INTRODUCTION Fly ash concrete is an ecofriendly construction material in which fly ash replaces a part of Portland cement But IS:456 – 2000 and ACI:318 allows replacement of OPC by Fly ash up to 35% only as binding material High volume fly ash concrete is a concrete where a replacement of about 35% or more of cement is made with the usage The specific surface Blaine of the cement was 4,050 m 2 /kg; fineness of the collected coal fly ash was 3,976 m 2 /kg The coal bottom ash was ground in a ball mill up to a Blaine fineness of 3,463 m 2 /kg, similar to that of the Portland cement (5–8% residue on 45 μm sieve) Several coal fly and ground coal bottom ashes were mixed in the laboratory using a powder mixerCoal Bottom Ash for Portland Cement Production Fly ash bricks are manufactured by mixing water, quarry dust/river sand, cement, fly ash and stone aggregates less than 6mm, normally the actual cement volume will be replaced with 10% to 20% fly ash They are considered good and inexpensive building materials including Class C, fly ash and waterFly ash Bricks: Properties, Advantages DisadvantagesAsia Cement (China) Holdings Corporation (hereinafter referred as the “Company”) was incorporated by Asia Cement Corporation, a subsidiary of Taiwanbased Far Eastern Group, in Asia Cement(China) Holdings Corporation About Us introduction of ash cement introduction of ash cement Shanghai Machine Co, Ltd is a high technology, engineering group We are specializing in the research, development, and production of stone crushers, mobile crushing plant, grinding mill and introduction of ash cement
