Hardened Concrete - an overview | ScienceDirect Topics

Penetrating sulphates react with hardened concrete and produce reaction products which have a volume which is greater than the available pore space (Claisse and Unsworth, 1996). In normal structures, this causes expansion of the matrix which continues until the critical stress is developed and cracks form.

Hardened Concrete: Properties of Hardened Concrete

Hardened Concrete has a tendency to become porous due to the presence of voids formed during or after placing of concrete. Penetration by the substance may adversely affect the durability, i.e. Ca(OH) 2 leach out and corrosion occurs due to lack of air and moisture.

Properties of Hardened Concrete; A Detailed Guide.

When hardened concrete is loaded, it deforms. partly as a result of elastic strain (which is recovered on the removal of the load); partly as a result of plastic strain (a permanent deformation). This latter non-elastic time dependent deformation is a typical property of concrete and is commonly referred as CREEP.

FRACTURE PROCESS ZONE AND KR-CURVE OF

The extension of the fracture process zone in mortar has been determined with a multi-cutting technique. The fracture process zone is removed step by step with a diamond saw. The corresponding compliance curve, is established with the applied load always less than the level which will induce a further damage in the material. Compared with the compliance calibration curve this provides ...
