The Setting Time of Portland Composite Cement Mixed with Calcium Stearate
This study aims to determine the effect of calcium stearate in setting time of Portland Composite Cement setting time. Tests carried out include the consistency of normal PCC, initial setting time, final setting time, mortar compressive strength and phase hydration. The calcium stearate content is used as additive for PCC is 0, 1, 2 and 3% of the weight of cement. Used cement is PCC type without added fly ash and with additional 10% fly ash by cement weight. Mortar compressive strength specimens are cubes with size of 50 × 50 × 50 mm. Mortar compressive strength test was performed at 3, 7, 14 and 28 days. The phase of hydration test object is a powder which is drilled from a harden cement paste. This powder is tested for its compound content using an X-Ray Diffraction (XRD) tool. The test results found that the use of calcium stearate accelerated the initial and final setting time of PCC around 78 min. Mortar compressive strength decreases when the use of calcium stearate in the mortar mixture increases. This tendency is in line with the results of the XRD test that the amount of Crystalline formed at 28 days becomes smaller when the amount of calcium stearate added to PCC increased.
