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 ...
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
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
Whenever you work on a project that requires cutting, grinding or chipping concrete, you will make concrete dust. The primary ingredient of concrete dust is crystalline silica. According to Amicus, "For many years, it has been known that breathing in fine dust containing crystalline silica can cause lung damage (silicosis)."
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.
The incorporation of up to IO percent limestone dust as a partial replacement for fine aggregate in concrete with a watercement ratio and 5 percent limestone dust in concrete with a watercement ratio does not significantly affect the properties of fresh and hardened concrete.

Sep 27, 2016· The iron within the steel dust reacts with C02 and rusts to form iron carbonate. It''s this that is fused into the matrix of Ferrock and, like concrete, after it''s dried, it cannot be melted back into a liquid form but retains its hard, rocklike qualities. What are the advantages?
studies on green concrete compared with the natural sand concrete. It is found that the compressive, split tensile strength and durability studies of concrete made of quarry rock dust are nearly 14 % more than the conventional concrete. The concrete resistance to sulphate attack was enhanced greatly.
Abstract. This paper presents the results of an experimental investigation carried out to evaluate the compressive strength and transverse strength of 1 : 3 mortar mixes in which natural sand was replaced with 20%, 50%, and quarry dust by weight which were further modified by partially replacing cement with four percentages (15%, 20%, 25%, and 30%) of low calcium fly ash.
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"
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.
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,
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 ...

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.
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
