Though in those days, travelling was not as easy as it is today, steam boats carried thousands of visitors across the Channel from Europe. On arriving in England, they were taken to the Crystal Palace by train. There were six million visitors in all, and the profits from the exhibition were used to build museums and colleges. Later, the Crystal Palace was moved to South London. It remained one of the most famous buildings in the world until it was burnt down in 1936.When he had killed the guard, the prisoner of war quickly dragged him into the bushes. Working rapidly in the darkness, he soon changed into the dead man39。Lesson82 Monster or fish? 是妖還是魚？ are washed to the shore, but they are rarely caught out at sea. Some time ago, however, a peculiar fish was caught near Madagascar. A small fishingboat was carried miles out to sea by the powerful fish as it pulled on the line. Realizing that this was no ordinary fish, the fisherman made every effort not to damage it in any way. When it was eventually brought to shore, it was found to be over thirteen feet long. It had a head like a horse, big blue eyes, shining silver skin, and a bright red tail, The fish, which has since been sent to a museum where it is being examined by a scientist, is called an oarfish. Such creatures have rarely been seen alive by man as they live at a depth of six hundred feet.The former Prime Minister, Mr Wentworth Lane, was defeated in the recent elections. He is now retiring from political life and has gone abroad. My friend, Crawley, has always been a fanatical opponent of Mr Lane39。其他城市要按照國(guó)家的統(tǒng)一部署，分期分批禁止或限制生產(chǎn)、使用實(shí)心粘土磚，并逐步向小城鎮(zhèn)和農(nóng)村延伸。各地區(qū)和有關(guān)部門要積極推廣使用新型墻體材料，凡財(cái)政撥款或補(bǔ)貼的行政機(jī)關(guān)辦公用房、公共建筑、經(jīng)濟(jì)適用房、示范建筑小區(qū)和國(guó)家投資的生產(chǎn)性項(xiàng)目等，都要執(zhí)行節(jié)能設(shè)計(jì)標(biāo)準(zhǔn)，選用和采購(gòu)新型墻體材料?！睆谋Ｗo(hù)土地，節(jié)約燃料，改善環(huán)境，造福子孫這一角度出發(fā)，用新型建材代替實(shí)心粘土磚，已成為我國(guó)建材行業(yè)的發(fā)展方向，沿用了幾千年的“秦磚漢瓦”將逐步退出歷史舞臺(tái)。我國(guó)房屋建筑材料中70%是墻體材料，其中粘土磚占據(jù)主導(dǎo)地位。