Experimental Investigation on High Performance Concrete with Partial Replacement of Cement by Fly Ash and Fully Replacement of Sand by Stone Dust Student of Final Year Structural Engineering, Mandava Institute of Engineering and Technology, Andhra Pradesh Assistant Professor, Civil Engineering
The necessity of high performance concrete is increasing because of demands in the construction industry. Efforts for improving the performance of concrete over the past few years suggest that cement replacement materials along with Mineral chemical admixtures can improve the strength and durability characteristics of
important impact on environment and humans. This experiment describes the feasibility of using the steel shot dust in concrete production as partial replacement of cement. Test results show that upon using this steel shot dust; this industrial byproduct is capable of improving hardened concrete performance. The compressive strength of concrete
the natural sand in concrete control mixes of M25 and M30 grades designed for 100 to 120mm slump at replacement levels of 30%, 40%, 50% and 60% using Portland Pozzolana Cement. There were in all 5 mixes in each grade of concrete including control mix and four mixes with crusher dust as a partial replacement of natural sand.
study sand is replaced by marble dust, and then concrete was prepared. The replacement ratios which have been studied were %, 10%, 20%, 30%, 40%, and 50% by weight. Water – cement ratio kept Concrete made with marble dust as sand replacement achieved better performance compared to normal concrete.
partial replacement of cement by SF (from 5% to 10% with a step of %) on M20 grade concrete designed with 53 grade Ordinary Portland Cement, sand and coarse aggregate. As SF is costlier than cement, addition to cement will further enhance the cost, which may not be economically viable. The present study has, therefore,
performance of concrete by replacement of sand by steel dust. Mining crushers mainly include jaw crusher, cone crusher, impact crusher, mobile crusher for .

Performance of Ground Granulated Blast Furnace Slag Concrete with Partial Replacement of Sand by Saw Dust 1Manjit Kaur, ... 64%, %, % Replacement of sand by saw dust reduce the unit weight of concrete and make it light weight. The cost of concrete also decreases with the increase in percentage of saw dust.
on evaluation of the use of air cooled steel slag as a replacement for natural aggregate in concrete pavements. The steel slag from basic oxygen furnace was been used for the study. Compressive strength tests were conducted on samples with slag ratios of 0, 25,50, 75 and and cement contents of 200, 300 and 350 kg/m3.
concrete production" concluded that the combined use of quarry rock dust and marble sludge powder exhibited excellent performance due to efficient micro filling ability. 5. Prof. Shirule, Ataur Rehman, Rakesh D. Gupta, " Partial replacement of Cement with Marble dust powder"
of sand is replaced by quarry rock dust in concrete. Rajamane et al (2003) studied the properties of high performance concrete with partial replacement of cement by GGBS. They found that the compressive strength of concrete increased by MPa at 28 days age compared to conventional concrete. Ilangovan et. al. (2008) studied

Experimental study of concrete made with granite and iron powders as partial replacement of sand. ... conducted tests on granite powder as a partial sand replacement in high performance concrete and showed the beneficial effects on its mechanical properties. Of all the six mixtures he considered, concrete with 25% of granite powder (GP25) was ...
The suitability of quarry dust as alternative material for the river sand in concrete manufacturing is studied. M25 grade concrete was prepared with 0%, 20%, 40%, 60%, 80% partial replacement of ...
Research Paper PARTIAL REPLACEMENT OF CEMENT WITH MARBLE DUST POWDER Prof. Shirule a*, Ataur Rahman b, ... of improving hardened concrete performance up to 10%, Enhancing fresh concrete behavior. 30 cubes ... except Marble Dust Powder. Sand was obtained from Girna river which gray blackish in colour.
After mixing, workability of the concrete was determined using slump test. It was confirmed that the slump values of concrete at different glass replacement level remained within the target slump range of 100–125 mm without changing the water content. The concrete was placed, compacted and surface finished with a smooth steel trowel in cube mold.

Many efforts have been made to use waste glass in concrete industry as a replacement of coarse aggregate, fine aggregate and cement. Its performance as a coarse aggregate replacement has been found to be nonsatisfactory because of strength regression and expansion due to alkalisilica reaction.
a reduction in strength with an increment of saw dust ash. But while adding steel fibre to SDA, it is observed that the fibre reinforced saw dust ash (FRSDA) concrete has an increase in strength twice than that of the SDA concrete at 3rd, 7th and 28th days. Keywords: Saw dust ash concrete, saw dust ash, steel fibre, mix
