High Fly Ash Concrete

High filler concrete using fly ash Chloride

Most high filler concrete studies are based on relatively high contents of powder cement filler >400 kg m 3 This paper aims to increase the total fly ash content relative to the clinker content while simultaneously minimizing the total powder content in the concrete to values lower than 300 kg m 3 The motivation for decreasing the total powder content using fly ash as a cement