尤其是一些耕地本來就十分緊缺的地區(qū)和糧食生產(chǎn)區(qū)，由于粘土磚的大量生產(chǎn)，局部地區(qū)已經(jīng)到了無土可挖、無土可用的地步，這種情況將直接影響到我們未來的生存環(huán)境。我國(guó)生產(chǎn)粘土磚每年在耗用粘土資源達(dá)13多億立方米，約相當(dāng)于毀田70萬畝的同時(shí)，每年生產(chǎn)粘土磚還要消耗7000多萬噸標(biāo)準(zhǔn)煤，排放大量的SO2，造成空氣環(huán)境污染。 ⑶發(fā)展新型墻體材料，是改善建筑功能、提高資源利用效率和保護(hù)環(huán)境的重要措施。⑷發(fā)展新型墻體材料，是美化環(huán)境，服務(wù)于我縣經(jīng)濟(jì)建設(shè)的需要。為發(fā)展循環(huán)經(jīng)濟(jì)，綜合利用，服務(wù)于民，服務(wù)于廣德縣經(jīng)濟(jì)發(fā)展，項(xiàng)目建設(shè)單位立足于廣德新型墻體材料發(fā)展的需要，著眼于廣德縣城鄉(xiāng)建筑市場(chǎng)需求，擬在桃州鎮(zhèn)白洋村章村窯廠就址改建新型墻體材料項(xiàng)目。⑵年設(shè)計(jì)能力：2000萬塊標(biāo)準(zhǔn)（20門）⑶現(xiàn)有一線工人人數(shù)：60人。第二章 項(xiàng)目建設(shè)的依據(jù)《國(guó)務(wù)院辦公廳關(guān)于進(jìn)一步推進(jìn)墻體材料革新和推廣節(jié)能建筑的通知》（國(guó)辦發(fā)[2005]33號(hào)）中華人民共和國(guó)建設(shè)部(3)燒結(jié)頁巖磚。(4)石膏砌塊。(4)輕集料混凝土條板(參照行業(yè)標(biāo)準(zhǔn)《住宅內(nèi)隔墻輕質(zhì)條板》jc/t30291995的技術(shù)要求)。(7)金屬面夾芯板(包括金屬面聚苯乙烯夾芯板、金屬面硬質(zhì)聚氨酯夾芯板和金屬面巖棉、礦渣棉夾芯板)。預(yù)制及現(xiàn)澆混凝土墻體。同時(shí)也為新型墻體材料的發(fā)展創(chuàng)造了良好的機(jī)遇。本項(xiàng)目是著眼于市場(chǎng)未來發(fā)展趨勢(shì)，以國(guó)家現(xiàn)有墻改政策為基礎(chǔ)，以科技創(chuàng)新為生產(chǎn)開發(fā)平臺(tái)，以建設(shè)、施工單位為營(yíng)銷對(duì)象，通過充分利用再生資源，根據(jù)綠色建材的要求進(jìn)行生產(chǎn)定位。5101—1998）⑸蒸壓灰砂空心磚（JC/T637—1996）砌塊⑴普通混凝土小型空心砌塊（GB698—1998）⑸蒸壓加氣混凝土砌塊（GB/T9775—1999）⑵纖維增強(qiáng)硅酸鈣板（JC/T689—1999）⑹硅鎂加氣混凝土空心輕質(zhì)隔墻板（JC623—1996）⑽住宅內(nèi)隔墻輕質(zhì)條板（JG/T在燒結(jié)普通磚砌體中，加上灰縫10mm，每4塊磚長(zhǎng)、8塊磚寬或16塊磚厚均為1m。燒結(jié)普通磚根據(jù)10塊試樣抗壓強(qiáng)度的試驗(yàn)結(jié)果，分為五個(gè)強(qiáng)度等級(jí)（表1）②不符合為不合格品。 6 177。 6 177。 6 表3 燒結(jié)普通磚的外觀質(zhì)量要求 單位：mm 項(xiàng) 目 優(yōu)等品 一等品 合格 兩條面高度差 ≤234彎曲 ≤234雜質(zhì)凸出高度 ≤234缺棱掉角的三個(gè)破壞尺寸 不得同時(shí)大于52030裂紋長(zhǎng)度 ≤a. 大面上寬度方向及其延伸至條面的長(zhǎng)度306080b. 大面上長(zhǎng)度方向及其延伸至頂面的長(zhǎng)度或條頂面上水平裂紋的長(zhǎng)度 5060100完整面② 不得少于二條面和二頂面 一條面和一頂面 － 顏色 基本一致 － － 注：①為裝飾而施加的色差，凹凸紋、拉毛、壓花等不算作缺陷。 c) 壓陷、粘底、焦花在條面或頂面上的凹陷或凸出超過2mm，區(qū)域尺寸同時(shí)大于10mm10mm。國(guó)家標(biāo)準(zhǔn)GB13544－2000《燒結(jié)多孔磚》規(guī)定，根據(jù)抗壓強(qiáng)度，燒結(jié)多孔磚分為MUMU2MUMU1MU10五個(gè)強(qiáng)度等級(jí)（見表1）。 燒結(jié)空心磚和空心砌塊燒結(jié)空心磚為頂面有孔洞的直角六面體，孔大而少，孔洞為矩形條孔（或其他孔形），平行于大面和條面，在與砂漿的接合面上，設(shè)有增加結(jié)合力的深度為1mm以上的凹線槽。