What is the antifreeze type grouting material deformation and cracking? - Chongqing grouting material manufacturers

Chongqing grouting chongqing grouting material manufacturer the grouting material price & # 8195;   Resistance of high strength self-leveling grouting frozen type grouting material in elastic and inelastic deformation under load when presented; When the bear loads due to all kinds of present contraction deformation, when grouting material received constraints, shrinkage strain will lead to complex stress models, cracking of grouting material.     Chongqing grouting material in the condensation will produce a certain amount of volume deformation hardening process. This means that the hardening of the grouting material in addition to the load deformation, in the absence of loads, various physical or chemical factors can also lead to the volume of the grouting material or partial volume changes, which appear to be out of shape.     If chongqing grouting material in the constraint condition of freedom, then the volume change general won't produce adverse effect. However, actual use of antifreeze type grouting material structure will contain by foundation, reinforced or adjacent components, in varying degrees of constraint condition. Even if a single grouting material block not restricted by external, the phase of its internal components are restricted each other between mixing grouting material is what segregation, and therefore is still in the constraint condition. Therefore, the volume change of grouting by the action of the constraint in the grouting material internal stress is produced.       Chongqing grouting material to withstand high grouting material construction offer compressive stress, and its tensile strength is lower, generally does not exceed 10% of the compressive strength. In theory, under the condition of fully controlled, antifreeze type grouting material internal tensile stress is produced to achieve 3 mpa to 10 mpa, so, for the constrained the grouting material, excessive volume change of tensile stress once more than its tensile strength, it could cause antifreeze type grouting material craze, cracks. Crack not only influence the grouting material under design load capacity, but also seriously damage the durability and appearance of the grouting material.
