This paper summarizes the concrete development present situation, has analyzed the concrete internal since there exist a temperature gradient and humidity produced stress caused by cracking phenomena, and put forward the concrete cracking could prevent the effective measures.混凝土开裂的原因Concrete cracking reasons  混凝土早期裂缝产生是因为混凝土的收缩变形与混凝土弹性模量和抗拉强度不相适应产生的。混凝土的早期收缩包括:塑性阶段的收缩和硬化初期的水化热冷缩与干燥收缩两部分。塑性收缩是由泌水沉降引起的。当收缩受到约束时,产生内拉应力,由混凝土断面上湿度分布的梯度引起内应力。湿度梯度越大,内应力就越大,最大拉应力在混凝土表面,收缩变形乘以弹性模量大于抗拉强度时开裂。混凝土硬化过程中,弹性模量和抗拉强度都增长,弹性模量增长的速度大于抗拉强度增长速度时,就容易开裂。同样,混凝土水化产生温度梯度也产生相同方向的应力,由于现在的水泥中 C 3 S 和 C 3 A 的含量比过去的高,所以水化热也较大,即使普通的梁板结构也不能忽视温度梯度和湿度梯度的影响。综合上述,早期裂纹取决于混凝土内部的湿度梯度与温度梯度,收缩值、弹性模量与抗拉强度增长速度。  Early concrete cracks because concrete's shrinkage deformation and concrete elastic modulus and tensile strength does not adapt produces. Concrete shrinkage include: the early stage of plastic shrinkage and hardening of the early hydration heat and cold and dry shrinkage two parts. The plastic shrinkage is caused by secrete water settlement. When contraction restrained within that arise when tensile stress and by concrete section on the distribution of stress in moisture gradient. Humidity gradient is larger, the greater the internal stress, the maximum tensile stress in the concrete surface, contraction deformation multiplied by elastic modulus is greater than tensile strength when craze. Concrete sclerotic process, elastic modulus and tensile strength is growing, elastic modulus growth faster than tensile strength growth, it is easy craze. Similarly, concrete hydration produce temperature gradient also produce the same direction of stress, because now in cement C 3 S and C three A's content than the previous high, so the hydration heat is larger also, if the common beam slab structure also cannot ignore temperature gradient and humidity gradient effect. A combination of the early cracks of concrete, depends on the humidity of gradient and temperature gradient and shrinkage and the elastic modulus and tensile strength growth.防止混凝土开裂的措施Prevent concrete cracking measures  通过对混凝土开裂原因的分析,得出防止混凝土开裂的措施主要有三条,第一是在保证混凝土强度的前提下,原材料的品种选用及配合比设计原则应是最大限度地降低水化热及推迟水化热峰出现的时间,减少温度梯度,降低温度应力。可以通过采用等量取代水泥的膨胀剂,粉煤灰掺合料,正确选用粗集料等措施。第二采用良好保温措施,控制混凝土表面与空气间湿度差;采用饱水性微集料,控制混凝土内部的相对湿度梯度,减少自收缩应力。第三采用在混凝土中加入适量纤维的方法,这能有效地改善混凝土的抗拉、抗弯性能,提高混凝土的韧性和抗冲击性能,并有效改善混凝土的抗裂性能。  Through the analysis of the reason of concrete cracking, it is concluded that prevent concrete cracking of measures mainly has three, the first is guaranteed to the strength of concrete under the precondition of raw material breed selection and the principle of mix design should be minimized hydration heat and delay the hydration heat peak appearing time, reduce the temperature gradient, reduce the temperature stress. Can by adopting isometric substitute of expansive agent, fly ash cement admixture, the correct choice of coarse aggregate etc. The second use of good insulation measures to control the concrete surface between with air humidity poor. Adopts full water-borne micro aggregate concrete, control the relative humidity gradient, reduce autogenous shrinkage stress. Article adopted in concrete adding appropriate fiber methods, which can effectively improve the concrete tensile strength, flexural performance, improving the concrete toughness and shock resistance, and effectively improve anti-cracking performance of concrete.