09/05/2015 ABSTRACT This research work was experimentally carried out to investigate the effects of partially replacing ordinary Portland cement (OPC) with our local additive Rice Husk Ash (RHA) which is known to be super pozzolanic in concrete at optimum replacement percentage. With this research work, the problem of waste management of this agro-waste will be solved. The compressive strength value at 7,14,21 and 28 days is found to be 20.27, 28.34 ,33.67,37.60N/mm2 at the replacement

Recycling of Coal Ash in Concrete as a Partial

di erent fineness was used as a partial cement replacement of 0% to 30% the weight of cement. It was noticed that workability was decreased due to an increased amount of ground CBA, because it absorbed more water in the concrete mix. The growth in the compressive and tensile strength of concrete with ground CBA was not significant at the early ages. At 28 days, a targeted compressive

Fly ash is an inexpensive (FA), silica fume (SF), ground blast-furnace slag (GGBS) and replacement for Portland cement used in concrete, while it metakaolin (MK) are commonly used as a partial substitution actually improves strength, and ease of pumping of the of Portland cement during construction. These admixtures are concrete. Fly ash is also used as an ingredient in brick, block, often added to modify

UTILIZATION OF POND ASH AS PARTIAL REPLACEMENT OF CEMENT

of pond ash as partial replacement of cement concrete mix. These days coal based power plant are very popular, which generates large amount of fly ash, bottom ash and pond ash. The disposal of the fly ash is big challenge from environmental point of view. This study combines the work done in this area by various researchers and shows the effect of addition of pond ash on different properties

01/12/2017 This paper presents benefits resulted from various ratios of rice husk ash(RHA) on concrete indicators through 5 mixture plans with proportions of 5, 10, 15, 20 and 25% RHA by weight of cement in addition to 10% micro- silica (MS) to be compared with a reference mixture with 100% Portland cement. Tests results indicated the positive relationship between 15% replacement of RHA with increase in

The concrete formulations were prepared with a constant water–cement ratio 0.51. It was observed in hot weather that the workability of concrete mixes containing coal waste aggregate and control concrete was 35-65% less than normal climate. The average compressive strength of all the concrete mixes containing coal waste (CW) aggregate increased by 6% and 5% at 7 and 28 days, respectively

Concrete construction offers a great opportunity to replace the cement with a coal-based power plant waste—known as coal bottom ash (CBA)—which offers great environmental and technical benefits. These are significant in sustainable concrete construction. This study aims to recycle CBA in concrete and evaluate its particle fineness influence on workability, compressive and tensile strength
