Strength and behaviour of Fly Ash based Steel Fibre Reinforced Concrete Composite
This experimental investigation is to study the effects of replacement of cement (by weight) with five percentage of fly ash and the effects of addition of steel fiber composite. A control mixture of proportions 1:1:49:1.79 with w/c of 0.45 was designed. Cement was replaced with five percentages (10%, 15%, 20%, 25% & 30%) of Class C fly ash. Four percentages of steel fibers (0.15%, 0.30%, 0.45%...
متن کاملALKALI Activated FLY-ASH Based Geopolymer Concrete
Considering the increasing demand for developing alternative construction materials, due to the growing environmental concerns, this paper discusses the feasibility of alkali activated geo-polymer concrete, as a future construction material. The main objective of this study involves observation of structural behaviours of the fresh fly ash-based geo-polymer concrete, understanding the basic mix...
متن کاملFly Ash-Based Geopolymer Mortar Incorporating Bottom Ash
This paper presents the results of study on effect of various parameters on mechanical properties of fly ash-based geopolymer mortar with bottom ash as partial or full replacement for sand. Compressive strength of samples with 10% bottom ash (BA) was comparable to those with only sand. Further increase in bottom ash content decreased the compressive strength. However, the reverse tendency occur...
متن کاملA Comprehensive Study of the Polypropylene Fiber Reinforced Fly Ash Based Geopolymer
As a cementitious material, geopolymers show a high quasi-brittle behavior and a relatively low fracture energy. To overcome such a weakness, incorporation of fibers to a brittle matrix is a well-known technique to enhance the flexural properties. This study comprehensively evaluates the short and long term impacts of different volume percentages of polypropylene fiber (PPF) reinforcement on fl...
متن کاملIn Situ Elevated Temperature Testing of Fly Ash Based Geopolymer Composites
In situ elevated temperature investigations using fly ash based geopolymers filled with alumina aggregate were undertaken. Compressive strength and short term creep tests were carried out to determine the onset temperature of viscous flow. Fire testing using the standard cellulose curve was performed. Applying a load to the specimen as the temperature increased reduced the temperature at which ...
