本文首先簡要介紹了溶膠?凝膠理論和技術的歷史背景、基本工藝過程及特點，並著重評述了溶膠?凝膠技術在制備塊狀、纖維、薄膜與塗層、粉末和復合材料方面的最新研究進展及其應用；採用溶膠?凝膠法與水置換法制備了尺寸較大的sio _ 2 - zro _ 2系玻璃-陶瓷，採用分步水解法制備了摻釹sio _ 2 - al _ 2o _ 3激光玻璃-陶瓷。Next was an experimental study on modification of stone ballast concrete small hollow block. the influence of polypropylene fiber, expansion agent and both of them on permeability - resistance and both moisture expansion and dry shrinkage of the block were systematically tested. the testing results and theoretical analysis slowed that they all can improve its properties, among which polypropylene fiber can most effectively restrain it ’ s moisture expansion and drying shrinkage ; however, the block doubly blended with polypropylene fiber and expansion agent will be likely to most beneficially improve crack - resistance of wall filled with the block
試驗結果和理論分析表明，單摻聚丙烯纖維、單摻膨脹劑和雙摻聚丙烯纖維與膨脹劑均能改善混凝土空心砌塊的性能，其中，聚丙烯纖維更有利於限制單個砌塊的濕漲干縮，單摻聚丙烯纖維的空心砌塊濕脹干縮的波動性最小;雙摻聚丙烯纖維與膨脹劑對限制石渣砌塊濕脹干縮的效果不理想，但雙摻砌塊將更有利增強于砌塊填充墻的整體抗裂性。The data used in the ann model are arranged in a format of 8 input parameters that cover the compressive strength, tensile strength and width of cube concrete ; the thickness, the width, the bond length and the elastic modulus of the cfrp plate. 15 sets of experimental data are used for predicting
神經網路的建立考慮了碳纖維布的厚度、寬度、粘結長度、彈性模量、抗拉強度和混凝土試塊抗壓強度、抗拉強度、寬度這8個參數，運用了118組試驗數據對網路進行訓練，對15組數據進行了預測分析。The influence of polypropylene fiber, expansion agent and both of them on moisture expansion and dry shrinkage of the filled wall were systematically tested. the testing results and theoretical analysis slowed that polypropylene fiber was the most beneficial to restrain it ’ s moisture expansion and drying shrinkage, however, the block doubly blended with polypropylene fiber and expansion agent can most beneficially improve crack - resistance of wall filled with the stone ballast block, at the
試驗結果和理論分析證明上述試驗結果及理論分析，即單摻聚丙烯纖維、單摻膨脹劑和雙摻聚丙烯纖維與膨脹劑均能限制混凝土空心砌塊的濕漲干縮，其中，聚丙烯纖維的限制效果最好;但是，膨脹劑的補償收縮與聚丙烯纖維的限縮聯合作用使得雙摻砌塊更有利於增強混凝土空心砌塊填充墻的整體抗裂性能。If stone ballast block blended with shrinkage - reducing agent, polypropylene fiber and expansion agent can reduce its own shrinkage while can ’ t worsen its own other properties, it is undoubted that modification of stone ballast block is beneficial to prevent crack in wall filled with stone ballast block, because these modification materials can respectively reduce, restrain and compensate shrinkage of concrete
在混凝土砌塊中摻加減縮劑、聚丙烯纖維和膨脹劑等減縮、限縮和補償收縮材料如能降低砌塊的收縮率，且不劣化砌塊的其它性能，則無疑有利於砌塊墻體的開裂防治。首先進行砌塊材料的改性試驗研究。The main research outputs of this paper are as follows : l. baed on the choosing rational mix proportion, the influence of changing volume proportion of steel fiber on mechanical properties such as crushing resistance, splitting resistance, breaking resistance and bending resistance and the variation rule of mechanical properties are studied by experiment and theoretical analysis of 320 samples. according to experimental results of different layered structure of fiber - reinforced concrete, the influence of layered height on splitting strength and breaking strength is discussed. so it offers reliable reference to design road structure by using fiber - reinforced concrete
在選擇了合理的配合比基礎上，通過對320塊試件的試驗和理論分析，研究了鋼纖維體積率的變化對抗壓、劈拉、抗折以及彎曲韌性等力學性能的影響及變化規律，由不同分層試件的試驗結果，探討了鋼纖維混凝土的分層高度對劈拉、抗折等強度影響，為鋼纖維混凝土的路面結構設計提供了可靠的依據。Through the small specimen tests, we found the failure of the bonding interface between frp and concrete can be avoided and the efficiency can be highly improved, as long as the pressure is almost 0. 2 kg / cm2
開展小試塊粘結加壓實驗研究，結果表明只要施加0 . 2kg / cm ~ 2左右的接觸壓就能避免發生纖維與混凝土之間的脫膠破壞，大幅提高加固效率。分享友人
