摘要： Microparticles having crystalline needle or rod-shaped structures of, for example, an ettringite mineral grown and attached radially from their surface. A method including nucleating and growing crystalline needles/rods from the surface of a particle in the presence of a solution of calcium, sulfur, and aluminum such as calcium sulfoaluminate, lime and calcium sulfate is described. One example is the radial growth of ettringite needles on the surface of fly ash particles in calcium sulfoaluminate-based cement paste and concrete.

摘要： Synthetic fibers, such as polypropylene fibers, are mixed in a shrinkage compensating concrete to provide restraint in lieu of conventional steel reinforcement used in a shrinkage compensating concrete. While the synthetic fibers have a low elastic modulus and low strength, they act to restrain expansion of the concrete in the same way that conventional steel rebar does. In addition, only a small amount of the synthetic fibers are needed to restrain the expansion. As a result, shrinkage compensating concrete can be used in more varied applications, and can be provided more quickly, easily and inexpensively. Construction time requirements and expenses of concrete structures are correspondingly reduced.

摘要： An apparatus and method for testing brittle materials in tension includes a gripping sleeve of a viscous yieldable material placed over a specimen and a pulling sleeve adapted for placement over the gripping sleeve and for attachment to a testing apparatus. The pulling sleeve imparts load to the gripping sleeve which in turn imparts load to the specimen. Elements are provided to minimize elastic rebound.

摘要： An improved expansive cement and method of forming same. An expansive clinker containing a stable calcium alumino sulfate compound is separately ground to a selected surface area greater than about 4600 sq. cm/gm. The ground expansive clinker is then blended with a ground cement clinker and with gypsum to form the expansive cement. The expansive cement formed in accordance with the present invention requires less of the expansive clinker than expansive cements known in the art to achieve the same magnitude of expansion.

摘要： A shrinkage compensating cement exceeding the ASTM standard specification limiting 28 day expansion to 115% of the 7 day expansion. 28 day expansions of 120-200% are contemplated. The expansion takes place over an extended period of time, to better offset the shrinkage occurring as the concrete dries. The development of tensile stresses in the concrete is reduced and also is delayed, allowing more time for the tensile strength of the concrete to increase as the concrete dries. Shrinkage cracking is consequently significantly reduced.
摘要翻译：超过ASTM标准规范的收缩补偿水泥限制了28天膨胀到7天膨胀的115％。预计28天扩张120-200％。膨胀发生在较长时间内，以更好地抵消混凝土干燥时发生的收缩。混凝土中的拉伸应力的发展减少并且延迟，允许混凝土的拉伸强度随着混凝土干燥而增加的时间更多。收缩裂缝因此显着降低。
