中文拼音 [méikǒngxìlǜ]
煤孔隙率
英文
coal porosity-
Abstract : basic stuff of sinter flyash ceramisite is flyash and clay as agglomerant. the si nter flyash ceramisite is of dense in structure, low porosity which can improve t he mechanical properties of the material. it has properties such as high strong a nd low absorption of water and better stability. it is a new type ofbuliding mate rial
文摘:燒結型粉煤灰陶粒的主要原料是粉煤灰和作為粘結劑的粘土，文中所述燒結粉煤灰陶粒結構緻密，孔隙率低，能較好地改善了材料的力學性能，具有高強、吸水率低、穩定性好等特點，是一種新型建築材料The result shows that the compressive strength of concrete under natural variational low temperatural curing is higher than the compressive strength of concrete under permanent low temperatural curing and the pore porosity under natural variational low temperatural curing is less than the compressive strength of concrete under permanent low temperatural curing ; the compactibility of concrete is good with fa ( < 15 % ) and sf ( < 8 % )
結果當摻合料摻量相同時，自然變低溫（ - 15 ~ 5 ）養護條件下混凝土抗壓強度高於恆低溫（ - 10 ）養護條件下混凝土抗壓強度，孔隙率要低於恆低溫（ - 10 ）養護條件下混凝土的孔隙率;當單摻粉煤灰時摻量低於15 % 、單摻硅灰時摻量低於8 % ，低溫混凝土的密實性較好。Based on the principle, the preventive scheme was put forward by stage and combining water infusion with grouting
給出了該條件下增加煤體孔隙率，減少瓦斯、空氣流通通道的防治原則。The result indicated that, mix the mineral mixture of fly ash, flag into concrete can optimize the concrete pore structure, improve the concrete compressive strength and impermeability, and along with the age increment the improvement become more obviously ; after saturated freezing and thawing, the concrete pore structure changed apparently, total porosity increased, macro porous quantity rapid increased, small pore quantity reduced, mean radius and most probable aperture increased ; and the more saturated degree, the more obviously destructive effect
研究表明:在混凝土中摻加粉煤灰、礦渣等礦物摻合料優化了混凝土的孔結構，提高了混凝土的抗壓強度和抗滲性能，且隨齡期的延長這種改善作用更加明顯;飽水凍融后混凝土的孔結構變化明顯，總孔隙率增加，大孔數量急劇增大，小孔數量減小，平均孔徑和最可幾孔徑增大;且飽水程度越大，這種破壞作用越明顯。This paper consists of the following parts : firstly, the physical properties ( particle size distribution, specific area, porosity ratio and pore volume ) and pyrolysis characteristics have been studied in experiments with four kinds of coals. according to experimental results, the advantages of combustion characteristics of micro - pulverized caols are analysed on the theory. secondly, the reconstructing plan is designed in details for a conventional system of the hot air transferring pulverized coal to reduce nox emission
本文主要包括以下內容：首先，通過基礎的實驗分別對四種具有代表性煤種一、三次風所含煤粉的物理特性（粒徑分佈、孔隙率、孔容積和比表面積）和熱解特性進行研究，從理論上分析煤粉細化后，較細顆粒（即三次風含粉）在燃燒特性上的優越性，為三次風含粉用於再燃燃燒打下基礎。Determination of apparent relative density and porosity of industrial briquette
