Department of Civil Engineering, ABES Engineering College, Ghaziabad organized two days Guest Lecture on “Testing and Control Of Concrete Quality” on 20th June 2018 And Guest Lecture on “Pre Stress concrete Test and ultrasonic pulse velocity test Testing and Control of Concrete Quality “21 June 2018 by Dr. B. K. Singh. Professor and HOD CE, GNIOT Greater Noida.
Concrete is a composite material that consists essentially of a binding medium within which are embedded particles or fragments of
Aggregates, usually a combination of fine aggregates and coarse aggregates, Portland cement concrete, the binder is a mixture of
Portland-cement and water, with or without admixtures. In order to determine the quality of concrete on site, it shall undergo quality
Here are 6 common quality tests on concrete before and after completion of casting on site
- Slump test before leaving the batching plant and on arrival on site
- Compressive strength test
- Water Permeability test
- Rapid Chloride Ion Penetration Test
- Water Absorption Test
- Initial Surface Absorption Test
This Lecture provides students an understanding and ability to analyze and design pre-stressed concrete structural elements. Topics discussed include the concept and principles of pre-stressing, methods of pre-stressing concrete, stress limits, losses of pre-stress, selection of sections, serviceability and strength requirements. Students will also be exposed to the complete analysis and design procedure of simply supported pre-stressed concrete non-composite and composite beams, and design principles of continuous beams.
A pre-stressed concrete structure is different from a conventional reinforced concrete structure due to the application of an initial load on the structure prior to its use. The initial load or ‘prestress’ is applied to enable the structure to counteract the stresses arising during its service period.
