Lighweight concrete composition for soil stabilization, especially in shoreline and waterbottom areas

摘要

A lightweight concrete composition is mixed from cement, sand, water, and organic material, and placed on an area of soil, proximal a body of water, to protect the soil from erosion and the like due to water action. Preferably, the organic material comes from the area in which the soil is being stabilized, and may include soil, leafy matter, and ground up wood, forming a particulate organic material. Preferably, the final density of the resulting lightweight concrete composition is greater than the density of the water in the body of water, and less than the density of the soil being stabilized. A representative density range is between 62.43 pounds per cubic foot and 100.00 pounds per cubic foot.

主权项

1. A method of stabilizing an area of soil, at least a part of said area of soil underlying a body of water, said soil and the area proximal thereto defining a soil stabilization area, said soil stabilization area comprising organic feedstock therein, comprising the steps of:
providing a barge positioned in said body of water proximal said area of soil to be stabilized, said barge comprising a mixer and a pump thereon; providing a means for creating particulate organic material from organic feedstock; transferring organic feedstock gathered from said soil stabilization area to said means for creating particulate organic material, and producing a volume of particulate organic material therefrom; with said mixer, mixing cement, sand, water from said body of water, and a quantity of said particulate organic material in proportions suitable for producing a lightweight concrete composition having a density greater than the density of said water in said body of water, and less than the density of said soil; with said pump, pumping said lightweight concrete composition onto said soil to form a layer of lightweight concrete composition thereon; allowing said lightweight concrete composition to cure, thereby forming a layer on said soil resistant to deterioration thereof by water action.
