Research on Interfacial Bonding Property of Modified Fiber Reinforced Concrete and Present Situation Analysis by ZHANG Xiaoli, YUAN Yuan

“…So far,scholars at home and abroad have done a lot of research to improve the bonding strength between the fiber and the matrix in concrete and ultimately to enhance the fiber reinforcement effect.This paper summarizes tests at home and abroad on the interfacial bonding property of fiber reinforced concrete and their evaluation indexes and analyzes the mechanism and the influence of the interfacial bonding property of modified fiber reinforced concrete from the two aspects of matrix property and fiber surface characteristics.It is concluded that nanomaterials,organic polymers,and part of the active minerals all affect the hydration process of cement concrete. The hydration evolution process,microstructure,and modification mechanism of the matrix in concrete under multi-mineral and polymer hybrid modification need to be studied immediately.Optimal modification methods for different fibers should be proposed according to economical efficiency,construction technology,and modification effect.…”

Mechanism of steel slag powder stabilization and improvement of expansive clay by Yinlei SUN, Chuan YU, Lei LIAO, Zhifei LI

“…By reducing the particle size of SSP, adding alkaline exciters or compound modification can improve its cementation activity and hydration rate. (3) SSP as a soil conditioner can significantly improve the performance of expansive clay, including expansion and contraction and mechanical properties. (4) The studies on the interaction mechanism between SSP and clay and the application effect of composite exciters remain insufficient and requires further investigation. (5) Future research should consider the chemical and physical properties under the coupling of different factors, including the chemical-mineral composition and the microstructure evolution law of the soil, as well as the mechanical properties of the soil under the water-chemical-force interactions. …”
