especially useful in squeeze cementing.
What kind of additives are used in construction?
BASF offers a broad range of powder and liquid additives which enable you to formulate innovative products. The properties of construction materials, such as dry mortars and prefabricated materials, are influenced by the quality of local raw materials.
