High speed railway special shape rigid frame bridge of self-compacting facing water - grouting material quality requirements Henan CGM high-strength non-shrinkage grouting material price

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material in henan, henan CGM high-strength non-shrinkage grouting material manufacturer, self-compacting CGM high-strength non-shrinkage grouting material facing water quality should meet the following requirements: the & # 8195;   1, CGM high-strength non-shrinkage grouting material performance meet the self-compacting CGM high-strength non-shrinkage grouting material application technology regulation level I self-compacting CGM high-strength non-shrinkage grouting material, has good flow property and segregation resistance, can satisfy the engineering characteristics ( Reinforcement content of up to 327 kg/m&sup 3; , divide up to 11 m) Demand, in the case of without mechanical vibration can fully flow and fill the template and the wrapped steel, forming internal components.       In order to ensure the CGM high-strength non-shrinkage grouting material facing water effect, a new mixed CGM high-strength non-shrinkage grouting material must be good uniformity, good cohesion, no bleeding, segregation. In order to ensure the CGM high-strength non-shrinkage grouting material pouring smoothly, CGM high-strength non-shrinkage grouting material should be kept within 2 h work basic no change in performance.     2, 56 d CGM high-strength non-shrinkage grouting material compressive strength meet the requirements of C50 strength grade; CGM high-strength non-shrinkage grouting material total alkali content is not more than 3. 0kg/m³ , the total content of C1 total gelation materials should not exceed 0. 10%; CGM high-strength non-shrinkage grouting material has good volume stability, and durability to meet the requirements in 100.     3, CGM high-strength non-shrinkage grouting material hardening after ripping, 4 m in CGM high-strength non-shrinkage grouting material surface color, without clear off color, bubbles, small and evenly by a gauge CGM high-strength non-shrinkage grouting material side how much of the law of the bolt hole, Ming sewing, cicada seaming combined CGM high-strength non-shrinkage grouting material formed by natural texture as the finishing effect.   & High strength CGM high-strength non-shrinkage grouting material manufacturers have spent         Second, the self-compacting facing water CGM high-strength non-shrinkage grouting material quality assurance technology & # 8195;   1, CGM high-strength non-shrinkage grouting material raw materials of various technical parameters should be consistent with the railway CGM high-strength non-shrinkage grouting material structure durability design the interim provisions on the requirements, and the raw materials used in the same engineering should be the same manufacturer, the same origin, the same variety, in order to guarantee the CGM high-strength non-shrinkage grouting material can satisfy the demands of 100 high durability, alkali content of all raw materials are strictly controlled and the chloride ion content. CGM high-strength non-shrinkage grouting material should have enough store capacity of raw materials, to ensure that at least the same visual space CGM high-strength non-shrinkage grouting material of the color of the raw materials and various technical parameters basically stable. Also should satisfy the requirements;     2, cement; The color of the cement to secondary grouting bottom CGM high-strength non-shrinkage grouting material material color appearance is the most direct, the influence of different manufacturer of cement is often color difference is obvious. Due to the lack of decorative water CGM high-strength non-shrinkage grouting material surface protection, are greatly influenced by the natural environment.     3, mineral admixtures; Chooses the admixture of must be harmless to reinforced steel. Consider control hydration heat, the durability of the CGM high-strength non-shrinkage grouting material, improves the performance of CGM high-strength non-shrinkage grouting material.     4, fine aggregate; Fine aggregate gradation is bad, silt and clay pieces of content is too large, easily lead to CGM high-strength non-shrinkage grouting material exudation, water reducing agent dosage, high water consumption, high CGM high-strength non-shrinkage grouting material and poor mechanical properties and durability of adverse effects, and can also lead to CGM high-strength non-shrinkage grouting material apparent uneven colors after hardening.
