How do you identify a reducing agent


Increases the workability (assuming the amount of free water remains constant), reduces the water permeability (due to less water being used), reduces the diffusivity of aggressive agents in the concrete, and improves the durability of concrete. Gives a better finish to surfaces (due to all of the above). Break the reaction down into a net ionic equation and then into half-reactions. The substance that loses electrons is being oxidized and is the reducing agent. The substance that gains electrons is being reduced and is the oxidizing agent. A strong reducing agent is a molecule that donates electrons very easily.

In contrast, a weak reducing agent is a molecule that donates electrons less easily. Some common strong reducing agents include lithium aluminum hydride (LiAlH4) and sodium borohydride (NaBH4). The definition of reducing agents is easy: A reducing agent is a substance oxidized by donating electrons. This is why reducing agents are also called electron donors. They help reduce a substance in a reduction reaction.

The opposite of the reducing agent is the oxidizing agent or electron acceptor. The main difference between plasticizers and superplasticizers is that plasticizers can reduce the need for water by 5-15%, whereas superplasticizers can reduce the need for water by 30%. ECLIPSE® is a liquid admixture that dramatically reduces drying shrinkage and the potential for cracking and curling in full or partially-restrained concrete flooring and paving. ECLIPSE® products reduce the surface tension of pore water. Retarding admixtures are used to slow down the speed of the reaction between cement and water by slowing down the growth of the hydration products or reducing the water penetration rate to the cement particles. By this, concrete stays workable for longer than it would otherwise have been.
