A particulate sound absorption board and its preparation method. The said particulate sound absorption board consists of binding agent and sound absorption particle; the external surface of sound absorption particle is covered with a layer of binding agent, and the angularity coefficient of particle covered with binding agent is less than 1.3; the said sound absorption particle consists of skeleton particle and filling particle, in which the former is used for sound absorption board skeleton, and the latter flows into the pore between skeleton particles to form sound absorption pore, and the average diameter of cross section of sound absorption pore is 0.07 mm. The two-stage manufacturing technology (i.e. coating, curing and then shaping) is adopted for the said preparation method to prevent the pore between particles from being blocked by excess binding agent, and further improve the angularity coefficient of particle.

A hybrid additive for use in construction materials such as asphalt and concrete is disclosed. The additive includes pellets formed of a plastic or polymer material, and one or more of fibers, pozzolans, nano-carbon tubes, glass, recycled asphalt shingles (RAS), liquid anti-strip, hydrated lime, rejuvenators, cementitious material, and ground tire rubber. Also disclosed are hybrid composite materials useful as paving and building materials, and methods of making the same. The hybrid additives were found to maintain the positive performance aspects of typical asphalt and concrete mixtures, while improving the performance of the mixtures by increasing bonding and strength within the mixtureand therefore increasing useable life and lowering costs.

Provided herein are active flow-through carbonation curing systems useful for contacting carbon dioxide (CO.sub.2) gas streams with concrete materials under ambient pressure. This contacting causes a carbonation reaction in which CO.sub.2 forms materials, such as, but not limited to, calcium carbonate (CaCO.sub.3). The methods include, but are not limited to, contacting a conditioned flue gas containing CO.sub.2 inside of a carbonation chamber with green bodies or concrete components in which flue gas properties such as temperature, relative humidity, flow rate, and flow direction, are self-adjusted during the curing process based on a self-sensing instrumentation system inside a curing chamber and carbonation kinetic regression model. This system improves CO.sub.2 capture efficiency and material performance while reducing processing energy.

The disclosure is directed to kits, compositions, tools and methods comprising a cyclic industrial process to form biocement. In particular, the disclosure is directed to materials and methods for decomposing calcium carbonate into calcium oxide and carbon dioxide at an elevated temperature, reacting calcium oxide with ammonium chloride to form calcium chloride, water, and ammonia gas; and reacting ammonia gas and carbon dioxide at high pressure to form urea and water, which are then utilized to form biocement. This cyclic process can be achieved by combining industrial processes with the resulting product as biocement. The process may involve retention of calcium carbonate currently utilized in the manufacture of Portland Cement.
