A method of forming a structure includes a) excavating a material; b) homogenizing the material; c) ensuring aluminosilicate levels in the material; d) increasing alkaline levels of the material; e) foaming the material; and f) injecting the material onto a surface, wherein the material forms into a foam-like structure when injected.

A supplementary cementitious material used in combination with an activator such as Portland cement to produce a hydraulic binder. The supplementary cementitious material is based on physico-chemically treated filter cake product extracted from dredged sediments and can partially replace Portland cement clinker in conventional concrete applications with positive effects on sustainability (reduction of CO2 emissions, upcycling of residues).

The present invention includes a method for determining a soil classification comprising: obtaining a soil sample; conducting two or more of the following tests in the field, wherein the tests are selected from wash test, a feel test, a test tube particle graduation, or a jar test, to obtain raw data for each test; and calculating the soil classification from the raw data obtained in the field by applying a previously obtained validation dataset obtained from a training and validation soil classification calculation using known samples. The invention also includes compressed earth blocks made using the present invention.

A method of producing artificial bio-soil aggregates based on foamed concrete for plant growth that can ensure sufficient moisture and plant nutrients for the habitat of plants in non-soil conditions; obtain a lightweight, durable, and deep soil layer, and continuously provide a favorable environment for plant growth. A paste is prepared by mixing cement with an admixture, such as ochre and burnt-furnace slag; foamed concrete is formed by adding foam bubbles with an appropriate foaming rate to said paste, thereby producing soil concrete. When the foamed concrete is used, a designated compressive strength can be ensured and a number of pore spaces are formed, which allow the air to be sucked and expelled therethrough and store moisture therein. Also, hydrogel that is incorporated into the foamed concrete may supply nutrients required for plant growth, improve pest resistance, and store and supply a large amount of water.

A method to manufacture a native soil flowable fill includes hydro excavating native soil to form a hole at a first excavation, transferring the native soil from the first excavation to a debris tank, and adding a pozzolan component, cement and water to the debris tank. The method also includes mixing the native soil in the debris tank using a mixing apparatus to form the native soil flowable fill, and transferring the native soil flowable fill back to the first excavation into the hole. The native soil flowable fill comprises 30-90% by weight of native soil, 0-50% by weight of the added pozzolan component, 0-50% by weight of the cement, and 10-45% by weight of the water.
