Abstract.The effects of the cross-sectional area of the reinforcement, the cross-sectional size of the specimen and the strength of ultra high performance concrete with coarse aggregate (UHPC-CA) on the flexural capacity of UHPC-CA beams with HRB500 grade high-strength reinforcement are analyzed by orthogonal test. The results show that the influence of various factors on the flexural capacity of high-strength reinforced UHPC-CA beams is in the order of specimen section size > reinforcement section area > UHPC-CA strength. With the increase of the three factors, the bending bearing capacity is improved … Read more →

Abstract.Mining destroys the environment and occupies arable land, causing serious social problems. In recent decades, land reclamation and ecological restoration of mine wasteland have become a hot topic of interdisciplinary research. However, compared with developed countries in Europe and America, China's mine wasteland work has the characteristics of low land reclamation rate and poor reclamation quality. This paper discusses the soil reconstruction technology, physical and chemical improvement technology and vegetation restoration technology of land reclamation. At the same time, it is believed … Read more →

Abstract.In this study, butyl methacrylate (BMA), methyl acrylate (MA), cetyl methacrylate (HMA) as monomers, cetyl trimethyl ammonium bromide (CTAB) as dispersant, benzoyl peroxide (BPO) as initiator,N, n-methylene diacrylamide (MBA) as crosslinking agent, A kind of ternary oil absorbing resin was prepared by suspension polymerization. The range of long chain monomer (HMA), initiator (BPO), crosslinking agent (MBA) and surfactant (CTAB) was optimized by single factor experiment, and the best resin Poly (HMA-co-BMA-Co-MA) was obtained by orthogonal experiment design. The structure was analyzed by … Read more →
