1、土木工程外文翻译建筑施工混凝土裂缝的预防与处理土木工程外文翻译建筑施工混凝土裂缝的预防与处理 翻译原文 Building construction concrete crack of prevention and processing Abstract The crack problem of concrete is a widespread existence but again difficult in solve of engineering actual problem this text carried on a study analysis to a little bit fami

2、liar crack problem in the concrete engineering and aim at concrete the circumstance put forward some prevention processing measure Keyword Concrete crack prevention processing Foreword Concretes ising 1 kind is anticipate by the freestone bone cement water and other mixture but formation of the in a

3、ddition material of quality brittleness not and all materialBecause the concrete construction transform with oneself control etc a series problem harden model of in the concrete existence numerous tiny hole spirit cave and tiny crack is exactly because these beginning start blemish of existence just

4、 make the concrete present one some not and all the characteristic of qualityThe tiny crack is a kind of harmless crack and accept concrete heavy defend Shen and a little bit other use function not a creation to endangerBut after the concrete be subjected to lotus carry difference in temperature etc

5、 function tiny crack would continuously of expand with connect end formation we can see without the aid of instruments of macro view the crack be also the crack that the concrete often say in the engineering Concrete building and Gou piece usually all take sewer to make of because of crack of existe

6、nce and development usually make inner part of reinforcing bar etc material creation decay lower reinforced concrete material of loading ability durable and anti- Shen ability influence building of external appearance service life severity will threat arrive peoples life and property safetyA lot of

7、all of crash of engineerings is because of the unsteady development of the crack with the result thatModern age science research with a great deal of of the concrete engineering practice certificate in the concrete engineering crack problem is ineluctable also acceptable in certainly of the scope ju

8、st need to adopt valid of measure will it endanger degree control at certain of scope insideThe reinforced concrete norm is also explicit provisionSome structure at place of dissimilarity under the condition allow existence certain the crack of widthBut at under construction should as far as possibl

9、e adopt a valid measure control crack creation make the structure dont appear crack possibly or as far as possible decrease crack of amount and width particularly want to as far as possible avoid harmful crack of emergence insure engineering quality thus Concrete crack creation of the reason be a lo

11、tiation to treat in the actual engineering work皂ut a problem according to the actual circumstance In the concrete engineering the familiar crack and the prevention 1Stem Suo crack and prevention Stem the Suo crack much appear after the concrete protect be over of a period of time or concrete sprinkl

12、e to build to complete behind of around a weekIn the cement syrup humidity of evaporate would creation stem Suo and this kind of constringency is cant negativeStem Suo crack of the creation be main is because of concrete inside outside humidity evaporate degree dissimilarity but cause to transform d

13、issimilarity of resultThe concrete is subjected to exterior condition of influence surface humidity loss lead quick transform bigger inner part degree of humidity variety smaller transform smaller bigger surface stem the Suo transform to be subjected to concrete inner part control creation more big

14、pull should dint but creation crackThe relative humidity is more low cement syrup body stem Suo more big stem the Suo crack be more easy creationStem the Suo crack is much surface parallel lines form or the net shallow thin crack width many between 005-02 mm the flat surface part much see in the big

15、 physical volume concrete and follow it more in thinner beam plank short to distributeStem Suo crack usually the anti- Shen of influence concrete cause the durable of the rust eclipse influence concrete of reinforcing bar under the function of the water pressure dint would creation the water power s
