Investigation into low density fly ash aggregate in micro

This paper presents the effect of low density aggregate (LDA) made from fly ash on compressive strength, flexure strength, flexure bond strength, drying shrinkage and shrinkage due to raised temperature for accelerated drying of the micro concrete for concrete repair. Sintered fly ash lightweight aggregate were crushed to required sizes and replaced by weight partially to fully; 50, 60, 70 and

Performance of Light Weight Concrete using Fly Ash Pellets

of curing, when the experimental study on cold bonded fly ash aggregates with number of days of curing period is increased [5]. In conventional concrete, weight of concrete is one of the parameters to compare with weight of fly ash aggregate concrete. Normally density of concrete is in the order of 2200 to 2600 kg/m3. This heavy self weight

Modified Bolomey equation for strengths of lightweight

Apr 04,  · Strengths of lightweight concretes containing fly ash aggregates (FAAs) are influenced both by cement–water ratio and the properties of the aggregates. It is generally very difficult explicitly to determine the properties of lightweight aggregates (such as FAAs).