通过以上分析,采用下述方法克服混凝土开裂,从而提高混凝土的质量。Through the above analysis, adopt the following ways to overcome concrete cracking, so as to improve the quality of concrete.(1)在混凝土中掺入膨胀剂(1) in the concrete mixing expansive agent  在混凝土中掺入适量的膨胀剂,利用约束条件下膨胀变形来弥补混凝土的收缩变形,抵消混凝土结构在收缩过程中产生的全部或大部分的拉应力,使混凝土的抗裂应力大于混凝土在约束状态下,因温度收缩、化学收缩、干燥收缩和较高的早期弹性模量而产生的内部应力,从而防止混凝土开裂。煅烧 CaO 是气硬性胶凝材料,具有在空气中硬化并产生适应膨胀的特性,要以部分抵补因钙矾石水养护不足产生的收缩,并提高各龄期强度。  In concrete adding appropriate amount of the expansive agent, using the constraint condition of concrete expansive deformation to compensate for the systole, offset concrete structure in the process of shrinking generated in all or most of the tensile stress, concrete crack stress is more than concrete in the constraint condition, because the temperature shrinkage, chemical shrinkage, drying shrinkage and higher early elastic modulus and produce the internal stress, so as to prevent concrete cracking. Calcination CaO is gas rigid cementitious material, have in air sclerosis and generate adapt to the characteristics of expansion, want to be part of offset for ettringite water maintenance deficiencies produce contraction, and improve in all ages intensity.  在膨胀组分中引入煅烧的 MgO 对抑制混凝土的后期收缩,防止开裂有其独特的益处。 MgO 较好的后期微膨胀性能,在一定程度上弥补了水泥硬化后体积收缩缺陷,增强混凝土的抗裂能力。因此,在膨胀组分中掺入适量煅烧 CaO 和 MgO 办法来抑制混凝土的开裂,使这三种组分适当组合,取长补短从而获得适宜的膨胀量和膨胀能,能较好地补偿混凝土结构工程的收缩开裂。  In introducing the calcination expansion components to restrain MgO style of concrete shrinkage, prevent craze later has its unique benefits. MgO style better late micro expansion performance, makes up for in some degree after hardened cement volume contraction defects, enhance the concrete the anti-cracking ability. Therefore, in inflation component of adding appropriate calcination CaO and MgO style measures to curb concrete crack, make the three components of the right combination and complement each other so as to achieve the suitable expansion amount and expansion can, they can better compensation concrete structure project shrinkage cracking.(2)在混凝土中掺入膨胀剂和粉煤灰(2) in the concrete mixing expansive agent and fly ash  粉煤灰与膨胀剂同时掺和,能改善硬化混凝土的孔结构,使大孔减少,微孔增多,使孔级配更加合理,减少由蒸发生成孔内部负压产生的收缩力,同时粉煤灰中含有活性的 SiO 2 与 A1 2 O 3 ,他们与水泥的水化产物 Ca(OH) 2 ,形成水泥硅酸钙与水化铝酸凝胶体,这两种凝胶体对混凝土 Ca(OH) 2 强度和密实度的贡献均比较强,能大幅度提高混凝土的后期强度。  Fly ash and expansive agent simultaneously adulterating, can improve hardening of concrete pore structure, make macroporous reduce, microporous increased, make pore gradation more reasonable, reduce by evaporation generation hole internal negative pressure generated contraction forces, and fly ash contained in the activity of the SiO 2 and A1 2 O 3, they and cement hydration products Ca (OH) 2, forming calcium silicate cement hydration aluminates gels, with the two gels of concrete Ca (OH) 2 strength and compactness contributions are relatively strong, can greatly improve the post strength of concrete.  粉煤灰和膨胀土同时使用,在水泥水化初期,粉煤灰微粉分布并包裹在水泥颗粒的表面,起到了延缓和减少水化初期的水化作用,降低早期和总的水化热,这样较容易控制混凝土的内部温差,膨胀剂的膨胀作用可以补偿混凝土的后期冷缩和干缩,降低混凝土的收缩变形,抵消了混凝土结构在收缩过程中产生的大部分的拉应力,从而达到防止混凝土开裂的目的。  