Destructive and Non-Destructive Field Testing of Concrete
Field testing of concrete structures include non-destructive testing and destructive testing. These methods are used in completing the field condition survey.
Non-Destructive Tests on Concrete – Methods, Uses
Although there can be no direct measurement of the strength properties of structural concrete for the simple reason that strength determination involves destructive stresses, several non- destructive methods of assessment have been developed. These depend on the fact that certain ...
Concrete Cube and Cylinder Test Results Acceptance Criteria
Acceptance of Concrete Test Results As per ACI-5.6 (2008) it is recommended to perform the test on concrete in fresh, hardened or old state by well qualified field-testing technicians. The respective technicians are supposed to collect and prepare the test ...
Tests for Workability of Concrete at Construction Site and Recommended Values
Various tests for workability of concrete at construction sites i.e slump test, Vee-bee test, Compaction factor test and its recommended values are given.
What are Different Tests for Concrete Quality Check?
Quality tests on concrete are performed as a part of quality control of concrete structures. Different quality tests on concrete such as compressive strength tests, slump tests, permeability tests etc.are used to assure the quality of the concrete that is supplied ...
Permeability Test for Concrete Cover to Reinforcement
The durability of concrete structures depends on the permeability of reinforcement cover by concrete. It is this thin layer of concrete over reinforcement on which life of a structure depends. The permeability tester for concrete cover is a non-destructive instrument ...
Permeability Test on Concrete Structures
When concrete is permeable it can cause corrosion in reinforcement in presence of oxygen, moisture, CO2, SO3- and Cl– etc. This formation of rust due to corrosion becomes nearly 6 times the volume of steel oxide layer, due to which ...
