Grouting material manufacturer's choice of four elements of proportion of concrete grouting material - How much money in shijiazhuang grouting material

High strength grouting material grouting material manufacturers CGM high-strength non-shrinkage grouting material manufacturer a water/cement ratio, grouting material manufacturer for there is a requirement for the durability of concrete grouting material, according to the structure design and construction are given 'concrete grouting materials technical requirements of the low strength grade, according to the reliability 95% sure mixture strength; At a water/cement ratio as the primary water cement ratio, and in turn reduce the 0. 05% ~ 0. 1%, 3 ~ 5 water-binder title match, it is concluded that water/cement ratio and strength of the linear relationship, find out the strength of the above preparation needed water/cement ratio, to try again. Or no admixture of ordinary concrete grouting material strength - Water cement ratio relationship to select a benchmark water-cement ratio, mixed with fly ash and then adjusted by plasma such as bone than water/cement ratio. Generally, there is a requirement for the durability of medium strength grade of concrete grouting material, mixed with fly ash exceeds 30% ( Including cement containing a mixture of material) , water-binder ratio should be less than 0. 44. Second, the different grade concrete grouting grouting material manufacturer larger pulp slurry level than strength bone percentage ( Plasma bone volume Water/( kg/m³ ） 网C30 ~ ( Excluding C50) ≤0. 32 ( 1:2) ≤175 c50 ~ C60 ( Including the C60) ≤0. 35 ( 1-1. 86). More than 160 c60 (or less Excluding C60) ≤0. 38 ( 1-1. 63). Wuhan 145 three or less, the grouting material factory ShaShiHua sand ratio in the mixture, usually with a certain ratio (bone Total or aggregate) The sand ratio under the said. For grading is good stones, the choice of the sandstone in Shi Zisong heap of void ratio and sand product of loose pile of void fraction is 0. 16 ~ 0. It is advisable to 2. Generally, pumping concrete grouting material sand ratio should not be less than 36%, and should not be greater than 45%. Therefore should pay attention to the grading of the stone, the size distribution of the two or three with different particle size distribution with loose pile after it is advisable to void ratio is not more than 42%. Shi Zisong heap of void fraction is smaller, sand the smaller than can be. In water/cement ratio and the bone than the given conditions, sand ratio change can affect the main construction and the characteristics of the deformation, strength of hardened will also have an effect. Four mineral admixture, the grouting material manufacturer with high content mineral admixtures is dosage should be depending on the nature, the environment and the engineering construction epoxy grouting material wholesale conditions choose reinforcement grouting material technology is introduced. Completely in underground and underwater for engineering, especially in large volume concrete grouting material, such as the foundation slab, occlusal pile or continuous casting of underground continuous wall, bridge pile foundation in seawater, the tunnel bottom or side of the surface treatment as well as all the year round in a dry environment.
