Fly ash is used in about 50% of ready mixed concrete (PCA 2000). Class F fly ash is often used at dosages of 15% to 25% by mass of cementitious material and Class C fly ash is used at dosages of 15% to 40% by mass of cementi-tious material. Dosage varies with the reactivity of the ash and the desired effects on the concrete (Helmuth 1987 and

Substituting fly ash microbeads for silica fume can significantly reduce the cost and improve performance of high-performance concrete, with significant benefits. The particles of fly ash are very small, which can act as a micro-aggregate in concrete and fill the tiny pores. At the same time, the surface hydrates to form a gel.

Conditioned fly ash is also available in ash mound for use in land fills and ash building products. Fly ash micronisation, for the obtainment of a material entirely smaller than 10 microns, can be operated by grinding it or by its aerodynamic classification.

Fly is a by product of coal based thermal power station generated by the combustion of pulverized coal. Fly Ash is a fine, grey amorphous powder, rich in silica & alumina and spherical in shape. The properties of Fly Ash may vary widely, both physically and chemically, depending upon the nature of coal, the efficiency of coal combustion process ...

Published on : 31 Aug, 2020, 6:30 pm. Dirk India Pvt Ltd (Unit of Ambuja Cement Limited) is in the business of classification of fly ash and manufacturing PPC by the method of intermixing. Fly ash is being classified by centrifugal cyclone separators to various micron size constitutes to different grades of fly ash known as Pozzocrete.

Method for treatment of fly ash for preparation of mortars and concretes.

A Micron-Master Jet Pulverizer jet mill (0.61 m in diameter)was used in this study to grind the materials as shown in Fig. 1a and b. The materials to be ground were blended for 60 min in a 0.19 m 2 V-blender (this step is only conducted for blends). After blending, approximately 45 kg of the pre-blended material was transferred into the hopper for jet mill grinding.
