    摘要： A fiber-reinforced and starch-based composition can be prepared by combining two fractions. The first fraction can include a gelatinized starch, water, and fibers, wherein the fibers are substantially homogenously mixed with the starch in an amount sufficient to structurally reinforce the mechanical characteristics of the starch-based composition. The second fraction is then combined with the first fraction, wherein the second fraction can include non-gelatinized starch, non-volatile plasticizer, and a water-resistant polymer. The composition is mixed so as to form a thermoplastic composition being capable of expanding when rapidly heated to above the boiling point of water and the softening point of the plasticized starch. Additionally, fiber-reinforced articles can be prepared from a method of processing the starch-based compositions. Such a method includes introducing the fiber-reinforced starch-based composition into a mold, and molding the composition into a fiber-reinforced article.

    摘要： A concrete composition having a 28-day design compressive strength of 4000 psi and a slump of about 5 inches is optimized to have high workability and a high strength to cement ratio. The concrete composition contains about 375 pounds per cubic yard hydraulic cement (e.g., Portland cement), about 113 pounds per cubic yard pozzolanic material (e.g., Type C fly ash), about 1735 pounds per cubic yard fine aggregate (e.g., FA-2 sand), about 1434 pounds per cubic yard coarse aggregate (e.g., CA-11 state rock, ¾ inch), and about 294 pounds per cubic yard water (e.g., potable water). Workability and strength to cement ratio were increased compared to one or more preexisting concrete compositions having the same 28-day design compressive strength and similar slump by optimizing the ratio of fine aggregate to coarse aggregate. The concrete composition is further characterized by high cohesiveness, resulting in relatively little or no segregation or bleeding.

    摘要： A molded cementitious architectural product for use in building construction has a cementitious body made of a molded cementitious material, the surface of which is polished (i.e., burnished) to better resemble natural stone. The polished surface is formed by exposing a portion of the molded cementitious material while in a green condition, more particularly after initial set but before final hardening of the hydraulic cement binder, and burnishing the surface before final hardening. Burnishing the surface of the green cementitious material before final hardening aligns the cement particles at the surface and seals the surface. The inclusion of an organic polymer binder within the cementitious material, such as an acrylic or latex polymer, assists in creating a polished surface resembling natural polished stone. The extent of cement hydration may be determined by monitoring the temperature of the cementitious material within the mold. Hydration may be slowed by quenching the molded green cementitious material with water to extend the window of time within which burnishing may be carried out before reaching final hardening.

    摘要翻译： 用于建筑施工的模制水泥建筑产品具有由模制的水泥质材料制成的水泥体，其表面被抛光（即抛光）以更好地类似于天然石材。 抛光表面通过在处于绿色条件下暴露一部分模制的水泥质材料而形成，更特别是在初始凝固之后，但在水硬性水泥粘合剂的最终硬化之前，以及在最终硬化之前抛光表面。 在最终硬化之前，将绿色水泥质材料的表面抛光，将水泥颗粒对准表面并密封表面。 在水泥质材料（例如丙烯酸或胶乳聚合物）中包含有机聚合物粘合剂有助于产生类似天然抛光石的抛光表面。 水泥水化程度可以通过监测模具内的水泥质材料的温度来确定。 通过用水淬火模制的绿色水泥质材料可以减缓水化，以延长可以在达到最终硬化之前进行抛光的时间窗口。
