Abstract: This disclosure provides an eco-friendly multi-layer fabric reinforced cementitious matrix (FRCM) enhanced by nanoparticles. The FRCM is developed for structural strengthening and/or repairing in reinforced concrete buildings. The FRCM consists of multi-layer fabrics as load-carrying and crack control components and a cementitious matrix as bedding for the fabric layers. The cementitious matrix is eco-friendly based on a main constituent of ground granulated blast-furnace slag (GGBS) and recycled glass cullets. Some additions, including nanoparticles, superplasticizer, hydroxy propyl methyl cellulose and/or starch ether, are added to achieve proper workability and rheology for application requirements, and to enhance fresh properties, mechanical properties and/or durability. Man-made fabric and natural fabric are embedded in the cementitious matrix with designated purposes of load carrying and crack control.

Abstract: A polymerizable quaternary ammonium compound (QAC) including an acrylate group and a cationic group is provided. Specifically, the acrylate group is capable of polymerization so as to integrate the QAC into a macromolecular chain of a polymer through an addition polymerization for introducing antimicrobial and antiviral activities. For instance, the polymerizable QAC can be polymerized with a vinyl group monomer, an acrylate monomer, a silane monomer, an adhesion monomer and an emulsification monomer to form a synthesized polymer emulsion. The polymer emulsion can be further incorporated into a coating material to provide a transparent, water resistant, antimicrobial and antiviral waterborne coating on a substrate's surface.

Abstract: A reclamation fill stabilizing composition for accelerated soil stabilization of high water-content waste soils/marine mud. The fill stabilizing composition includes a hydrolysis polymerization agent for chemically reacting with water in waste soil/marine mud. A gelling geopolymerization agent chemically and physically locks the water in its formed 3-D aluminosilicate microstructure. A sol-gel immobilization agent chemically and physically traps the water by reacting and bonding with the water. A nano-modification agent provides additional crystal nuclei to increase the effects of hydrolysis polymerization, gelling geopolymerization, and sol-gel immobilization. The reclamation fill stabilizing composition is mixed with high water-content waste soil such as marine mud. The marine mud is rapidly transformed into a compactable fill material within a stabilization curing period as short as 3 hours. Following stabilization, the treated marine mud is compacted (e.g., with a vibratory roller) into a layer of about 240 \~300mm with adequate stiffness (CBR value of at least 15%).

Abstract: Efflorescence resistance of concrete blocks is enhanced through the use of glass powder in the concrete composition. The glass powder permits a reduction in the cement content; the glass powder also creates a pozzolanic reaction to change the free calcium ions in calcium hydroxide to calcium silicate to fix the calcium ions inside concrete. The composition includes cementitious binding material of ordinary Portland cement, fly ash, calcium sulfoaluminate cement, ground-granulated blast-furnace slag in an amount from 20 to 25 wt. %. Coarse aggregate is provided from 10 to 15 wt. percent. Fine aggregate is from 32 to 39 wt. %. The composition further includes glass powder having a diameter of less than approximately 75 microns in an amount from 17 to 23 wt. %. Water is present in an amount from 6 to 9 wt. %. The dry density of formed paving blocks is 1800-2200 kg/m3.

Formed on the core materials is at least one layer of shell material which includes one or more of GGBS, fly ash, recycled concrete powder, recycled glass powder, or biochar powder. The high-strength, lightweight core- shell aggregates have a loose bulk density less than approximately 980 kg/m3, a crushing strength higher than approximately 4 MPa, a water absorption of less than 20%, and a carbon emission of approximately 181 kgCO2eq/t or less. Lightweight concrete is formed by incorporating the high-strength, lightweight core-shell aggregates with cement to create concrete with a density of 1900 kg/m3 or less.
