How Concrete is Made: Additives. Additives are solid or liquid chemical substances that can be added to readymix concrete before or during preparation. Most commonly used additives either improve a hardened concrete's durability or reduce a concrete's water content in an effort to shorten setting times.

An Overview. 1. Normal concrete that is supposed to keep water out of a structure must be 'waterproofed' as separate, distinct, additional, design and construction functions. 2. Where the absorbed water contains aggressive soluble salts and acids, all concrete will always corrode, including all reinforced concrete.
additives for highperformance and speciality concretes The performance of conventional concrete additives is limited when it comes to manufacturing highdensity, highdurability concretes for, say, thinwalled façade elements or the ultimate in fairface finishes.

Nov 19, 2018· The durability of these solid constructions can be further enhanced by using concrete additives to the basic building materials. Though it is not mandatory to use these additives in the concrete; lots of builders and engineers prefer these materials for adding more stability to .
Durability of Concrete Floors. When installed properly, concrete is one of the most durable materials on earth. Properly maintained, your floor should last a lifetime. Few flooring materials have the longevity of concrete. Carpet, tile and even wood floors eventually need replacement, which uses up resources and creates disposal problems.
Concrete Imerys minerals for reduced porosity and cracking in concrete Imerys minerals make excellent multifunctional additives in concrete where they reduce porosity and efflorescence, increase cured compressive strength and viscosity control, and prevent cracking.
