Lime, sand and Portland cement make modern stucco.
Lime, sand , sometimes Portland cement, and water.
ASTM C114 is a good reference for determining free lime
The various types of ordinary portland cement are,Ordinary portland cement 33 gradeOrdinary portland cement 43 gradeOrdinary portland cement 53 grade
According to the Portland Cement Association, portland cement should not be capitalized.
OPC is ordinary Portland cement and PPC is Portland pozolona cement. OPC is obtained by grinding clinker and gypsum whereas PPC is obtained by grinding clinker gypsum and high reactive silica. High reactive silica improves the quality of cement by reducing liberated lime.
Free lime in cement refers to unhydrated particles of calcium oxide present in the cement paste. It can negatively impact the strength and durability of the concrete mixture by leading to expansion, cracking, and reduced long-term performance. To ensure good quality concrete, free lime content should be minimized during the manufacturing process.
Portland cement is made of,CaoSiO2Al2O3Fe2O3MgOAlkaliesSO3
Ordinary Portland cement is suitable. As per IRC 21, Portland Pozzolana Cement is limited for Plain Concrete only.
