TESTING REPORT OF SETTING RATE FOR CALCIUM CARBIDE

Sample size:25-50mm

 

Testing process:

 

(1)Take the calcium carbide sample,size:25-50mm,crushed to size 3-5mm

(2)Put 137gram of them into 1000ml measuring cylinder,and put the water to 600ml slowly

(3)Continue to put water to 1000ml and uniform mixing after reaction completely,and then static,wait for the result.it will take 4 hours for whole process.

 

The result are as follows:

(1) Drop to 405ml after 20 min

(2) Drop to 360ml after 1 hour

(3) Drop to 358ml after 2 hours

(4) Drop to 358ml after 3 hours

(5) Drop to 355ml after 4 hours
