    • There is disclosed a method of selecting, in real time, a soil stabilizing protocol for clay-bearing soils occurring in construction sites. The method includes the steps of: obtaining soil conductivity data values at locations within a defined site without disturbing the surface of the soil; correlating the soil conductivity data values with corresponding estimates of soluble sulfate levels; recommending a calcium-based soil stabilizing protocol if the estimated level of soluble sulfates is less than a predetermined threshold; and performing a laboratory analysis of soil samples from selected portions of the defined site when the estimated soluble sulfate concentration equals or exceeds the predetermined threshold.
    • 公开了一种实时选择在施工现场发生的粘土土壤的土壤稳定方案的方法。 该方法包括以下步骤:在限定位置的位置获得土壤电导率数据值,而不会干扰土壤表面; 将土壤电导率数据值与可溶性硫酸盐水平的相应估计值相关联; 如果估计的可溶性硫酸盐水平低于预定阈值,则建议钙基土壤稳定方案; 并且当估计的可溶性硫酸盐浓度等于或超过预定阈值时,对所定义部位的选定部分进行土壤样品的实验室分析。

    • A composition for a pumpable lime slurry which is adapted for use as a replacement for caustic solutions is formed by combining a dispersing agent in lime and water to form an aqueous slurry. The amount of lime used is between 35 to 55% by weight of the slurry. The dispersing agent, which is an anionic polyelectrolyte, such as polyacrylic, polycarboxylic acids and alkali metal salts thereof, is added in the an amount between 0.1 to 3% by weight of the lime. To this is added an alkali metal hydroxide of 0.1 to 1.5% by weight of lime. The order of addition of the alkali metal hydroxide is important. The later addition of the alkali metal hydroxide results in a decreased viscosity so that a lower amount of dispersing agent is required.
    • 通过将石灰和水中的分散剂组合以形成水性浆料,形成适用于替代苛性碱溶液的可泵送石灰浆料的组合物。 所使用的石灰的量为浆料的35至55重量%。 作为阴离子聚电解质的分散剂,例如聚丙烯酸,多元羧酸及其碱金属盐,其添加量为石灰重量的0.1〜3%。 向其中加入0.1至1.5重量%的石灰的碱金属氢氧化物。 加入碱金属氢氧化物的顺序是重要的。 碱金属氢氧化物的后续添加导致粘度降低,从而需要较低量的分散剂。

    • A method and apparatus for providing a continuous product stream of lime slurry to a job site which is located remote from a permanent lime production plant utilizes a primary and auxiliary tank which are mounted on a portable frame structure. Lime and water are mixed in the primary tank to form a lime slurry. The lime slurry is then introduced into the auxiliary tank. A product stream of lime slurry is drawn from the primary tank until it is depleted. Lime slurry is then drawn from the auxiliary tank to supply a continuous stream of lime slurry to the job site while the primary tank is being refilled with lime and water to form a second lime slurry. The second lime slurry is then introduced into the auxiliary tank so that it is filled again and a second product stream of lime slurry is drawn from the primary tank. The process is repeated until a desired amount of lime slurry is supplied to the job site. In an alternate embodiment, the product stream is drawn continuously from the auxiliary tank while the auxiliary tank is being replenished from the primary tank.
    • 将石灰浆料的连续产品流提供给位于远离永久性石灰生产设备的作业现场的方法和设备利用安装在便携式框架结构上的主要和辅助罐。 石灰和水在初级罐中混合形成石灰浆。 然后将石灰浆引入辅助罐中。 石灰浆料的产品流从初级罐中抽出,直到其被耗尽。 然后将石灰浆从辅助槽中抽出,以将酸性浆料连续供给到作业现场,同时将主油罐用石灰和水重新填充以形成第二石灰浆。 然后将第二石灰浆引入辅助罐中,使其再次填充,并且从主槽抽取第二产物流的石灰浆料。 重复该过程,直到将所需量的石灰浆料供应到作业现场。 在替代实施例中,在辅助箱从主油箱补充的同时,从辅助罐连续地抽取产品流。
