Tin dioxide

Tin dioxide (SnO2), an important type of semiconductor with a wide band gap (Eg = 3.6 eV), exhibits excellent optical, electrical, and chemical properties and high thermal stability. In recent years, doped SnO2 and SnO2- based materials, such as Sb-doped SnO2, Mn-doped SnO2, Zn2SnO4, Cd2SnO4, and so on, have been extensively studied due to their special optical and electrical properties. During the past few years, these materials have been prepared by many techniques such as sol-gel, simple ther

What is foam concrete

Foam concrete, also known as lightweight aerated concrete, variable density concrete, cellular concrete, and lightweight or ultra-lightweight concrete, is a cementitious material with a minimum of 20% volume of mechanically entrained foam in the plastic mortar. As mostly no coarse aggregate is used to produce foam concrete, the correct term would be indeed mortar instead of concrete. Sometimes it may also be called "foamed cement" or "foam cement" because of a mixture of only cement and foam wit


The impact of calcium stearate on characteristics of concrete

Moisture and aggressive ions transferring into concrete harm the durability of reinforced concrete structures. To tackle this problem, damp-proofing admixtures, like calcium stearate, can be incorporated into the concrete mixture design to restrict water and aggressive ions’ ingress into concrete. Calcium stearate is a damp-proofing admixture providing a water-repellent layer along the capillary pores. As a result, it can reduce the permeability of concrete under non-hydrostatic conditions.
