Optimizing The Use of Fly Ash for High Strength & Durability in Concrete

1. AN INTRODUCTION – FLY ASH Fly Ash is used as a supplementary cementitious material (SCM) in the production of Portland cement concrete. When it is used in conjunction with Portland cement. According to fly ash suppliers in Egypt, a Pozzolan is defined as aluminous material as itself possess no cementitious value, and in the presence of moisture, it chemically reacts with calcium hydroxide at ordinary temperature. By increasing the amount of concrete is not without drawbacks.

2. CLOSING THOUGHTS HOW TO OPTIMIZE FLY ASH ON PROPERTIES OF CONCRETE One of the most reasons for using fly ash in most of the concrete applications is to get durable concrete at reduced cost. Workability & consistency are both properties of concrete and they finished without segregations. To know more about one of the best fly ash suppliers in Indonesia and Class F & Class C fly ash products, please visit http://flyashsupplier.com ASTM The properties of fresh concrete & mechanical properties as well as durability of hardened concrete that are strongly influenced by incorporating fly ash into the mixture. Workability is improved & water demand is reduced for most of the fly ashes. Setting time is extended in cold weather. SPECIFICATIO NS FOR FLY ASH Class F – is normally produced from burning bituminous coal, which meets the applicable requirements. This class has pozzolanic properties. Class C – is produced from sub-bituminous coal, which meets the applicable requirements for this class. Also, it has some cementitious properties.
