Ultrahigh-toughness concrete and a preparing method thereof

Abstract

Ultrahigh-toughness concrete and a preparing method thereof are disclosed. The concrete is prepared from, by weight, 380-580 parts of cement, 150-170 parts of slag powder, 250-380 parts of fly ash, 200-400 parts of quartz sand, 13-15 parts of bamboo wood phenolic alcohol liquified resin, 13-18 parts of polypropylene resin, 0.5-1.5 parts of carboxymethylcellulose, 23-47 parts of core-shell acrylic acid elastic emulsion, 5-10 parts of a chemical-resistant modifier, 14-18 parts of bamboo fibers, 2.5-8.5 parts of nanometer silicon particles, 7-13 parts of nanometer calcium carbonate, 3-5 parts of anionic polyacrylamide, 3.7-8.3 parts of poly(diallyldimethylammonium chloride), 0.4-1 part of poly(ethylene glycol) acrylate, 20-30 parts of an acrylic emulsion, and the like. The ultrahigh-toughness concrete has high tensile strength, high compressive strength, ultrahigh ductility, good energy consumption capacity and good elastic modulus.

AI Technical Summary

Benefits of technology

In this patented technology, we use different types of monomers or oligonucleotides called initiators that create networks made up of specific molecules attached together through ionizable interactions between them. These networks help increase flow properties for liquids like hydraulic bindings without causing cracks over longer periods of times compared to traditional methods such as adding plaster before casting it. Additionally, these networks also contain silicon oxane (SiO2) nanoparticles added onto their surfaces, providing protection against corrosion caused by various substances present within the liquid being casted. Overall, these technologies enhance the quality control of poured concretes and provide improved structural integrity under harsh environments.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the quality control over concretes used in construction projects during their production process. Specifically, it addresses issues related to cracks caused due to environmental factors such as temperature changes, moisture content differences between batches, pressure applied when filling them into forms (concrete), and impact on the structure's integrity after curing.
