普通混凝土是一種脆性材料。它的抗壓能力很強，抗拉能力卻很差。這是因為，普通混凝土本身的強度很高，但在其內(nèi)部，尤其是砂石骨料與水泥漿體之間的過渡區(qū)內(nèi)存在許多的薄弱地帶，甚至微裂紋。在受到拉力時，這些微裂紋就會迅速擴展，使得混凝土在遠低于本身強度的拉力下便會斷裂。這種原理就類似于塑料包裝袋外面的豁口，沿著豁口一撕，堅韌的包裝袋很輕易地就開了。因此，有些科學(xué)家剔除了混凝土中的普通砂子和石子，代之以極細的石英砂，并摻入較高活性的火山灰質(zhì)材料，制成活性粉末混凝土。 </p><p> 井蓋雖不起眼，但它的生存環(huán)境非常惡劣。身處馬路**，它每天都要暴露在濃重的、具有腐蝕性的汽車尾氣中，被重載的汽車反復(fù)地碾壓、振動成百上千次，而且，其下覆蓋的雨水、污水等也有較強的腐蝕性。因此，小小井蓋的工作壓力是非常大的。同時，井蓋的責任又非常重大。一旦井蓋破裂就會造成很大的安全意外，尤其一到冬天，北方積雪覆蓋的城市每年都要發(fā)生幾起行人掉進下水道的慘案。一座城市動輒有幾萬只井蓋，經(jīng)常對井蓋進行更換顯然是市政開支無法承受的。因此，井蓋必須要有很強的耐久性。你知道窨井蓋設(shè)計的時候需要注意什么嗎？</p><div

其一，這種井蓋工序少，人工成本省了下來；其二，它本身的強度高，只要很少的材料就能達到與普通混凝土相同的效果，因此非常節(jié)省材料；其三，它的耐腐蝕性能極強，一個井蓋可以用很久，這又降低了成本。后期算下來，用這種昂貴的材料做的井蓋反而劃算。重要的是，這種井蓋的內(nèi)部基本就沒有什么金屬，即使偷走了也不過是磐石一塊，真是一勞永逸地解決了井蓋被偷的問題。普通混凝土可以看作是膠凝材料將一些砂石骨料粘結(jié)在一起，砂石骨料本身是堅固的，因此發(fā)生斷裂的地點通常在粘結(jié)的過渡區(qū)域。通常使用的普通混凝土強度約為40兆帕，為花崗巖的1/5。窨井蓋哪種材料是堅固耐用的？象山高纖維窨井蓋批發(fā)</p><p

市場上我們常見的井蓋有圓形和方形，在面臨采購井蓋的時候總會遇到各種各樣的問題，窨井蓋在質(zhì)量上要求非常嚴格，畢竟關(guān)系到人們的安全，下面教你如何正確選擇。在選用這兩種形狀的井蓋時，要考慮到他們的形狀所帶來的優(yōu)勢和劣勢。使用圓形的球墨鑄鐵井蓋的主要原因，是因為圓形的直徑都是一樣長的，這樣無論井蓋怎樣翻轉(zhuǎn)，他的直徑都會比下面的井口略寬，不會掉到井里去。所以采用圓形球墨鑄鐵井蓋的，一般是市區(qū)的路政方面，它能夠較好的保護行人和車輛的安全。海曙區(qū)水泥窨井蓋多少錢</p><p
