【正文】 能，而且會(huì)引起鋼筋的銹蝕，混凝土的碳化，降低材料的耐久性，影響建筑物的承載能力，因此要對混凝土裂縫進(jìn)行認(rèn)真研究、區(qū)別對待，采用合理的方法進(jìn)行處理，并在施工中采取各種有效的預(yù)防措施來預(yù)防裂縫的出現(xiàn)和發(fā)展，保證建筑物和構(gòu)件安全、穩(wěn)定地工作。t Suo crack of the creation be main is because of concrete inside outside humidity evaporate degree dissimilarity but cause to transform dissimilarity of result:The 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 pull should dint but creation relative humidity is more low, cement syrup body stem Suo more big, stem the Suo crack be more easy the Suo crack is much surface parallel lines form or the shallow thin crack, width many between mm, the flat surface part much see in the big physical volume concrete and follow it more in thinner beam plank short to 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 split crack influence concrete of loading dint etc..Concrete stem the Suo be main with water ash of the concrete ratio, the dosage of the position, cement of cement, gather to anticipate of the dosage of the property and dosage, in addition etc. relevant. Su constringency crack Su constringency is the concrete is before condense, surface because of lose water quicker but creation of Su constringency crack is general at dry heat or strong wind the weather appear, crack39。t resist its constringency, therefore creation influence concrete Su constringency open the main factor of crack to have water ash ratio, concrete of condense time, environment temperature, wind velocity, relative humidity...etc.. to sink crack The creation which sink to sink crack is because of the structure foundation soil quality not and evenly, loose soft or return to fill soil dishonest or soak in water but result in the asymmetry sink to decline with the result that。s 45 176。The size bigger structure of the beam plank length, the crack run parallel with short side more。s anticipating the crack that
