Effect of Fly Ash on Durability of Concrete

Durability Studies On Concrete With Fly Ash & Ggbs

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Durability of concrete is defined as its ability to resist weathering action, chemical attack, abrasion or any other process of detoriation. It also includes the effects of quality and serviceability of concrete when exposed to sulphate and chloride attacks. Fly ash and Ground Granulated Burnt Slag (GGBS) are chosen


Fly ash concrete is extensively used among various industries. Use of such concrete is increasing because of higher performance, environment friendly and conserves natural resources. By adding admixture to concrete makes the concrete mix workable with lower water cement ratio and improves the strength of concrete. 1.2. Fly Ash

Effects of Curing and Test Conditions on the Salt Scaling

Some specifications currently limit the amount of fly ash used in concrete exposed to de-icer salts and freezing conditions because of concerns over salt scaling durability. There is concern that the standard test method commonly used to assess concrete salt scaling performance, ASTM C672, is overly severe and not representative of field

On effects of fly ash as a partial replacement of cement

For this purpose, systematic experiments have been carried out to investigate the influences of fly ash ratio and age. The compressive strength of concrete specimens with replacement ratios of 15%, 30% and 45%, and aged 7 and 28 days are measured and are compared with those of the concrete specimens without fly ash at the same ages.

Effect of High Loss on Ignition-Fly Ash on Properties of

In addition, the concrete mixtures with 10% and 20% fly ash content showed the higher compressive strength, especially at long-term ages, than that of the fly ash-free concrete mixture. Further, all of the fly ash concrete mixtures exhibited the good quality with ultrasonic pulse velocity values of higher than 4100 m/s.

Comparison of High Performance Fly Ash Concrete Using Nano

The effect of various silica fumes contents such as 1%, 2% & 3% (wt. %) as partial replacement of cement on the compressive strength of cements is evaluated in the first part. The nano silica fume content which exhibits the highest compressive strength above is used in high volume fly ash concretes containing 30% and 50% class F fly ash.

PDF Evaluation of Fly Ash in Bridge Deck Concrete

fly ash in concrete is desirable for economic and environmental reasons. If the use of fly ash in bridge deck concrete is allowed, the contractor could elect to use a modified D-57 mix with or without admixtures and reduce the ce­ ment content by using fly ash and Class III durability aggregates. Therefore,

The effect of fly ash properties on concrete strength

The recognition that fly ash frequently exhibits pozzolanic properties has led to its use as a constituent of concrete. In South Africa the carbon content (as measured by loss on ignition, LOI) and the particle size of classified ash is limited to 5 % LOI and less than 12, 5 % larger than 45 (m respectively.

Experimental Study on Durability Improvement of Fly Ash

Jun 09,  · The effects of durability improving admixture, air content, water-binder ratio, and fly ash replacement ratio on the performance of fly ash concrete are discussed in this paper. The results show that by using durability improving admixture in nonair-entraining fly ash concrete, the compressive strength of fly ash concrete can be improved by 10%
