Effect of Aggregates On Strength Of Concrete

On March 16, 2012 By Jalal Afsar In Concrete Strength

Aggregates gradation also have an influence on the compressive strength of concrete. Concrete strength increases when using dense gradation and increasing fines modulus of aggregates. By increasing fines modulus surface area of aggregates goes on …

Curing conditions

On March 15, 2012 By Jalal Afsar In Concrete Strength

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

Plastic shrinkage

On March 15, 2012 By Jalal Afsar In 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.

Shrinkage In Concrete

On March 15, 2012 By Jalal Afsar In Shrinkage

Shrinkage is defined as “deformation in fresh and hardened concrete that occurs due to loss of moisture”. Shrinkage is not dependent on load.

Compressive Strength Of Concrete

On March 15, 2012 By Jalal Afsar In Concrete Strength

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.

Amount Of Water | Effect on Workability

On March 15, 2012 By Jalal Afsar In 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 …

Workability of Concrete

On March 14, 2012 By Jalal Afsar In Workability

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.

Chemical Admixtures

On March 14, 2012 By Jalal Afsar In 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.

Mineral Admixtures

On March 13, 2012 By Jalal Afsar In 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.

Factors Affecting Air Entraining Admixtures

On March 13, 2012 By Jalal Afsar In Admixtures

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.
