This article describes the construction of concrete crack control of several common methods and measures to deal with cracks on the concrete works have a certain reference value.2, classification of common cracks Concrete cracks for many reasons, the situation is more complicated, more a combination of factors. For the appearance of a crack, it is difficult to give clear reasons for an accurate analysis. Engineering practice shows that the reasons for crack formation mainly from three aspects: deformation, load and differential settlement. General by the temperature difference, shrinkage, deformation caused by differential settlement of about 80% in favor of the crack, caused by loading about 20%, etc., of course, also need to consider the comprehensive reasons. Based on these main factors, it is often summed up as cracks in the concrete shrinkage cracks, the temperature cracks, settlement cracks, creep fracture, stress fractures and cracks on the construction of several major categories.3, the crack control measures3.1 contraction (sh
