Use of coal ash as geopolymer binder and coarse aggregate,
15/10/2015· The fly ash (FA) and bottom ash (BA) were from Mae Moh power station in the north of Thailand. FA was used as a source material for making geopolymeric binder and BA was used as a coarse aggregate. The results of the XRF analysis of the coal ashes are shown in Table 1. FA can be classified as high calcium fly ash according to ASTM C618.

01/01/2000· The fly ash (FA) was obtained from Drax Power station in Yorkshire and conformed to BS 3892 [5]. Quartzitic sand and gravel were used as natural aggregates. The sand grading was medium (zone M) and the gravel had a maximum nominal size of 14 mm, both conformed to BS 882 [3]. RAP aggregate was obtained from Tilcon North while they were reconstructing a
Manuscript a coarse bauxite residue Submission
Coarse Bauxite Residue for Roadway Construction Materials Authors:, Class F fly ash (ASTM, 2000) was obtained from the Collie Coal Power Station. Its specific gravity was 2.03. Particle size classification indicated 17% clay, 68% silt, and 15% fine sand. The fly ash exhibited non-plastic behaviour and was grey in colour. The chemical analysis was 48% SiO2, 29% Al2O3, 12.7%
Effectiveness of bagasse ash for performance improvement,
25/03/2021· The performance of asphalt concrete pavements (ACP) is greatly related to the rate of rutting. Stone dust is mostly used as a filler in ACP. Bagasse ash being cementitious in nature, and costless waste can also be used as a filler. The overall aim is to select a suitable filler for better performance of asphalt concrete pavements. The effectiveness of locally available

mixes. Aggregate created by this recycling process is known as recycled concrete aggregate or crushed concrete coarse aggregate. Concrete is commonly recycled in this manner from the demolition of buildings and pavements [1]. Apart from impurities that may be present in aggregate of this type due to the wide variety of sources, the presence

amounts of sand and coarse aggregate are the opposite of what is used in conventional concrete, with the sand being 50 to 55 percent of the aggregate weight and the coarse material being 45 to 50 percent. The range of water to cement ratio in RCC mixtures can be as low as 0.36 and as high as 0.45, but it is effectively a result of the optimum
