Construction Industry Chemical

Product Details:

Carbohydrates of low-molecular weight, dextrins are obtained by the hydrolysis of glycogen or starch. Essentially dextrins are long chains of D-glucose units bridged by glycosidic bonds.

Dextrins are available in multiple forms, as white, yellow or brown powders that are vary in their degree of solubility. Most dextrins yield optically active solutions of low viscosity. White and yellow dextrins manufactured from starch with little to no acid are termed as ‘British Gum’.

Yellow dextrins find application as water-soluble glues and additives in sand casting used in the construction industry.

Areas of application:

• Construction industry – castings and glues.
• Paper industry – adhesives.
• Printing industry – thickeners.

Qualities:

• Adhesive
• Thickener
• Texturizer

Product Details:

Modern construction uses calcite in the form of limestone and marble to produce cement and concrete. These materials are easily mixed, transported and placed in the form of a slurry that will harden into a durable construction material.

Primarily consisting of carbonate, Calcite is calcium carbonate’s most stable polymorph. Other polymorphs include aragonite and vaterite.

Calcite occurs in several forms besides the regular structure, as fibrous, granular, lamellar or compact forms.

Today, Calcite is used in construction, soil remediation, soil stabilization and concrete repair.

Areas of application:

• Construction industry

Qualities:

• High stability
• Lustrous
