STRENGTH CHARACTERISTICS OF FLY ASH CONCRETE WITH SAME WORKABILITY

Compressive Strength and Workability Characteristics of Low-Calcium Fly ash-based Self-Compacting Geopolymer Concrete

Due to growing environmental concerns of the cement industry, alternative cement technologies have become an area of increasing interest. It is now believed that new binders are indispensable for enhanced environmental and durability performance. Self-compacting Geopolymer concrete is an innovative method and improved way of concreting operation that does not require vibration for placing it an...

PROPERTIES OF ALKALI-ACTIVATED FLY ASH CONCRETE BLENDED WITH SLAG

Influence of High Temperatures on Flexural Strength of Foamed Concrete Containing Fly Ash and Polypropylene Fiber

In this study, the elevated temperature flexural strengths of lightweight foamed concrete (LFC) containing fly ash (FA) and polypropylene fiber (PF) was investigated experimentally and statistically. The variables included were the temperature degrees (in a range of 20 to 600°C), LFC densities of 600, 800, 1000, 1200 and 1400 kg/m3 and additive content. Two mixes were made by replacing 15% and ...

Strength Characteristics of Glass Fibre on Bottom Ash Based Concrete

Abstract: Bottom ash is a hazardous by-product from coal based thermal power plants. In this study fine aggregate in concrete mix has been replaced with bottom ash and glass fibre is additionally used to enhance the strength characteristics of concrete. The concrete mix design is done for M30 grade concrete. The mix is prepared for different combinations of 0%, 30%, 40%, 50% and 100% of replace...

Shear Strength Characteristics of Fiber Reinforced Fly Ash

Disposal of an industrial waste like flyash produced from burning of coals in thermal power stations requires a large land area. The decreasing availability of good construction site has led to the increased use of low lying areas filled up with industrial wastes whose bearing capacity is low. In-situ treatment of such industrial waste fills; in order to improve their bearing capacity with rein...
