The summary of the utility model describes a light mineral organic insulation product that is characterized by the modification of elements found in nature and the environment which, through the process described above, lead us to obtain this insulation which Due to its characteristics and composition of the elements described and its great advantages in the use of resources that are polluting to the environment, it will generate a great impact in the construction industry because, among other advantages, costs are considerably reduced, as well as the times of installation which will optimize human resources saving man-hours because its installation is extremely simple and the materials are light and manageable.

This isolation aims to strongly promote a new generation of less aggressive proposals for the planet that will have repercussions for the benefit of future generations.

The embodiments herein are directed to dry wall waste mixtures, formed under pressure into example embodiments referred to herein as dry wall waste blocks (DWBs) and/or gypsum wallboard waste blocks (GWWBs) and tile structures. DWBs/GWWBs mixtures in particular, often incorporate a higher percentage in the composite mixtures from about 60% up to 85% of dry wall waste than other mixtures and beneficially often incorporates substantially all of the wallboard facing paper as part of the composite mixture. That is, waste processing is simplified by comingling core and paper layers in the final product. DWBs/GWWBs mixtures utilize demolition and construction waste, replacing a high percentage of Portland cement with waste-derived binder.

A cement composition is disclosed containing: cement; cellulose nanofibers; and water, wherein a mass ratio of the water to cement is 0.4 or less. The cement is preferably Portland cement. It is preferred that the Portland cement is high-early-strength Portland cement, and that a mass ratio of fine aggregate to the high-early-strength Portland cement is 2.0 or less. A unit amount of cellulose nanofibers in the cement composition can be 0.1 kg/m.sup.3 to 15 kg/m.sup.3 Furthermore, a hardened body of the cement composition is disclosed, wherein a ratio of a splitting tensile strength of the hardened body at a material age of 91 days obtained by curing in air, to the splitting tensile strength of the hardened body at the material age if 91 days obtained by curing in water is 0.90 or more and 1.10 or less, the splitting tensile strength being measured in accordance with JIS-A-1113 (2006).

The invention is directed to compositions and methods for the manufacture of pigmented solids structures for which can be used for construction and/or decoration. Manufacturing comprises fixing one or more pigments to an aggregate material such as crushed rock, stone or sand. The pigmented aggregate is incubated with urease or urease producing microorganisms, an amount of a nitrogen source such as urea, and an amount of calcium source such as calcium chloride forming calcite bridges between particles of aggregate. The resulting solid has a hardness and colorfastness for most any construction material. Using selected aggregate and pigment, the process also provides for the manufacture of simulated-stone materials such as clay or granite bricks or blocks, marble counter-tops, and more. The invention is also directed to composition containing microorganisms and pigment as kits that can be added to most any aggregate materials.