表5 燒結(jié)空心磚及空心砌塊的強(qiáng)度指標(biāo) 強(qiáng)度等級(jí)抗壓強(qiáng)度平均值f≥抗壓強(qiáng)度/MPa密度等級(jí)范圍(kg/m3)變異系數(shù) ≤變異系數(shù) 抗壓強(qiáng)度標(biāo)準(zhǔn)值fk≥單塊最小抗壓強(qiáng)度fmin≥ ≤1100 ≤800對(duì)于強(qiáng)度、密度、抗風(fēng)化性及放射性物質(zhì)合格的空心磚及砌塊，根據(jù)尺寸偏差、外觀質(zhì)量、孔洞排列及其結(jié)構(gòu)、泛霜、石灰爆裂及吸水率，分為優(yōu)等品（A）、一等品（B）和合格品（C）三個(gè)質(zhì)量等級(jí)。原因：灰砂磚中的一些組分如水化硅酸鈣、氫氧化鈣等不耐酸，也不耐熱 免有流水沖刷的地方此外，原因：磚中的氫氧化鈣等組分會(huì)被流水沖失。蒸壓加氣混凝土砌塊以鈣質(zhì)材料和硅質(zhì)材料以及加氣劑、少量調(diào)節(jié)劑，經(jīng)配料、攪拌、澆注成型、切割和蒸壓養(yǎng)護(hù)而成的多孔輕質(zhì)塊體材料。 砌塊強(qiáng)度級(jí)別按100mm100mm100mm立方體試件抗壓強(qiáng)度值（MPa）劃分為七個(gè)強(qiáng)度級(jí)別。 不同質(zhì)量等級(jí)的不同表現(xiàn)密度的砌塊強(qiáng)度級(jí)別應(yīng)符合表9的規(guī)定。 普通混凝土小型空心砌塊由水泥、粗細(xì)骨料加水?dāng)嚢?，?jīng)裝模、振動(dòng)（或加壓振動(dòng)或沖壓）成型，并經(jīng)養(yǎng)護(hù)而成。用于低層和中層建筑的內(nèi)外墻。砌塊表觀密度分為：500、600、700、800、900、1200及1400等八個(gè)等級(jí)，其中，用于圍護(hù)結(jié)構(gòu)或保溫結(jié)構(gòu)的實(shí)心砌塊表觀密度不應(yīng)大于800kg/m3。其主規(guī)格尺寸為880mm380mm240mm及880mm430mm240mm兩種。 第四章 現(xiàn)狀和市場(chǎng)發(fā)展趨勢(shì)分析新型墻體材料主要是用混凝土、水泥或粉煤灰、煤矸石等工業(yè)廢料和生活垃圾生產(chǎn)的非黏土磚、建筑砌塊及建筑板材。 我國(guó)建筑材料行業(yè)流行著3個(gè)70%的說法,即房建材料的70%是墻體材料；墻體材料的70%是實(shí)心黏土磚；而建筑行業(yè)節(jié)能的70%有賴于墻體材料的改革。的資源、自然條件、工業(yè)和科學(xué)技術(shù)水平、建筑風(fēng)格、民族習(xí)俗等方面的影響。國(guó)外墻體材料在遵循保護(hù)環(huán)境、節(jié)約能源、合理利用資源、發(fā)展綠色產(chǎn)品的基礎(chǔ)上，根據(jù)本國(guó)的情況各有側(cè)重。有加氣條板、混凝土砌塊,灰砂磚及燒結(jié)制品、石膏砌塊,輕質(zhì)墻板等。如加氣混凝土,國(guó)內(nèi)規(guī)模大的生產(chǎn)線(年產(chǎn)20萬m3主要為混凝土多孔磚，產(chǎn)品結(jié)構(gòu)單一，企業(yè)規(guī)模小，產(chǎn)品質(zhì)量不穩(wěn)定，技術(shù)力量薄弱，裝備水平不高；在應(yīng)用方面，由于新型墻體材料應(yīng)用技術(shù)未能配套和普及，施工隊(duì)伍沒有熟練地掌握新型墻體材料的施工工藝。12石膏制品以紙面石膏板為主，增長(zhǎng)迅速；開發(fā)各種新的制磚技術(shù)，如垃圾磚生產(chǎn)技術(shù)，蒸壓粉煤灰磚生產(chǎn)技術(shù)，燒結(jié)粉煤灰磚生產(chǎn)技術(shù)，泡沫磚生產(chǎn)技術(shù)等。第四節(jié) 廣德市場(chǎng)前景分析據(jù)預(yù)測(cè)，十一五時(shí)期我縣房地產(chǎn)業(yè)將獲得前所未有的發(fā)展，到2010萬m2按照可持續(xù)發(fā)展的戰(zhàn)略部署，國(guó)家將禁止使用(乃至生產(chǎn))日前禁止使用黏土磚，十一五期間將淘汰4萬家黏土實(shí)心磚企業(yè)。主、輔設(shè)備第二節(jié) 建設(shè)規(guī)模該項(xiàng)目年設(shè)計(jì)能力為：年生產(chǎn)新型墻體磚3000萬塊（折合標(biāo)準(zhǔn)磚），總建筑面積（不含道路和場(chǎng)地）2030㎡。第六章 設(shè)備選型 本項(xiàng)目根據(jù)新型墻體材料生產(chǎn)實(shí)際需要，選擇先進(jìn)的工藝設(shè)備。s son, Donald, also set up a world record.
