Initial Time of Set of Fresh Concrete
admin2022-07-02T14:48:44+03:00Initial Time of Set of Fresh Concrete - Use this method to determine the initial time-of-set of fresh retarded concrete in the field. This method describes a procedure that uses a penetration resistance apparatus and the mortar fraction of the concrete. The values given in parentheses (if provided) are not standard and...
Flow Table Test
admin2022-07-02T14:14:43+03:00Concrete Flow Table Test
Flow Table Test is also used to identify transportable moisture limit of solid bulk cargoes. It is used primarily for assessing concrete that is too fluid (workable) to be measured using the slump test, because the concrete will not retain its shape when the cone is...
Concrete Cube Testing
admin2022-07-01T16:36:31+03:00Why does concrete need to be tested?
The purpose of a concrete cube test is to ensure that the concrete meets its expected compressive strength. If the concrete doesn’t hit its design strength – or if it hasn’t been tested – the supplier can’t guarantee its quality. And if the supplier can’t guarantee...Curing of Cement Concrete
admin2022-07-01T16:44:18+03:00Curing of Cement Concrete
Curing of cement concrete is defined as the process of maintaining the moisture and temperature conditions of concrete for hydration reaction to normally so that concrete develops hardened properties over time. The main components which need to be taken care of are moisture, heat, and time...
Measurement of Air Content in Concrete
admin2022-06-28T12:52:17+03:00AIR CONTENT METER
Air content of concrete is measured by the pressure air measurement method which is based on the principles of The Boyle's law. The Boyle's law states that the volume of the gas is inversely proportional to the pressure. By the application of pressure on a concrete of known volume (that...
CONCRETE SLUMP TESTS – MEASURING THE WORKABILITY OF CONCRETE
admin2022-07-04T10:27:54+03:00Concrete slump test or slump cone test is to determine the workability or consistency of concrete mix prepared at the laboratory or the construction site during the progress of the work. Concrete slump test is carried out from batch to batch to check the uniform quality of concrete during construction. The slump test...
