Application Of Ground Lime Powder In Mixed Soil

Around grinding fine powder (100 mesh) instead of fly ash, in high, medium and low strength grade of concrete in its performance has a certain degree of ascension, especially high strength grade of concrete, due to the higher total gelation materials, using fly ash as its viscosity is bigger, extension degree is relatively low, collapsed slump tube for a long time, but in the use of grinding fine powder, The situation of high viscosity is greatly improved, and the flow performance of concrete becomes more ideal. 

According to the analysis, water than fly ash of fine powder grinding, fine grinding powder had water reducing effect, so the unadjusted concrete water consumption under the premise of the workability of concrete must be improved, roundness higher powder also play a role of micro ball, reduce the friction between the sand and gravel, which improved the workability of concrete.
