Vibrating Machine : EI08 Used for preparing mortar cubes for the determination of compression strength of ordinary and rapid hardened Portland cement, low heat Portland cement, Portland blast furnace cement and high alumina cements.

Soil Cone Penetrometer: EI 50 For determining the liquid limit of soils.

Linear Shrinkage Mould : EI 49 - A simple mould which is filled with the soil under test.

Shrinkage Limit Set: EI 48 Shrinkage limit is the maximum water content at which a reduction in water content does not cause an appreciable reduction in volume of the Soil Mass.

Plastic Limit Test:EI 47 Moisture contents at which soil has smallest plasticity is called limit.

Air Entrainment Meter :EI 25 As entrainment of air in limited percentage improves durability of concrete and very low percentages deteriorate it ,measurement of air entrapped in freshly mixed concrete becomes important.
