Calcium aluminates - Wikipedia
Calcium aluminates are a range of materials [2] obtained by heating calcium oxide and aluminium oxide together at high temperatures. They are encountered in the manufacture of refractories and cements .
Calcium aluminate cements - Wikipedia
The cement is made by fusing together a mixture of a calcium-bearing material (normally calcium oxide from limestone) and an aluminium-bearing material (normally bauxite for general purposes, or refined alumina for white and refractory cements).
Calcium Aluminate | Formula, Properties & Application
Calcium aluminate, a chemical compound commonly used in construction and industry, possesses unique physical and chemical properties that set it apart from other materials. It is particularly prominent in high-temperature and refractory applications due to …
Calcium Aluminate - an overview | ScienceDirect Topics
Calcium aluminate cements are known for their rapid strength gain, especially at low temperatures, superior durability across several categories and high temperature resistance. Their ability to consume water rapidly during hydration makes them a preferred component in building chemistry applications as this contributes to construction expediency.
铝酸钙 CAS#: 12042-68-1 - ChemicalBook
铝酸钙是一系列由氧化钙和氧化铝在高温下烧结而成的无机化合物，由于其硬度大、熔点低的物理性质，主要用途用于工业。 在冶金行业铝酸钙作为洁净剂，铝酸钙精炼渣脱硫效率可达百分之45.83，这为精炼洁净钢创造了良好的条件。 铝酸钙粉与盐酸反应，可一步制得聚合氯化铝。 生产时，先将反应池中加水，开启搅拌浆，然后定量加入盐酸，稀释至要求浓度后，再缓慢加入铝酸钙粉进行反应。 反应过程中，池内温度会逐渐升高。 超过110℃时，可适量加水抑制，使反应 …

Structural, electronic, and mechanical properties of calcium aluminate ...
2020年12月20日 · Calcium aluminate cements (CACs) have attracted much attention due to their potential applications in severe environments. Up to now, their structural, electronic, and mechanical properties have not been fully determined yet. This study shed light on these properties by means of first-principles density functional theory.
The Phases and Structure of Calcium Aluminate Cements (CACs) - AZoM.com
2002年9月11日 · On the other hand, calcium aluminate cements (CACs) have reactive phases that constitute lime-alumina compounds. CACs are also known as high-alumina cements (HACs) or aluminous cements, which resulted out of a drive to create cements that are resistant to sulfate.
