A cement composition and a process are provided for recycling a waste material by using the waste in the manufacture of Portland cement. The process generally comprises mixing a first quantity of the waste material thoroughly with a second quantity of a solid material so as to produce a non-compacted additive. The non-compacted additive is applied to cement clinker, wherein the additive is utilized as a substitute for virgin ingredients normally used in the manufacture of the Portland cement. In an embodiment, the non-compacted additive comprises a consistency of wet earth which is readily pliable with the second quantity by weight not exceeding three times the first quantity by weight. The cement clinker is then pulverized so as to distribute the additive within the resulting Portland cement.

Base grains intended to be assembled together to form granules for a composition of construction materials useful in the field of building, public works and civil engineering, characterised in that each base grain consists of a core formed by an agglomerate of fragments of compressed waste and associated with each other by a micro-concrete with a carbonated hydraulic binder which has undergone hydraulic setting, the core being enclosed in a shell formed by a reactive powder micro-concrete (RPMC) which has undergone hydraulic setting.

Compositions, tools and methods for the manufacture of construction materials, masonry, solid structures and compositions to facilitate dust control are described. Compositions and methods for the manufacture of pigmented solids structures for which can be used for construction and/or decoration are also described. 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. 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. Compositions containing microorganisms and pigment as kits that can be added to most any aggregate materials are also described.
