摘要： This invention relates to a formulation with the addition of low density additives of volcanic ash, hollow ceramic microspheres or a combination of microspheres and volcanic ash or other low density additives into cementitious cellulose fiber reinforced building materials. This formulation is advantageously lightweight or low density compared as compared to current fiber cement products without the increased moisture expansion and freeze-thaw degradation usually associated with the addition of lightweight inorganic materials to fiber cement mixes. The low density additives also give the material improved thermal dimensional stability.

摘要： A process for binding porous-rock particles with cement, wherein the rock is saturated in water prior to mixing with the cement. The saturation step causes water to fill the voids in the porous structure of the rock such that, during mixing of the wet rock with cement, cement particles adhere to the surface of the rock but are mostly precluded from reaching void spaces in the rock. As a result of this procedure, the interstitial water is available from within the rock for the cement hydration process, thereby providing a more uniform curing step than otherwise available, and a greater proportion of the cement is appropriately placed on the outer surface of the particles for bonding. The resulting aggregate is stronger than obtained by conventional mixing processes. In addition, because of the voids left in the composite after the cement has cured and the interstitial water has been either used by the hydration process or has evaporated, the material also exhibits improved insulating properties.

摘要翻译： 一种用水泥粘合多孔岩石颗粒的方法，其中岩石在与水泥混合之前在水中饱和。 饱和步骤使水填充岩石的多孔结构中的空隙，使得在湿岩石与水泥混合期间，水泥颗粒粘附到岩石的表面，但是大部分排除在岩石中的空隙空间之外。 作为该过程的结果，间隙水可从岩石内获得用于水泥水化过程，从而提供比其它可获得的更均匀的固化步骤，并且将较大比例的水泥适当地放置在颗粒的外表面上 用于粘合。 所得聚集体比通过常规混合方法获得的更强。 另外，由于在水泥固化后复合材料中留下的空隙和间隙水已被水化过程使用或已经蒸发，所以材料也具有改善的绝缘性能。

摘要： A constructional finished wallboard is formed of a mixture including 50 to 65 wt. % of dried shirasu, 30 to 40 wt. % of a plaster component, 3 to 10 wt. % of a clay component, 5 to 10 wt. % of shirasu balloons, 0.8 to 2 wt. % of a bond reinforcing component, 0.01 to 3 wt. % of a color pigment, and 1 to 5 wt. % of fibers for plaster. In preparing the wallboard, after preparing the mixture, an appropriate amount of water is added to the mixture to mix together, which is applied onto a substrate. Then, the surface of the mixture on the substrate is finished, followed by drying to thereby form the constructional finished board.
