    摘要: A refractory includes a cement, a binder and a matrix. The matrix comprises both stainless steel fibers and organic fibers. The refractory can be easily cast, without additional steel reinforcement, into large fire wall 16 panels 10 capable of meeting the requirements of testing conducted in accordance with ASTM E-119, Standard Test Methods for Fire Tests of Building Construction and Materials in support of IEEE Std. 979-1994, Guide for Substation Fire Protection. The fire wall 16 assembly withstood the fire endurance test without passage of flame and gases hot enough to ignite cotton waste during a four-hour fire exposure. The assembly also withstood a 45? water stream for five minutes immediately following the four-hour fire exposure period. This is a stringent mechanical requirement, as all fire walls 16 must maintain their integrity before, during and after a fire, per the Universal Building Code=s definition of a true fire wall 16.

    摘要: Provided is a protective concrete for weaken the intensity of proton radiation, and it is prepared by mixing 525# cement 500-700 Kg; barite sand 1000-1400 kg, barite stone 1500-1800 Kg, lead powder 180-200 Kg and water 170-180 Kg. The barite that can absorb the proton radiation is used, so the present concrete is much better than conventional concretes in weakening the proton radiation, and 1.5 m-thick wall without lead plates which is prepared with the present concrete can achieve the same effect on weakening the proton radiation with a conventional 2 m-thick wall covering with lead plates.

    摘要: According to various embodiments, gas-generating additives for use in a cement composition comprise: a gas-generating material at least partially coated with a mixture comprising a fatty acid ester of sorbitan, glycerol, or pentaerythritol and having a shelf life of about 12 months or greater. The gas-generating additives may also include a C8-C18 hydrocarbon. In more embodiments, cement compositions comprise: a gas-generating material at least partially coated with a mixture comprising a fatty acid ester of sorbitan, glycerol, or pentaerythritol and a C8-C18 hydrocarbon for increasing a shelf life of the gas-generating material. In yet more embodiments, cement compositions comprise: a cement; a fluid for making the cement composition pumpable; a hydrogen-generating material at least partially coated with a mixture for delaying a hydrogen-generating reaction, the mixture comprising sorbitan monooleate and an isoparaffin.
