摘要根據荊州長江公路大橋預應力混凝土結構設計、施工要求，采用摻入超細摻和料和高能外加劑配制c60混凝土，長距離、大高度泵送混凝土，為大橋建設加快進度，確保質量起到了作用。 - 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(fā)研制了高性能抗裂外加劑，優(yōu)化混凝土的設計和施工方法，并通過補償收縮達到混凝土體積穩(wěn)定，提高抗裂強度，滿足混凝土拌和物高工作性能的要求。本研究采用多種測試技術，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。通過調查研究建筑工程中出現的混凝土開裂、滲漏問題，發(fā)現混凝土在非荷載作用下開裂主要是由混凝土的自收縮、干燥收縮、溫度收縮、塑性收縮、碳化收縮等各種收縮變形引起的。 - It is high performance concrete of low water - binder ratio . with its own gravity and without any vibration , it can fill up the space automatically . with high adding quantity of fly ash and slag , high quality water reducing agent and other compound admixture is the most important technology of this kind of high performance concrete . scc focus on high workability at the same time on high strength and high durability through choosing the composite of aggregate , additives , content of cementions material , admixture reasonably and the optimum design of mix proportion
本文研究了采用吉林省本地原材料和常規(guī)生產工藝配制c40自密實混凝土的制作技術,采用水膠比、粉煤灰摻量、砂率、膠凝材料總量四個因素進行配合比的正交設計,試驗分析了自密實混凝土拌合物的工作性以及硬化后的力學性能、耐久性和生產與施工注意事項,并對其經濟性做出了客觀評價,本次試驗為吉林地區(qū)自密實混凝土的推廣應用提供了數據基礎。 - Because of its high strength , high workability , high volume stability and high anti - permeability , hsc ( high strength concrete ) has been widely used throughout the world as a new generation structure material . but due to its low ductility , seldom has it been used in the protective engineering
高強混凝土具有高強度、高工作度、高體積穩(wěn)定性、高抗?jié)B性等優(yōu)良性能，作為新一代建筑材料在國際范圍內得到了廣泛應用，但是由于高強混凝土的延性較差，未能在防護工程中得到大量使用。 - It's difficult to see high workability in a sentence. 用high workability造句挺難的
