    摘 要:以?;郀t高鈦礦渣粉為主要原料,水玻璃為激發劑,鋁粉為引氣劑,制備了堿激發高鈦礦渣免燒陶粒。試驗發現單一使用高鈦礦渣粉制備的陶粒保氣量不足、堆積密度較大,提出添加少量粉煤灰或固硫灰對其進行了改性,研究改性前后陶粒性能,利用XRD、SEM等手段探討了陶粒礦物組成和微觀結構。試驗結果表明,摻入適量的粉煤灰或固硫灰,體系漿體黏度提高,保氣量改善,能制備出容重更小的免燒陶粒。 Abstract: Sinter-free lightweight aggregates(SLWA) have been prepared by using titanium slag as raw material, sodium silicate water glass as alkaline activator and aluminite powder (AP) as air-entraining agent. And the relatively high bulk density of SLWA was observed, due to the low viscosity and gas preservation of pastes when titanium slag was used alone. Therefore, fly ash and circulating fluidized bed combustion fly ash (CFBC) were used to improve properties of SLWA.And the XRD and SEM tests were used to study the mineral composition and microstructures of prepared SLWA. The results showed that the viscosity and gas preservation could be improved. And the SLWA with lower bulk density has been obtained.

    摘 要:針對目前隧道滲漏水的現狀和原因,擯棄以室內試件抗滲等級評價襯砌混凝土防滲性能的傳統思路,以改善混凝土流動性及抗裂性進而提升實體結構防滲性能的新思路來進行襯砌混凝土的配制。在此基礎上,通過流動性控制、外加劑改性、內養護減縮等途徑開展了襯砌混凝土性能優化研究,制備出了不依賴于現場施工水平的大流動性內養護抗裂襯砌混凝土,并結合施工縫及變形縫等細部防水措施,在某富水區地鐵隧道進行了工程應用,取得了較好的防滲漏效果。 Abstract: According to the current status and cause analysis of tunnel seepage, a new idea to improve the fluidity and crack resistance of concrete and thus enhance impervious performance of concrete structure was proposed, replacing the traditional idea of using laboratory permeability grade of the specimens to evaluate impervious performance of lining concrete. On this basis, with the technologies of fluidity control, admixtures modification and shrinkage reducing by internal curing, study on performance optimization of lining concrete was carried out, and lining concrete with performance of high-fluidity, internal curing and high anti-cracking was prepared, which was independent of construction level in-site. Combined with the detail waterproof measures of construction joint and deformation joint, above measures were applied in a metro tunnel served in rich water zone, and desirable effect of seepage prevention was obtained in this project.

    摘 要:水泥混凝土路面加鋪瀝青混合料形成復合式路面,其層間的界面特性是復合式路面耐久性的重要影響因素,而水泥混凝土路面表面的細觀粗糙度和宏觀紋理是影響復合式路面界面黏結性能的重要因素。本文針對不同尺度下水泥混凝土路面構造特性進行了研究,結果表明,機制砂混凝土路面表面粗糙度及抗滑性能指標普遍低于河砂混凝土;不同處理方式作用下,水泥混凝土路面表面細觀粗糙度和宏觀構造深度差別很大。 Abstract:The interfacial characteristics of the composite pavement is an important factor affecting the durability of composite pavement made of asphalt mixture on cement concrete pavement. And the microcosmic roughness and macroscopic tectonic depth of the cement concrete pavement surface are the important factors which affect the adhesive performance of the composite pavement interface. The structural characteristics of cement concrete pavement under different scales are studied. The results show that the surface roughness and anti-sliding performance of the machine-made sand concrete pavement are generally lower than those of the river sand concrete. Under the different treatment methods, the surface roughness and macroscopic structure depth of cement concrete pavement are very different.

    摘 要:以成都地區裝配式公共建筑為例,分別選取64mm厚模塑聚苯乙烯泡沫塑料保溫板(簡稱EPS保溫板)、52mm厚擠塑聚苯乙烯泡沫塑料保溫板(簡稱XPS保溫板)、39mm厚聚氨酯硬泡沫塑料保溫板(簡稱PUR保溫板)、58mm厚硬質酚醛泡沫保溫板(簡稱PF保溫板)作為夾心保溫層材料,研究預制混凝土夾心保溫外墻板的內部冷凝情況,其中保溫材料的厚度依據GB 50189—2015《公共建筑節能設計標準》對外墻傳熱系數的最低要求選定。結果表明,各類型預制混凝土夾心保溫墻板內部均會出現冷凝現象,但冷凝區域較小,重量濕度增量依次為1.08%、0.75%、4.50%和1.36%,滿足GB 50176—1993《民用建筑熱工設計規范》的要求。 Abstract: Taking the assembled public buildings in Chengdu as an example, EPS insulation board with 64mm thick, XPS thermal insulation board with 52mm thick, PUR thermal insulation with 39mm thick and PF thermal insulation board with 58mm thick were selected as the sandwich insulation layer material to study the condensation of precast concrete. The thickness of thermal insulation board is set according to the minimum requirements of the standard GB 50189—2015. The results show that there is an internal condensation problem in these precast concrete sandwich facade panels with different kinds of thermal insulation boards. But the condensation area is small. The weight of the humidity increment of 1.08%, 0.75%, 4.50% and 1.36% can meet the requirements of the standard GB 50176—1993.

    摘 要:制備了鋼纖維石墨導電混凝土,進行了電流類型及電壓大小對電阻率影響的相關試驗。研究發現,交流電源供電時,導電混凝土試件的電阻率小于直流電源供電時的電阻率,兩者的差值隨電壓的增加而減??;無論是交流電源還是直流電源供電(電壓在60V以下),試件電阻率均與電壓成反比,兩者呈二次拋物線關系,電阻率的變化幅度隨電壓的增加而減小。 Abstract:The electric conductive concrete (ECC) was prepared, the influence of current type and voltage size on the resistivity was studied by related experiments. The results showed that the resistivity of ECC under AC power is smaller than that of ECC under DC power at the same voltage. The difference between two resistivity reduces as the increasing of voltage. No matter the power supply is AC or DC, the resistivity and the ratio of resistivity are both inversely proportional to voltage.
