10 Properties of Concrete and their Uses - theconstructororg
Concrete is known by its grade which is designated as M15, M20 etc in which letter M refers to concrete mix and number 15, 20 denotes the specified compressive strength (f ck) of 150mm cube at 28 days, expressed in N/mm 2 Thus, concrete is known by its compressive strength M20 and M25 are the .
Additional samples may be field cured (non-standard) for the purpose of early 'stripping' strengths, that is, form removal, evaluation of curing, etc but the standard cured cylinders comprise acceptance criteria Concrete tests can measure the "plastic" (unhydrated) properties of concrete ,

Dielectric properties of concrete and their influence on ,
Dielectric properties of concrete may therefore be affected not only by the moisture level at the time of testing but also by whether the concrete has previously been allowed to dry In addition concrete may have honeycombing due to poor compaction or may have areas of high salt concentrations
Experimental Study on Electrical Properties of Steel-fibre ,
In this case, mechanical properties (tensile strength) need to be improved without an accompanying decrease of the electrical resistivity In this paper, reference concrete together with three types of steel-fibre reinforced concrete (05% vol, 1% vol, 2% vol) were prepared and analyzed in terms of determination of electric properti
