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...

CATHODIC PROTECTION OF STEEL REINFORCED CONCRETE BY CONDUCTIVE EPOXY PAINTS IN MARINE ENVIRONMENTS

Anodes are critical component of cathodic protection systems. As part of this effort, three different anodes were tested in a cathodic protection system that was designed and constructed to prevent further corrosion of reinforced concrete. This anodic system includes an electrically conductive coating composition applied in fluid form over an outer surface of the concrete mix. The composition f...

Binary Effect of Fly Ash and Palm Oil Fuel Ash on Heat of Hydration Aerated Concrete

The binary effect of pulverized fuel ash (PFA) and palm oil fuel ash (POFA) on heat of hydration of aerated concrete was studied. Three aerated concrete mixes were prepared, namely, concrete containing 100% ordinary Portland cement (control sample or Type I), binary concrete made from 50% POFA (Type II), and ternary concrete containing 30% POFA and 20% PFA (Type III). It is found that the tempe...

Effect of High-Carbon Fly Ash on the Electrical Resistivity of Fly Ash Concrete Containing Carbon Fibers

Two series, each consisting of seven high-volume fly ash concrete mixtures with conductive carbon fibers, were used in this investigation. The first series of the concrete mixtures contained ASTM Class C fly ash and 0, 1, 3, 5, 7.5, 10, and 20 lbs. carbon fibers per cubic yard of concrete. The second series of concrete mixtures contained high-carbon fly ash in addition to the materials used in ...
