UPV increased with an increase of fly ash, cement and quarry dust. On the other hand, addition of FA+BS was found to decrease UPV. (5) The optimum ratio of fly ash and billet scale, quarry dust and billet scale is found to be 1:1 since it showed the best performance with regard toPartial Replacement of Cement with Quarry Dust and Rice,,quarry dust with cement gives the compressive strength of 41.5N/mm^2 and after that it goes on decreasing when compared to conventional without any replacement of quarry dust. It is clearly observed that addition of quarry dust up to certain extentImplication of Metakaolin in Quarry Dust Concrete,initiation time of quarry dust concrete with various percentages of metakaolin have shown in Fig. 6 and Fig. 7. It is found from Fig. 6 that the time to initiate corrosion for quarry dust concrete was found to be 160 hours. Quarry dust concrete with 5%, 10%, 15% and 20% replacement of cement“Green Concrete: Using Industrial Waste of Marble Powder,,QUARRY DUST: The consumption of cement content, workability, compressive strength and cost of concrete made with quarry dust were studied by researcher Babu K.K. et al.[2]. The mix design was proposed by Nagraj et al.

Therefore the concurrent use of quarry dusthow to mix concrete with quarry dust - educationcare,experimental investigation on quarry dust concrete with chemical,found that quarry dust improves the mechanical properties of concrete when used along with,mixture of the materials results in a chemical reactionCement dust exposure and acute lung function: A cross,,Few studies have been carried out on acute effects of cement dust exposure. This study is conducted to investigate the associations between current "total" dust exposure and acute respiratory symptoms and respiratory function among cement factory workers. A combined cross-sectional and cross-shift study was conducted in Dire Dawa cement factory in Ethiopia. 40 exposed production workers from,Marble and-quarry-dust-as-additives-in-concrete,marble slurry dust as cement additive , The research on the use of marble dust in concrete , ,,the total voids content in concrete This contributes to improve the strength of concrete Marble sludge powder and quarry rock dust improved pozzolanic reaction,,EXPERIMENTAL INVESTIGATION ON PARTIAL REPLACEMENT OF,,The ingredients of concrete consist of cement, fine aggregate and coarse aggregates, water. When the reaction of water with cement takes place hydration process is done and a hard material is formed. In this project work we used quarry rock dust as a partial replacement of fine aggregate and fly ask replaced by cement.
