1. cement glue configuration: (weight ratio) cement (425 # portland cement): 80 1 the ratio of cement to water is1:0.25: 0.5; (Volume ratio) 80 1 glue 1: water 3: cement 6. When preparing, first add water and 80 1 glue into the container and stir to melt. After adding cement, stir until there is no clot or precipitation, and then use it.
