Coarse Aggregates

This study focusses on the development of fly ash concrete made with water/cement ratio of 0.5.To develop fly ash concrete in this study, 40% of cement is replaced with fly ash, manufactured sand is used as fine aggregate, light weight fly ash aggregate as used coarse aggregate and for mixing concrete instead of tap water 12% lime concentrated water is used. The fly ash concrete compressive strength obtained is equivalent to that of M30 grade concrete made with OPC. Two sets of samples are prepared one set with 40% fly ash concrete made with river sand and natural crushed stone coarse aggregates and another set of sample with 40% fly ash concrete made with manufactured sand and artificial light weight fly ash coarse aggregates. Experimental studies revealed that use of manufactured sand enhanced compressive, tensile and flexural strengths by 6-8% only. Even permeation properties such as water absorbtion and porosity of fly ash concrete made with manufactured sand and artificial light weight fly ash coarse aggregates is almost similar to that of fly ash concrete made with made with river sand and natural crushed stone coarse aggregates. The results conclude that fly ash coarse aggregates can be used for structural applications instead of natural coarse aggregates but not feasible for use in pavement as per IS 2386. Manufactured sand can be used as 100% replacement to river sand in fly ash based concretes with improved properties of concrete

By Products

The disposal problem of industrial by-products like fly ash, heavy metal sludge, sewage sludge etc. are increasing day by day. To use by-products in large volume the applications like embankment fill or aggregate replacement material should be considered for sustainable development. This study is focused on properties of artificial light weight aggregate on concrete and the effect of cold bonded light weight aggregate on concrete through partial and complete replacement of coarse aggregates. Artificial Lightweight aggregate can be produced by nodulizing the by-product for example fly ash in a pelletizer with a proportionate quantity of water, cement and further hardened by cold bonding or sintering. Due to the impact of earth quake forces all over the world, the need for light weight structural design is increasing presently, as it reduces mass of the structure. The concrete produced is light weight in nature and has added the benefit of reducing overall cost, especially in transportation and placing etc. it has its own advantages like reduced dead load, and thus economic structures, high sound absorption and good fire resistance. Keywords—Artificial light weight aggregate, cold bonding, Fly ash, Fly ash aggregate, Pelletization, and Sintering.

Al Matrix

The paper illustrates Carbon nanotubes reinforced pure Al (CNT/Al) composites and fly ash reinforced pure Al (FA/Al) composites produced by ball-milling and sintering. Microstructures of the fabricated composite were examined and the mechanical properties of the composites were tested and analysed. It was indicated that the CNTs and fly ash were uniformly dispersed into the Al matrix as ball-milling time increased with increase in hardness.
