Low Heat Portland Cement (IS: 12600)

• Lower contents of the more hydrating compounds, C3S and C3A and more contents 

of C2S.

• Desirable in mass concreting of gravity dam.

• Possesses less compressive strength having initial setting time is about 1-hour final 

setting time is about 10 hours.

• 272 and 314 k/J/kg at the end of 7 and 28 days.

• 10mm and 0.8%.

Portland Pozzolana Cement (IS: 1489 Part I)

• Portland cement clinker and pozzolana (usually fly ash 10 to 30% by mass of PPC.

• The average compressive strength of mortar cube, (area of face 50 cm2

) composed 

of 1:3 by mass and (𝑃/4+ 3)%.

• Initial time = 30 minute and final setting time= 600 minute.

• Drying shrinkage should not be more than 0.15%.

• Fineness should not be less than 300 m2

/kg.

• Is used in the paces of mass concrete such as dams.

Quick Setting Portland Cement

• Ground much finer than OPC.

• Sets quickly but does not harden quickly.

• Initial setting time = 5 minutes.

• Final setting time = 30 minutes.

• When concrete is to be laid under water or in running water.

Masonry Cement (IS: 3466)

• Portland cement clinker is ground and mixed intimately with pozzolanic material or 

non-pozzolanic waste materials gypsum and air entraining plasticizer,

• Good workability reduces shrinkage and water retentivity.

• Used for masonry works, plaster work.

• Not be used for concrete work.

• Physical requirements of masonry cement are as follows:

1. Fineness: Residue on 45-micron (15)

a) Initial, Min (90min)

b) Final, Max (10mm)

3. Soundness:

a) Le-Chatelier expansion, Max (90mm)

b) Autoclave expansion, Max (1 per cent)

4. Compressive Strength
