Construction product
A construction product and a method of manufacturing the construction product is provided. The method comprises: producing a mixture of bio-aggregate and a binder, the binder comprising an alkali earth metal oxide or alkali earth metal hydroxide; and exposing the mixture to a carbon dioxide containing feed stream for accelerated carbonation of the mixture. The construction product comprises an accelerated carbonation-cured mixture of the binder and the bio-aggregate. The binder may be alkali earth metal oxides; alkali earth metal hydroxides; cement (Ordinary Portland Cement, White Cement, calcium aluminate cement, natural cement); lime; pozzolanic elements such as metakaolin, silica fume, fly ash. The bio-aggregate may be selected from one or more of: maize; wheat; rice; barley; millet; grasses; rice husk; straw; squash; pumpkin; watermelon; cucumber; melon; hops; cannabis; celtis tress; nettles; wildflowers; rape straw; algae; seaweed; bamboo; rapeseed; barley; oats; flax; rice straw; corn straw; giant miscanthus; sugarcane bagasse; sisal straw; hemp. Preferably, the bio-aggregate consists of one or more moderate silica content-containing plants, and/or one or more high silica content-containing plants.
