Performance Test :

(a) Compressive Strength :
(i)    Prepare a Slurry by mixing API Class `G' Cement and 44% Water by weight of the Cement and determine its compressive strength after 24 hours curing at 35°C and 5500 kPa.
Record the Compressive Strength of the neat cement.

(ii)    Prepare a Slurry using 50:50 blend (by volume) of Fly Ash / API Class `G' Cement and 44% Water by weight of blend. Determine the compressive strength of the blend after 24 hours curing at 35°C and 5500 kPa. 
Compressive Strength of the blended cement shall not be less than 30% of the value obtained with neat cement 8(a)(i).

(b) Thickening Time :
(i)    Prepare a Slurry of by mixing API Class `G' Cement and 44% Water by weight of the Cement and determine the thickening time of the Slurry, as per Test Procedure in API Specification.
Record the Thickening Time of the neat cement slurry.

(ii)    Prepare a Slurry using 50:50 blend (by volume) of Fly Ash / API Class `G' Cement and 44% Water by weight of blend and determine its thickening time, as per Test Procedure in API Specification.
Thickening Time of the blended slurry shall be between 1.25 and 2.5 times the value obtained for the neat cement slurry 8(b)(i).
Note: Detailed specifications are available on request.
