摘要:
A process for sealing soil formations, wherein a mineral sealing layer of a cohesive soil with the addition of powdery silicate of sodium is applied and mechanically compacted, and wherein: (a) firstly a homogenous mixture is prepared from a cohesive soil having a water in the wet area of the Proctor curve, with the addition of a powdery, aluminate-free soft gel-forming agent; (b) when the soft gel-forming agent has dissolved in the groundwater, powdery silicate of sodium is incorporated in homogeneously; and (c) finally the mixture is mechanically compacted.
摘要:
The invention relates to a method of rendering a soil or another material like a mortar, a binder, or a concrete impervious by injecting it with a silica solution. A finely ground powdered compound containing calcium with a solubility in water of between approximately 0.01 g/l and approximately 2 g/l is mixed into the silica solution, which has a ratio of SiO.sub.2 to Na.sub.2 O of between 1 and 1.3, before injection.
摘要:
Soil is intimately contacted with water containing a catalytically effective amount of a novel catalyst to improve the fertility thereof. In a preferred variant, the water which is intimately contacted with the soil may also contain catalyst treated lignite. Plants grown in the treated soil are more vigorous and resistant to disease or adverse environmental conditions. The yields are higher in instances where the plants are grown commercially for food or fiber, and the plants have a more pleasing appearance in instances where they are grown for decorative purposes. The catalyst is prepared by a process including the steps of admixing a water soluble alkali metal silicate with an aqueous medium containing carefully controlled amounts of water soluble substances which are sources of calcium ion and magnesium ion, reacting the same to produce an aqueous colloidal suspension of the reaction product, admixing a micelle forming surfactant with the aqueous medium, and agitating the aqueous medium containing the colloidal particles and surfactant to form catalyst containing micelles. The catalyst treated lignite is prepared by a process including intimately contacting lignite with an aqueous medium containing the novel catalyst until it is soluble. Presently preferred processes for preparing the novel catalyst and the water soluble catalyst treated lignite are described.
