The invention relates to mortar or concrete produced with a hydraulic binder, comprising aggregates from cinders from the bottom of municipal waste incinerators and/or from slurry from wastewater treatment plants, or other natural or artificial aggregates, of different particle sizes depending of the use thereof as mortar or concrete, and a binder consisting of: glass and/or other pozzolans; pure Portland clinker with gypsum or plaster of Paris, or the resulting cements following the grinding thereof; and/or optionally lime, depending on the quantity of glass and/or pozzolans; all of the materials forming the base of the binder being ground and mixed together until a binder is obtained, together with the aggregates, with cementing mineral neoformations and a strong pozzolanic character.

This geopolymer molding production method comprises: a mixing step (S1) for mixing a first material containing aluminum and silicon with a hydrate of an alkali stimulant containing a hydrate of an alkaline hydroxide and/or a hydrate of an alkaline silicate; a compaction step (S2) for compacting the mixture obtained in the mixing step (S1) into a compacted mixture; and a curing step (S3) for curing the compacted mixture.

The present invention relates to additives and, more specifically, the use of biochar, in concrete and other cementitious materials to provide for building materials that have a lower carbon footprint than their traditional counterparts. Traditional methods for production of cement produce large amount of carbon dioxide (CO2). When coupled with the massive demand for cement building materials around the world, this means that the cement production has a significant impact on the amount of CO2 produced globally. By including biochar and other additives along with, or instead of some traditional components of cement, one may be able to provide for cementitious building materials that sequester carbon, rather than release it.

[Object] To provide a building material having excellent durability. [Solution] A building material has a convex part formed on a surface thereof, the convex part including a first lateral surface part and a second lateral surface part corresponding to the first lateral surface part. The building material is formed from a mixture containing a hydraulic material, an admixture, and a plant-based reinforcing material, and the plant-based reinforcing material at least in the convex part is distributed in the mixture with the hydraulic material and the admixture attached to the plant-based reinforcing material. A distribution of the plant-based reinforcing material in the first lateral surface part and a distribution of the plant-based reinforcing material in the second lateral surface part are substantially the same. Desirably, the convex part includes a first edge part that is an edge part of the first lateral surface part and a second edge part that is an edge part of the second lateral surface part and that corresponds to the first edge part, and a distribution of holes formed in the first edge part and a distribution of holes formed in the second edge part are substantially the same.

Products, including treatment compositions, and methods for improving cement performance are provided. More specifically, products and methods for improving cement hydration, and thus cement performance, using vegetation are provided. The vegetation may be processed into a vegetative extract that may be used to create a treatment composition. The treatment composition may be used to enhance hydration of cement. The products and methods disclosed herein may be used to create a stronger, lower cost, and longer-lasting cementitious product.

A vegetal concrete masonry unit is provided which comprises cooked crop residues, binder and pulverized fuel ash in a mass ratio of 1:1:1.5 to 1:1.5:3.
