Fresh Concrete

If the concrete ingredients offer significant resistance against each other, the movement of the concrete is hindered, making the placement and handling …
Workability depends on factors like water content because it boosts lubrication among the concrete ingredients, aiding workability. Finer particles, for …
Excessive horizontal movement of concrete within forms, or dropping it from a considerable height or through narrow spaces with directional changes, can …
The slump test measures concrete workability and uses a 12-inch high truncated cone mold, narrowing from eight inches at the base to four inches at the …
If water from the concrete mix rises to the top of the newly laid concrete, it is bleeding. The cause is the mix's solids failing to retain all water …
The compacting factor test determines the workability of concrete with aggregate sizes up to a maximum of one and a half inches. The test equipment …
The Vebe test is conducted on concrete to identify its workability, preferably for dry mixes. The test apparatus comprises a cylindrical chamber measuring …
The flow table test, used to find the workability of concrete and evaluate highly flowable concrete, involves an apparatus consisting of a wooden board …
Fiber reinforced polymer (FRP) anchors are a promising way to enhance the performance of externally-bonded FRPs applied to existing structures, as they …
Residual stress is an essential factor to keeping the hermeticity and robustness of a glass-to-metal seal structure. The purpose of this report is to …
