We research the causes of concrete cracking, develop the high performance anti - cracking additive, optimize the concrete mix and construction techniques, increase the stability of concrete volume by shrinkage compensation, enhance splitting tensile strength, and can meet demand of high workability of fresh concrete. in the study, a thorough investigation of this problem is made from all points of view, with the aid of various modern measurement & testing technology and different theories & methods in surface physical chemistry, structural chemistry, solid - state chemistry, composite materials, fracture mechanics, etc. our research results have shown that the various shrinkage of concrete cause concrete cracking in building engineering, such as autogenous shrinkage, dry shrinkage, temperature shrinkage, plastic shrinkage, carbonized shrinkage, etc
目前，解決混凝土開裂的方法是綜合的，我們調查研究了混凝土開裂的原因，開發研製了高性能抗裂外加劑，優化混凝土的設計和施工方法，並通過補償收縮達到混凝土體積穩定，提高抗裂強度，滿足混凝土拌和物高工作性能的要求。本研究採用多種測試技術，應用表面物理化學、結構化學、固體化學、復合材料學、斷裂力學等多學科的理論與方法，從不同的角度進行深入的研究和探討。通過調查研究建築工程中出現的混凝土開裂、滲漏問題，發現混凝土在非荷載作用下開裂主要是由混凝土的自收縮、乾燥收縮、溫度收縮、塑性收縮、碳化收縮等各種收縮變形引起的。Sodium plays a number of vital roles in the human body, contributing to the metabolizing of protein and carbohydrates, the transmission of nerve impulses, muscle contraction, hormone regulation, consumption of oxygen by cells, control of urine production, thirst, and the production of liquids ( blood, saliva, tears, perspiration, gastric juices, and bile )
鈉擔任人體維持生命所必需的角色，貢獻為蛋白質和碳水化合物的代謝、神經沖動傳輸、肌肉收縮，調節內分泌，細胞氧的消耗，控制尿的生成、乾渴，和液體（血液、唾液、眼淚、汗水、胃汁液和膽汁）的產生。Sleeves for aircraft electric cables and equipment wires - specification for fluoropolymer heat shrinkable sleeving for binding and insulation
飛機電纜和設備電線套管.第4部分:粘結和絕緣用碳氟化合物熱收縮套管規范Tensile stress will accelerate the carbonation of paste and mortar, which can be explained by the reason that shrinkage of carbonation is confined by tensile stress, and the function x = c0eantb can describe this process. carbonation can lower the total porosity and lessen the aperture in the cement paste
外部彎曲應力會加速水泥石和水泥砂漿的碳化過程，這可能與受拉區域碳化收縮受到限制有關：彎曲應力作用下水泥石和水泥砂漿的碳化動力學過程可用式x = c _ 0e ~ （ an ） t ~ b描述。The mechanism of physical damage of carbon fibers was clarified firstly. the precursor which attached on carbon fibers changes to inorganic ceramic under high temperature with large volume shrinkage which appearing at cracks with fiber traction and the cracks are mainly vertical to fiber axis. because of mismatched coefficients of thermal expansion, carbon fibers suffer multiple thermal stresses and are damaged
首次探明了碳纖維熱應力物理損傷機制，即碳纖維表面附著的先驅體在高溫下無機化形成陶瓷體，同時伴隨著大的體積收縮，在碳纖維的牽引下，基體的體積收縮以開裂形式出現，裂紋的取向以垂直於纖維軸向為主，由於碳纖維與基體熱膨脹系數失配，致使碳纖維在降溫過程中受到復雜熱應力，引起碳纖維損傷。分享友人
