What is a good reducing agent


Faster setting times and greater strengths during the early hydration phase are provided by this accelerating feature, which enables finishing operations to be completed on schedule, especially at lower temperatures. As can be seen, using silica fume and fly ash in concrete reduces concrete's water absorption capacity. Lithium is the strongest reducing agent because of its lower reduction potential (i.e., it has a lower tendency to acquire electrons.) Good reducing agents include active metals, such as sodium, magnesium, aluminum, and zinc, which have relatively small ionization energies and low electro-negativities. Metal hydrides, such as NaH, CaH2, and LiAlH4, which formally contain the H- ion, are also good reducing agents. Good reducing agents tend to consist of atoms with low electronegativity, the ability of an atom or molecule to attract bonding electrons1, and relatively small ionization energies serve as good reducing agents too. In the H2O Bond dissociation enthalpy of O,–H is more than S – H bond of H2S. Therefore, H2S is a better-reducing agent than H2O. Since many of the strongest reducing agents react with water to generate products that are also flammable, water cannot be used to put out fires of strong reducing agents, especially metals. Members of this group are often included in explosive mixtures. Out of various substances which can be used as reducing agents, carbon in the form of coal is the cheapest and most abundantly used reducing agent. Water reducers do essentially that: reduce the mixing water required to obtain a given slump. This can result in a reduction of the water-cementitious ratio (w/c ratio), which leads to increased strength and more durable concrete. High-range water-reducing admixture is used to produce high-strength concrete to reduce the cross-section of compression members in high-rise buildings, improve the durability of concrete in aggressive environments, and many more applications.
