【正文】 響混凝土塑性收縮開裂的主要因素有水灰比、混凝土的凝結(jié)時(shí)間、環(huán)境溫度、風(fēng)速、相對(duì)濕度等等。 45176。五是在凍土上搭設(shè)模板時(shí)要注意采取一定的預(yù)防措施。高溫膨脹引起的混凝土溫度裂縫是通常中間粗兩端細(xì)，而冷縮裂縫的粗細(xì) 變化不太明顯。七是高溫季節(jié)澆筑時(shí)可以采用搭設(shè)遮陽(yáng)板等輔助措施控制混凝土的溫升，降低澆筑混凝土的溫度。十四是混凝土中配置少量的鋼筋或者摻入纖維材料將混凝土的溫度裂縫控制在一定的范圍之內(nèi)。通常的預(yù)防措施有：一是保證鋼筋保護(hù)層的厚度。通常的處理措施是在裂縫的表面涂抹水泥漿、環(huán)氧膠泥或在混凝土表面涂刷油漆、瀝青等防腐材料， 在防護(hù)的同時(shí)為了防止混凝土受各種作用的影響繼續(xù)開裂，通常可以采用在裂縫的表面粘貼玻璃纖維布等措施。常用的置換材料有：普通混凝土或水泥砂漿、聚合物或改性聚合物混凝 土或砂漿。t 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 lot of and have already transformed to cause of crack:Such as temperature variety, constringency, inflation, the asymmetry sink to sink etc. reason cause of crack。Perhaps because of template just degree shortage, the template propped up to once be apart from big or prop up bottom loose move etc. to cause, especially at winter, the template prop up at jelly soil up, jelly the soil turn jelly empress creation asymmetry to sink to decline and cause concrete structure creation kind crack many is deep enter or pierce through sex crack, it alignment have something to do with sinking to sink a circumstance, general follow with ground perpendicular or present 30 176。t have the surface crack of influence and deep enter crack of processing measure that is usually is a surface in crack daubery cement syrup, the wreath oxygen gum mire or at concrete surface Tu2 Shua paint, asphalt etc. antisepsis material, at protection of in the meantime for keeping concrete from continue under the influence of various function to open crack, usually can adoption the surface in crack glue to stick glass fiber cloth etc. measure. Infuse syrup, the Qian sew method Infuse a syrup method main the concrete crack been applicable to have influence or have already defend Shen request to the structure whole of repair, it is make use of pressure equipments gum knot the material press into the crack of concrete, gum knot the material harden behind and concrete formation one be whole, thus reinforce of in mon use gum knot material has the cement the syrup, epoxy, A Ji C Xi sour ester and gather ammonia ester to equalize to learn material. The Qian sew a method is that the crack be a kind of most in mon use method in, it usually is follow the crack dig slot, the Qian fill Su in the slot or rigid water material with attain closing crack of in mon use Su material has PVC gum mire, plastics ointment, the D Ji rubber etc.。s etc. overlay, and attention sprinkle water to protect, appropriate extension protect time, assurance the concrete surface be slowmoving cool off. At the cold season, concrete surface should constitution heat preservation measure, in order to prevent cold wave is the allocation be a little amount in the concrete of reinforcing bar perhaps add fiber material concrete of temperature crack control at certain of scope inside. Crack and prevention that the chemical reaction cause 2021級(jí)工程管理專業(yè)英語(yǔ)科技文獻(xiàn)翻譯 13 Alkali bone39。s much presenting in the center breadth, both ends be in the centerthin and the length be different, with each other not coherent crack general long 2030 cm, the longer crack can reach to a 23 m, breadth 15 creation of main reason is:The concrete is eventually almost having no strength or strength before the Ning very small, perhaps concrete just eventually Ning but strength very hour, be subjected to heat or pare strong wind dint of influence, the concrete surface lose water to lead quick, result in in the capillary creation bigger negative press but make a concrete physical volume sharply constringency, but at this time the strength of concrete again can39。 參考文獻(xiàn) [1] 吳潔 楊天春 . 建筑施工技術(shù) [M].中 國(guó)建筑工業(yè)出版社 .2021年 5月第 1版 .

Key word: Concrete crack prevention processing 1 Foreword Concretes is a kind of anticipate by the freestone bone, cement, water and other mixture but formation of the in addition material of quality brittleness not and all material. Because 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 make the concrete present one some not and all the characteristic of quality. The 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 endanger. But after the concrete be subjected to lotus carry, difference in temperature etc. 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 existence and development usuall
