Effect of Biomass Fly Ash on Fresh and Hardened Properties of High Volume Fly Ash Mortars

نویسندگان

چکیده

The objective of this work was to assess the use biomass fly ash (BFA) as cement replacement material or an alkalinity source in high volume mortar and concrete. Mortar formulations were prepared with different types replacement: from thermal power plants, BFA, a blend two pozzolans, small amounts BFA or/and hydrated lime (HL). tested both fresh hardened state. by ashes led decrease mechanical strength. best strength values obtained when higher HL content introduced mortars, however, mortars lower presented results for majority tests. In general, has similar effect on cementitious coal ash, having good performance replacement.

Thermal Properties of High-Volume Fly Ash Mortars and Concretes

As sustainability moves to the forefront of construction, the utilization of high volume fly ash concrete mixtures to reduce CO2 emissions and cement consumption per unit volume of concrete placed is receiving renewed interest. Concrete mixtures in which the fly ash replaces 50 % or more of the portland cement are both economically and technically viable. This paper focuses on a characterizatio...

Acid Resistance of Fly ash based Geopolymer mortars

Geopolymers are a new promising binder manufactured by activation of a solid aluminosilicate source material with a highly alkaline activating solution and aided by heat. Fly ash, considered to be a waste material is rich in silica and alumina and hence can be used as a source material for manufacture of Geopolymers. These binders have been reported to achieve high early strength and better dur...

Rheology and setting of high volume fly ash mixtures

While high volume fly ash (HVFA) concretes can be designed and produced to meet 28-d strength requirements and often even exceed the durability performance of conventional concretes, a persistent problem is the potentially long delay in setting time that produces concurrently long delays in finishing the concrete in the field. Previous isothermal calorimetry studies on two different powder addi...

Effect of Fly ASH on Properties of Concrete

This paper presents an Effect of Fly Ash on Properties of Concrete. In the present study. Use of fly ash in concrete imparts several environmental benefits and thus it is ecofriendly. It saves the cement requirement for the same strength thus saving of raw materials such as limestone, coal etc required for manufacture of cement. Fly ash is pozzolanic material & it improving the properties of co...
