摘要： Compositions useful for the preparation of lightweight, high strength wallboards, and methods of making same are disclosed. The composition includes a slurry of calcium sulfate hemihydrate (stucco), water, starch, and a foam. The foam acts to provide large bubbles within the core slurry, thereby lightening the weight of the wallboard. The composition and method provide wallboards having lighter weights compared to standard wallboard, increased core strength, and increased paper-to-core bonding.

摘要： The present invention is of a cementitious composition containing OPC, calcined gypsum, a source of amorphous silica and a source of amorphous alumina. The ratio of calcium sulfate hemihydrate to OPC is 0.7:1.0 to 1.4:1.0, the ratio of amorphous silica and amorphous alumina to OPC is 0.26:1.0 to 0.4:1.0, and the ratio of amorphous alumina to amorphous silica is 0.3:1.0 to 1.5:1.0. The cementitious composition, by itself and mixed with aggregates, is fast-setting and exhibits good early compressive strength and very high compressive strength after hydration. Despite the high content of calcium sulfate relative to prior art OPC formulations, the cementitious composition according to the present invention is essentially waterproof and exhibits excellent strength characteristics, even after 2 years under water. The use of calcined gypsum in place of alumina cement or even OPC is of great economic advantage, and in addition, provides the cementitious composition with quick-setting characteristics.
摘要翻译：本发明是含有OPC，煅烧石膏，无定形二氧化硅源和无定形氧化铝源的水泥组合物。硫酸钙半水合物与OPC的比例为0.7:1.0至1.4:1.0，无定形二氧化硅和无定形氧化铝与OPC的比例为0.26:1.0至0.4:1.0，无定形氧化铝与无定形二氧化硅的比例为0.3:1.0至 1.5：1.0。水泥组合物本身并且与聚集体混合，是快速凝固的，并且在水合后表现出良好的早期抗压强度和非常高的抗压强度。尽管相对于现有技术的OPC制剂，硫酸钙的含量高，但是根据本发明的水泥组合物基本上是防水的，并且即使在水下2年后也显示出优异的强度特性。使用煅烧石膏代替氧化铝水泥甚至OPC具有很大的经济优势，另外为水泥组合物提供快速凝固特性。
