KeywordKeywordConcrete crack prevention processing Foreword Concretes ising 1 kind is anticipate by the freestone bone, cement, water and other mixture but ation of the in addition material of quality brittleness not and all material.Because the concrete construction trans 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 ation 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 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 safety.A lot of all of crash of engineerings is because of the unsteady development of the crack - 1 - 山东建筑大学毕业设计外文文献及翻译 with the result that.Modern age science research with a great deal of of the concrete engineering practice certificate, in the concrete engineering crack problem isineluctable, also acceptable in certainly of the scope just need to adopt valid of measure will it endanger degree control at certain of scope inside.The reinforced concrete norm is also explicit provisionSome structure at place of dissimilarity under the condition allow existence certain the crack of width.But at under construction should as far as possible 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 lot of and have already transed to cause of crackSuch as temperature variety, constringency, inflation, the asymmetry sink to sink etc. reason cause of crack;Have outside carry
