Green Concrete with HighVolume Fly Ash and Slag with

PDF Green Concrete: A Literature Review - IJERT

green concrete manufactured from some industrial wastes such as fly ash, silica fume, slag modified, glass modified, rubber modified and recycled aggregate concrete. combination of high volume fly ash (HVFA) and slag. Four different mixtures with various contents of HVFA and slag were prepared. After the mixes were prepared, specimens

Use of fly ash as fill for low lying areas. High volume (about 12Mt/year), low value use. Accounts for about 10% of fly ash use in India. Contact of fly ash with groundwater is primary concern due to potential of leaching of trace elements. Market for this use has stabilized and future increases will be incremental

Cementless fly ash binder makes concrete 'green

Manufacturers often use a small amount of silicon- and aluminum-rich fly ash as a supplement to Portland cement in concrete. "The industry typically mixes 5 to 20 percent fly ash

Mechanical Properties of Silica Fume Modified High-Volume

The existing form of self-compacting concrete (SCC) comprises of a large amount of powdered and fine materials. In this study, a part of the cementitious material was replaced with constant high-volume fly ash, and a portion of fine aggregates was substituted by crumb rubber (CR). Besides that, silica fume (SF) was added, with the hope that by implementing a new type of nanomaterial, the loss

PDF Experimental Study on Bond Strength and Flexural Strength

Fly ash, is a coal combustion product. In arrears to its pozzolanic properties, fly ash is used as a replacement for Portland cement in concrete. Coarse aggregate is partially replaced by recycled aggregate at optimum percentage of replacement. The utilization of fly ash for cement, copper slag for fine

Winter Weather and Using Fly Ash - The Portland Cement

Fly ash concrete is more likely to provide satisfactory scaling performance if the water-cementitious materials ratio does not exceed 0.45 and the level of fly ash does not exceed about 25 percent. This, of course, assumes an adequate air-void system is present in the concrete and that proper construction practices are adhered to.

Influence of nano silica on compressive strength

This study investigated the influence of nano silica (NS) addition on the early‐ and later‐age compressive strengths and durability properties such as sorptivity, drying shrinkage, volume of permeable voids, and rapid chloride permeability, along with microstructural changes, of high‐volume slag (HVS) and high‐volume slag-fly ash (HVS‐FA) blended concrete.

Eco-Friendly Alternatives To Traditional Concrete

Fly Ash is mixed with lime and water to make it strong and durable, similar to conventional cement. Use of fly ash in Ashcrete makes it an environment friendly alternative, since it can replace cement which in turn leads to reduced CO2 emissions. Moreover, 25% of cement can be replaced using high-volume fly ash concrete.
