High-volume fly ash concrete

Table 7.19 Typical mechanical properties of high-volume fly ash concrete made with ASTM Type I and Type III cements (Maihotra [69]) ...

High dosages of a superplasticizer permit the replacement of a large amount of the cement by fly ash, while maintaining workability and strength. This is typical high-volume fly ash concrete. 

Giaccio and Malhotra [143] introduced the term high-volume fly ash concrete in 1980, however, F or C class fly ash should replace at least 50 % of cement and the...

High-volume fly ash concrete is characterized by a high fly ash content and a reduced amount of Portland cement in the mix. The cement/ash replacement ratio is high, and may exceed 50%. Typically, high-volume fly ash concrete mixes contain 100-200 kg/m of cement and 150-300 kg/m of fly ash. 

The use of high-volume fly ash concrete may be recommended in applications where the requirements for strength are low and where the release of very little heat of hydration is essential. It is unsuitable for steel-rein-forced eonerete constmctions, owing to the insufficient protection of the steel from conosiom...

In Part Four, Chapter 11 offers the effectiveness of calcium carbonate nanoparticles on the improvements of compressive strength and durabUity of high-volume fly ash concrete. These resulting properties are further correlated with relevant microstructure and crystalline phases by means of X-ray diffraction, mercury intrusion porosimetry, differential thermal analysis, and thermal gravimetric analysis. Chapter 12 reviews current research and relevant techniques for the manufacture and application of amorphous carbon and its nanocomposites. Various applications for the textile, plastic, and healthcare industries, as well as in the fields of gas and water filtering, electrical apphcations, and food packaging, are also discussed based on the superior and unique propoties of...
