    Abstract: A hardened cementitious composite produced using conventional mixing techniques, including a microsilica-cement mixture and randomly distributed discontinuous polyamide fibers is described. Other mix ingredients used in forming the composite are superplasticizer, water and possibly aggregates and fly ash substituting for part of the Portland cement. The microsilica particles are essential in dispersing the fibers during the regular mixing, and in enhancing the fiber-cement interfacial bond. Microsilica also reduces the alkalinity of the matrix and helps in increasing the durability of polyamide fibers in the alkaline environment of cement. With their close spacing and superior bond to the matrix of the composite, the polyamide fibers are highly effective in increasing the ultimate tensile and flexural strength and in improving the ductility and toughness of the material.

    Abstract translation: 描述了使用常规混合技术制备的硬化水泥质复合材料，包括微硅粉 - 水泥混合物和随机分布的不连续聚酰胺纤维。 用于形成复合材料的其他混合成分是超增塑剂，水和可能的聚集体和飞灰，代替部分波特兰水泥。 微米粉颗粒在常规混合期间分散纤维是必需的，并且在增强纤维 - 水泥界面粘合中是必需的。 微硅粉还降低了基体的碱度，有助于提高聚酰胺纤维在碱性环境下的耐久性。 由于它们与复合材料的基体密切间隔和优异的结合，聚酰胺纤维在提高极限拉伸和弯曲强度以及提高材料的延展性和韧性方面是非常有效的。

    Abstract: Shape-memory fibers are incorporated into a metal matrix material with a level of fiber-to-matrix bonding so that upon localized failure of matrix under load, the strains in fibers debond them from the matrix to the extent that fibers do not all rupture at the location of matrix failure. The pull-out process of fibers ruptured away from the matrix failure location provides the composite material with substantially increased ductility and energy absorption capacity after localized failure of the matrix. Pre-tensioning of shape-memory fibers impose sustained stresses on matrix which enhance the strength and energy absorption capacity of the composite material. The shape-memory fibers may be incorporated into a metal matrix at their end so that fibers pull out from the matrix under load and provide an energy-absorbing assembly.

    Abstract: Pulp fibers derived from wood or non-wood plants or recycled paper products, which are 0.1-30 mm long and about 0.001-0.1 mm in equivalent diameter, are individualized by mechanical action, blended with at least one of the dry ingredients of the cement-based material and then mixed with the remaining ingredients of conventional cement-based mixtures using conventional mixing equipment for effectively improving fresh and hardened properties of cement-based materials. Dispersion is achieved by individualizing the plant pulp fibers by mechanical action, and further by blending the individualized fibers with at least one of the dry ingredients of the mix and then with the remaining ingredients of the cement-based material, with fibers added at relatively low dosages of about 0.3-30 kg per cubic meter. The affinity of plant pulp fibers for water facilitates their dispersion in conventional cement-based mixtures. Fresh mixtures of cement-based materials incorporating the dispersed individualized plant pulp fibers possess desirable workability, resistance to segregation and bleeding, pumpability, finishability, and reduced rebound when pneumatically applied. Hardened cement-based materials incorporating the dispersed individualized plant pulp fibers provide improved crack resistance, toughness characteristics, impact resistance, fatigue life, abrasion resistance, and other mechanical, physical and durability characteristics. Plain and reinforced concrete and shotcrete as well as precast and cast-in-place concrete, plaster and stucco, mortar, grout and flowable fill are examples of cement-based materials which can benefit from the improvements in fresh and hardened material properties rendered by dispersed plant pulp fibers.

    Abstract: A CO.sub.2 pre-curing period is used prior to accelerated (steam or high-pressure steam) curing of cement and concrete products in order to: (1) prepare the products to withstand the high temperature and vapor pressure in the accelerated curing environment without microcracking and damage; and (2) incorporate the advantages of carbonation reactions in terms of dimensional stability, chemical stability, increased strength and hardness, and improved abrasion resistance into cement and concrete products without substantially modifying the conventional procedures of accelerated curing. Depending on the moisture content of the product, the invention may accomplish CO.sub.2 pre-curing by first drying the product (e.g. at slightly elevated temperature) and then expose it to a carbon dioxide-rich environment. Vigorous reactions of cement paste in the presence of carbon dioxide provide the products with enhanced strength, integrity and chemical and dimensional stability in a relatively short time period. Subsequent accelerated curing, even at reduced time periods (with less energy and cost consumptions) would produce higher performance characteristics than achievable with the conventional pre-setting period followed by accelerated curing of cement and concrete products.

    Abstract: Pulp fibers derived from wood or non-wood plants or recycled paper products are individualized and dispersed in water, and mixed into cement-based mixtures using conventional mixing procedures at relatively low dosages of about 0.3-30 kg of fiber per cubic meter of concrete. Once individualized, the affinity of plant pulp fibers for water facilitates their dispersion in normal cement-based mixtures. Fresh cement-based materials incorporating the dispersed individualized plant pulp fibers provide desirable workability, resistance to segregation and bleeding, pumpability, finishability, and reduced rebound when pneumatically applied. Hardened cement-based materials incorporating the dispersed individualized plant pulp fibers provide improvements in crack resistance, toughness, impact resistance, fatigue life, abrasion resistance, and other mechanical, physical and durability characteristics.
