Pre-excavation locating reduces uncertainty; it does not certify that the ground is empty. The distinction …

Curing conditions
There are different curing conditions,depending on the property of concrete. Cured concrete strength continuously increases with the passage of time. Water that is necessary for the formation of hydration products will not evaporate and
Continue readingPlastic shrinkage
Shrinkage that occurs in freshly laid concrete and that shrinkage occurs if there are no aids to stop evaporation from freshly laid concrete. Plastic shrinkage occurs in the early stages almost within a first 10-12hours.
Continue readingShrinkage In Concrete
Shrinkage is defined as “deformation in fresh and hardened concrete that occurs due to loss of moisture”. Shrinkage is not dependent on load.
Continue readingCompressive Strength Of Concrete
It is the strength of concrete against applied compressive load or it is the strength of concrete before concrete fails to bear any load increment.
Continue readingAmount Of Water | Effect on Workability
Water amount is the most prominent factor, which affects the workability of fresh concrete. Workability is mostly the measure of flow ability of fresh concrete in between the voids and how well concrete will be …
Continue readingWorkability of Concrete
It is that property of concrete which determines how much effort will be required to properly handle a freshly mixed batch concrete with lessen loss of homogeneity.
Continue readingChemical Admixtures
Chemical admixtures are those, which are added after batching of concrete so that every separate admixture gives some important functions to the properties of concrete.
Continue readingMineral Admixtures
Mineral admixtures are those admixtures which are obtain from industries. Mostly mineral admixtures are residue of some industries and are used to replace cement and make concrete cheaper.

These are many factors which has strong influence on strength of concrete. Of these factors are not being considering during mixing then these air entraining admixtures may have some negative impact on properties of concrete.
Continue readingEffect of Air Entraining Admixtures on Concrete
Air entraining admixtures affects very widely the properties of concrete. Slump value of concrete increases by using air entraining admixtures, by using