Fly ash and expansive soil use at the same time, in the initial stage, fly ash cement hydration micro-powder distribution and wrapped in cement particle surface, played a delay and reduce early hydration, reduce early hydration function and total hydration heat, so more easily control the internal temperature of concrete expansive agent can compensate the expansion effect of concrete cold and dry shrinkage later, reduce the concrete's shrinkage deformation, offsetting concrete structure in the process of shrinking generated in most of the tensile stress, achieve prevent concrete cracking of purpose.(3)在混凝土中掺入膨胀剂和纤维(3) in the concrete mixing expansive agent and fiber  为了克服单一膨胀剂的缺陷,在混凝土中引入聚丙烯纤维。由于膨胀剂在水泥水化产物发生足够数量的钙矾石膨胀源,并在限制膨胀的条件下产生内部膨胀应力来抵消由于体积收缩产生破坏性拉应力,从而达到预防开裂的目的。虽然膨胀剂对防止早期开裂具有重要作用,、但对后期开裂作用微乎其微,而聚丙烯纤维是在混凝土强度提高到一定程度,使纤维与混凝土基体间有足够的握裹强度,从而起到相应防裂作用。这是由于纤维以单位体积内较大数量均匀分布于混凝土内部,在微裂开始形成时,必然遭到纤维所产生的弹性应力的阻挡,消耗能量,使微裂难以进一步发展。  In order to overcome the defects of single expansive agent in concrete, introduction of polypropylene fiber. Because expansion agent in the cement hydration products happened a sufficient number of ettringite expansion sources, and the restricted expansion conditions produce internal stress to offset due to expansion volume contraction devastating tensile stress cracking, so as to achieve the purpose of prevention. Although expansive agent to prevent early-cracking plays an important role, but to little effect, and later cracking in concrete strength polypropylene fiber is raised to a certain degree, fibre and concrete matrix between have enough grip bond strength, thus plays corresponding crack-proof role. This is because fiber with per unit volume larger Numbers evenly among concrete interior, in micro cracked begin to form, the inevitable by fiber produced by elastic stress and preventing, energy consumption, make the micro cracked difficult to further development.(4)在混凝土中掺入膨胀剂同时对混凝土进行微养护(4) in concrete mixing expansive agent simultaneously on the concrete micro curing  高性能混凝土在工程应用中最大障碍是早期的开裂问题,这时混凝土通常水泥用量大,水泥水化过程产生化学收缩,在水泥浆体中形成空隙,导致内部相对应湿度降低和自收缩,致使混凝土结构开裂,因此对于高性能混凝土在加强对外部湿养护的同时,还应进行内部养护,其中包括利用适量饱水集料提供微养护所需的水分。  High-performance concrete in engineering application of biggest obstacle is early cracking problem, then concrete usually dosage of cement, cement hydration processes produce chemical contraction, in the slurry formation, resulting in internal gaps correspond humidity is reduced and autogenous shrinkage of concrete structure, causing cracking, so for high-performance concrete in strengthen the external wet maintenance of time, we should carry on the internal maintenance, including using ShuiJi materials provide adequate satisfied micro necessary conservation of water.  轻集料为烧结熔融材料,其中分布着直径 10 ~ 100μm 近似球形的孔,提高内部相对湿度,对于促使水泥达到最大水化程度,防止混凝土结构早期开裂具有重要作用。在混凝土中掺入膨胀剂,抵消混凝土结构在收缩过程中产生的部分应力,并与微养护相结合,可以有效预防混凝土开裂。  Lightweight aggregate for sintering molten material, including distributed the diameter of10 ~ 100μm approximate spherical hole, improve internal relative humidity, for motivating cement hydration to achieve maximum extent, prevent concrete structure early-cracking plays an important role. In the concrete mixing expansive agent in concrete structure shrinkage and offset produces in the process of stress, and micro part maintenance unifies, can effectively prevent concrete cracking.
