Age - the influence of the strength of CGM high-strength grouting material How many tons of grouting material a cubic

CGM high-strength grouting CGM high-strength grouting material manufacturer CGM high-strength grouting density CGM high-strength grouting material under the condition of moisture curing zhengzhou grouting material, for the same kind of cement grouting material or the same curing age, the strength of the CGM high-strength grouting material is inversely proportional to the ratio of water. CGM high-strength, however, the strength of grouting material and adhesive empty than the relationship between the more obvious, thus using more extensive, mainly because the amount of gel to show the total amount of grouting material in cement materials, is close to the cement type and curing age, at the same time.     In actual CGM high-strength grouting materials engineering, strength assessment of CGM high-strength grouting material on keep raising the strength of 28 d shall prevail, and many other performance of CGM high-strength grouting material has a lot to do with the 28 d strength performance. Not very important scientific basis. In an early stage hydration, the strength of the CGM high-strength grouting material development is slow, the cement hydration is not fully, and fail to reflect the real strength of grouting material; And age too late, although the cement hydration is completely, but it will delay too long time. Compared with traditional cement, the modern Portland cement due to the increase of cement fineness and the increase of the content of c3s strength development speed obviously accelerated, but for adding mineral admixture of cement, the hydration speed is still slow.     There are discussed that can be used for less than the specific age strength of 28 d to determine the strength grade of CGM high-strength grouting material, but due to the age of 28 d use for a long time. It is difficult to receive other people judge strength grade age. Sometimes, for some reason need according to the strength of the grouting material 7 d concluded that the strength of 28 d, at this moment need 7 d strength and the strength of 28 d relationship there is a certain difference, cannot treat as the same for grouting material.     The strength development of the varieties of cement grouting speed, CGM high-strength grouting material how much money a bag of slurry water cement ratio also affects the strength development of the grouting material, low water cement ratio of grouting material strength development speed is higher than the Shanghai by80 grouting high water cement ratio of grouting material, this is because in the case of low water cement ratio, grouting material in cement around particles are of a similar performance so cement gel forming faster to point out is, compared with the low temperature condition, under the condition of high temperature in CGM high-strength grouting material strength development faster, and the intensity of 28 d and 7 d intensity ratio is lower than under the condition of low temperature strength ratio. Master the CGM high-strength grouting material strength relationship with age is very important, when grouting material structure in use need to withstand the design load, must ensure that the grouting material curing at least 28 d in order to obtain sufficient strength. For some of the condition of high early strength requirement, such as prefabricated grouting material, prestressed grouting material or premature demolition construction template, etc, must know the early strength of the grouting material, to ensure the safety of the structure.
