Different Test Methods For Workability of Self Compacting Concrete [PDF]
![Different Test Methods For Workability of Self Compacting Concrete [PDF]](https://i0.wp.com/theconstructor.org/wp-content/uploads/2020/05/SCC-629x420.jpg)
Self-compacting concrete (SCC) is a highly flowable, non-segregating concrete that fills uniformly and completely every corner of formwork by its own weight and encapsulate reinforcement without any vibration, whilst maintaining homogeneity. A concrete mix can only be classified as self-compacting ...

Standard deviation for concrete is the method to determine the reliability between the compressive strength results of a concrete batch. The standard deviation serves as the basis for control of variability in the test results of concrete for the same ...
Fire Damage Mechanism of RC Structure and Assessment Method
Fire cause concrete surface cracking and crazing, chemical decomposition, and microcracking and spalling. These impacts can significantly change the properties of structural concrete, reducing strength and durability, and altering structural behavior. Assessment and evaluation of damages caused by fire is ...
Applications and Importance of Non-destructive Tests on Concrete
Non-destructive tests (NDT) are widely used and play an important role in engineering projects including newly constructed and existing structures. For new structures, applications are mainly quality control or the resolution of doubts about the quality of materials or construction. ...
Post-Concrete Inspection and Testing: Purpose, and Applications
Post concrete inspection of concrete structures is essential to check for any damage or defects that may require repair. Immediately after stripping the formwork, all concrete members casted are carefully inspected and any defective work or small defects either removed ...
Casting and Curing Concrete Specimens in Field Based on ASTM C31
Casting and curing of concrete cylinder and beam specimens from representative samples of fresh concrete is crucial in building constructions. This is because the results of the tests conducted on these specimens are employed for many significant purposes. For instance, ...
