The invention relates to a method for producing a solid construction material which is preferably substantially free of hydraulic binder, comprising the steps of: a. extracting a mineral fraction comprising argillaceous particles of a soil; b. optionally adjusting the particle size of the mineral fraction extracted, in particular in relation to its clay, sand, gravel or loam content, if necessary; c. preparing a first aqueous grout from at least one part of the mineral fraction extracted and optionally adjusted in terms of particle size; d. adding a dispersant that can disperse the argillaceous particles in the first grout in order to obtain a second aqueous grout, e. adding a coagulant that can promote the agglomeration of the argillaceous particles in the second grout in order to obtain an aqueous construction material grout; f introducing the construction material grout into a formwork; and g. allowing the evaporation of the water contained in the material grout in order to obtain a solid construction material.

Implementations described and claimed herein provide a process for creating a low-buoyancy cellular concrete that may include cement, water, and various surfactants including hydrophilic additives to produce the low-buoyancy cellular concrete. The low-buoyancy cellular concrete wet mix maintains its cellular properties while it is placed and cures. After curing, water may be absorbed into the low buoyancy cellular concrete via a combination of physical and chemical characteristics. An open cell structure of capillaries facilitates wicking action of water into the low buoyancy cellular concrete via capillary channeling (through the cementitious matrix between the micro-bubbles, and in some cases into the micro-bubbles as well). Further, the hydrophilic additive in the foam surfactant facilitates absorption of water into the low buoyancy cellular concrete through diminished surface tension at an interface of the cellular concrete and a body of water and at and between the microbubbles.

The present invention discloses cement mortar containing excavated soil prepared by replacing natural sand with engineering soil, and a preparation method therefor and an application thereof. The preparation method includes drying and grinding waste engineering soil taken from a construction site first, sieving and mixing it to form recycled engineering soil, and putting the recycled engineering soil and natural sand into a mortar mixer according to a certain proportion to form a sandy soil mixture; then pouring water and cement into the mortar mixer, adding a part of the sandy soil mixture and a part of a water-reducing admixture, and evenly stirring; and finally, adding the remaining sandy soil mixture and water-reducing admixture, and evenly stirring to obtain the cement mortar containing excavated soil.
