Testing Equipments #5223023

For assessing the possible rate of corrosion in reinforcing bars. The time at which corrosion of steel may commence and the rate at which it may proceed is dependent upon properties of the cement paste and the permeability of the concrete. Since the electrical conductivity of concrete is an electrolytic process, which takes place by ionic movement in the aqueous pore solution of the cement matrix, it follows that a highly permeable concrete will have a high conductivity and low electrical resistance.

Determination of the soil bearing capacity and compaction quality of soils and subbases giving immidiate evaluation of each measurement on site in just 3 minutes per measurement point.

Determination of liquid limit with penetrometer travel 40mm fitted with dropping device, automatic free-falling for a period of 5 secs.

Measurement of soil and rock movement including settlement and heave in foundations and embankments, subsidence, movement of natural and cut slopes, quarry and mining excavations, relaxation of rock around tunnels and other underground openings, radial movements and convergence of tunnels, shafts, linings and caverns, deformation of excavations in underground power houses, caverns and adits, displacements of retailing walls, cuttings, bridge piers, arches and abutments, lateral strains and settlement, foundation movements and subsidence, slope and excavation control, joint and fault displacement provides profile of extension if chained in series.

Used for rapid in-situ measurement of the structural properties of the existing road pavement constructed with unbound materials. A typical tests take only a few minutes, providing a very efficient method of obtaining information which would otherwise require the excavation of test pits.
