A green concrete composition comprising: a binder component comprising Portland cement (C), volcanic ash (VA), metakaolin (MK), and colloidal nano-silica (CNS); an aggregate component comprising fine aggregates (FA) and coarse aggregates (CA); water (W); and a super plasticizer.

A method of producing green concrete, and particularly to green concrete with Portland cement (C), natural basaltic volcanic ash pozzolan (VA), and microsilica (MS). The green concrete described herein is a high-performance green concrete composition that partially substitutes Portland Cement (C) and can further include fine aggregates (FA) and coarse aggregates (CA), water (W), and a super plasticizer (SP). The green concrete described herein can be cured at ambient temperature and can have a better compressive strength and durability properties, and high shrinkage resistance as compared to conventional concrete and, as such, can be used for high performance applications.

A manufacturing process of a concrete product includes: (1) extracting calcium from solids as portlandite; (2) forming a cementitious slurry including the portlandite; (3) shaping the cementitious slurry into a structural component; and (4) exposing the structural component to carbon dioxide sourced from a flue gas stream, thereby forming the concrete product.

GEOPOLYMER CEMENT MADE FROM RECYCLED GLASS AND ITS MANUFACTURING PROCESS, the present invention relates to a geopolymer cement from recycled glass and its manufacturing process that, according to its characteristics, can produce geopolymer cement in its own and specific binding structure of a rigid solid type, made from recycled glass (waste), alkalis and water, and obtained directly by milling, homogenization, alkalinization and curing at room temperature, or forced curing of its components, and it can be used, in an extremely convenient, safe and cost-effective manner, as a new geopolymer matrix to replace the traditional ones made from metakaolin, blast furnace slag, fly ash or volcanic rock in various applicationsto manufacture cement slabs, concrete, fiber composites and materials for coatings, aligned with an eco-friendly concept for complete reuse of this waste which is disposed in the environment.

An environmentally-friendly quartz composite board and a manufacturing method therefor are provided. A raw material of the environmentally-friendly quartz composite board includes a quartz particle, a building material waste particle, a resin, a coupling agent and a curing agent. After the raw materials are stirred, mixed, pressed and cured, the required environmentally-friendly quartz composite board is obtained. The invention allows construction material waste that is originally difficult to use to be effectively recycled and reused, and provides an innovative and environmentally-friendly sustainable product, thereby meeting consumers' expectations for the industry on ESG issues.

The present application belongs to the technical field of civil and architectural engineering materials, and in particular relates to an environmental and low-carbon foamed lightweight soil prepared by using CO.sub.2 and MgO as raw materials. Raw material compositions of the carbon sequestration foamed lightweight soil include, in parts by weight, 10 to 200 parts of MgO, 10 to 100 parts of a filler, 2 to 45 parts of a CO.sub.2 bubble cluster and 20 to 400 parts of water. The present application is made in view of the problems of large carbon emission and serious energy consumption caused by a cement solidification agent used in traditional foamed lightweight soil.

The one or more cement precursors comprises one or more of calcareous sludge; paper pulp, biomass flyash; bag house dust; biomass sludge; filter cakes from bio industry's and wastewater treatment; bio ash; biomedical ash; agricultural ash; sugar cane bagasse; rice husk ash; palm oil fuel ash; oxygen furnace slags; plant stalks; bio char; starch; pyrophyllite; or a combination thereof. The one or more alkaline activating agents comprises potassium silicate, potassium hydroxide, sodium hydroxide, sodium silicate, calcium hydroxide, magnesium hydroxide, reactive magnesium oxide, calcium chloride, sodium carbonate, silicone dioxide, sodium aluminate, calcium sulfate, sodium sulfate, or dolomite, or a combination thereof. The system comprises a vertical impact mixer.

Methods and systems for storing and mineralizing carbon dioxide in soil are disclosed herein. In some embodiments, the method comprises adding lime and carbon dioxide to a soil column including soil to form treated soil. After adding the lime and carbon dioxide, the method also includes strengthening the treated soil in the soil column by mineralizing the lime and carbon dioxide in the soil column. The method can further include adding a binder to the soil column and mixing the binder with the soil, lime, and carbon dioxide. The binder can include, for example, pozzolan, cement, cementitious material, and/or a manufactured calcium carbonate product.

An environmentally friendly composition of matter comprising a limestone and fiberglass based waste material used to substitute out a portion of natural aggregate with said waste material so as to preserve natural resources, protect the environment and prevent depletion of landfill capacity and reuse unusable waste products into environmentally useful products.
