5. Small amount of residue: The user always thinks that the horizontal type equipment has a large amount of residue, which is not the case. Because the gap between the outer ribbon and the U-shaped barrel wall ...
The generated compound CaO·Al2O3·CaSO4·32H2O is called “cementBacillus” This reaction is relatively rapid and can fix a large amount of free water in the form of crystal water, so the reduction of free water in soil is about 46% of the amount generated by cementBacillus. However, ...
Deep cement mixing piles are a key technology for treating settlement distress of soft soil subgrade. However, it is very challenging to accurately evaluate the quality of pile construction due to the limitations of pile material, large number of piles and small pile spacing. Here, we propose th...
