1. Physical Properties of Cement

1.1. Fineness of Cement

Sieve Test ( IS 4031, Part 1 1996)

• Take 100 gram weight of sample of cement and take it on the standard sieve number 9 (90 micron sieve)
• Break down the air lumps which are present in the cement sample.
• Sieve the cement sample continuously for 15 minutes.
• After that there will be some residue will remain on this you take the weight of that residue of the cement.

According to the Indian standard

Setting Properties of Cement

Mechanical Properties of Cement

• Density - ρ : 2240 - 2400 kg/m3 (140 - 150 lb/ft3)
• Compressive strength : 20 - 40 MPa (3000 - 6000 psi)
• Flexural strength : 3 - 5 MPa (400 - 700 psi)
• Tensile strength - σ : 2 - 5 MPa (300 - 700 psi)
• Modulus of elasticity - E : 14 - 41 GPa (2 - 6 x 106 psi)

Characteristics of Cement

• Provides strength to masonry.
• Stiffens or hardens early.
• Possesses good plasticity.
• An excellent building material.
• Easily workable.
• Good moisture-resistant.

Properties of Concrete

• Mechanical strength, in particular compressive strength. The strength of normal concrete varies between 25 and 40 MPa.
• Durability.
• Porosity and density.
• Fire resistance.
• Thermal and acoustic insulation properties.
• Impact resistance.

Properties of Polymer Concrete

• The binder is more expensive than cement.
• Significantly greater tensile strength than unreinforced Portland concrete (since polymer plastic is 'stickier' than cement and has reasonable tensile strength)
• Similar or greater compressive strength to Portland concrete.
• Faster curing.
