This study investigated the effect of interaction between ultrafine slag powder (USL) and limestone (LS) on rheology behavior, microstructure, fractal features UHPC. The results indicated that B2 with mass ratio 2:1 USL LS obtained highest compressive strength lowest yield stress. combination facilitated cement hydration, ettringite, monocarboaluminate (Mc) formation, as well increase in polymerization C-S-H. synergistic action refined pore structure due to formation Mc, compensating for...
In order to study the feasibility and superiority of foam lightweight concrete (FLC) for existing buried high-pressure gas pipeline section under soft soil roadbed, this paper takes second phase Foqingcong Expressway project as engineering background, designs two roadbed treatment schemes, pile composite foundation method, (FLC). Through bearing capacity settlement calculations, it was confirmed that FLC is feasible roadbeds in pipe section, three major aspects analysis, namely safety...
Dynamic safety factors during the construction of an overlapping tunnel-group metro station were studied in framework strength-reduction finite element method. Based on equivalent plastic strain and displacement surrounding rock, its damage mode under typical excavation conditions was investigated. The aim this investigation to provide information for design activities concerning supporting system pre-reinforcement ground. accuracy model assessed by comparing ground settlements obtained from...
The aim of this paper is to understand the relationship between patterns adverse childhood experiences(ACEs), screen time and non-suicidal self-injury behaviors(NSSI) among middle school students.Stratified cluster sampling method was used select 14 500 students(7347 boys 7153 girls; 7247 junior high students 7253 senior students; 7619 urban 6881 rural students) from Shenzhen, Guiyang, Nanchang Zhengzhou Cities. Questionnaire surveys were conducted using child abuse questionnaire, household...
