High-Performance Concrete Nanomodified with Recycled Rice Straw Biochar

The development of new and improvement existing technologies based on the use waste products from various industries or recyclable materials is a current trend in construction industry. Including composition binders concrete by-products industry, reducing proportion Portland cement, it crucial to maintain improve resulting products’ mechanical characteristics life cycle. main aim study was investigate influence biochar additive microstructure properties obtain with improved due nanomodification rice straw recycled biochar. An environmentally friendly technology for manufacture obtained, using agricultural waste, straw, as its components, developing nanomodified processed biochar, identifying dependences their coal. It has been established that most effective dosage addition amount 6% by weight cement. expressed increase physical changes deformability according results analysis stress-strain diagrams. strength ranged 17% 25%. modulus elasticity increased 14%. deformation decreased 12% 24%. Introducing finely dispersed modified electromagnetic method leads decrease cement consumption up 10%.
