Get PriceUse of Quarry rock dust as a fine aggregate in concrete draws serious attention of researchers and investigators. This paper presents the feasibility of the usage of Quarry Rock Dust as hundred percent substitutes for Natural Sand in concrete. Tests were conducted on cubes to study the strength of concrete made of Quarry Rock Dust and the results were compared with the .
Get PriceThe strength achieved in concrete made with sand as fine aggregate achieved high strengths when compared with Quarry stone dust concrete. However, in both the cases strengths were falling at a super plasticiser dosage of % by weight of cement. Similar behaviour was also observed in cubes of M40 grade cubes. 3.
Get Price· It was reported that quarry dust as a replacement for fine aggregate in concrete increased the strength of concrete tremendously by up to 8–20% [ 32 ]. Hamid et al. [ 29] highlighted that the addition of quarry dust above 50% as replacement material will yield a negative effect on concrete compressive strength and workability.

Get Price· According to the past results, the QD was subjected to a sieving process to obtain fine aggregate grading. The grading complies with the international standard. Singh et al. (2016) and Hunger and Brouwers (2008) reported that the QD was angular and rough in texture.
Get PriceThe quarry dust is used as the first fine aggregates. 3. Since sand is much costlier due to reduction of sources IV. Sand: as natural fine aggregate, we need to find a replacement Sand is used as the second fine aggregates. The locally product with less cost.
Get PriceFine aggregates are the structural filler that occupies most of the volume of the concrete mix formulas. Depending on composition, shape, size and other properties of fine aggregate you can have a significant impact on the output. The role of fine aggregate can be described in few points: Fine aggregates provide dimensional stability to the mixture

Get Price· Further when fly ash is partially replaced with cement from 0 to 30% in mortar with 20% quarry dust (QF series), there is an overall increase in strength at 3 days, 7 days, and 28 days of age. The drop in compressive strength due to conversion reaction decreases with increase in fly ash content for a given water to powder ratio.
Get PriceThe values show that the river sand has a small range of particle size whereas the quarry dust has a wider range of particle sizes. Both aggregates fall into zone 2 of the grading requirements for fine aggregates and are suitable for producing concrete mix [10]. Figure 1:Particle size distribution curves for river sand and quarry dust.
Get Price· The chemical composition of the materials used is presented in Table 1 and is seen that limestone dust has higher concentration of CaO, while quarry dust fine aggregate and oven dried alum sludge indies higher concentration of SiO 2 among other chemicals present in the materials. Table 1.
Get PriceFine aggregate can be replaced up to 60% by Quarry Stone concrete mix, beyond 60% the strength of concrete starts decreasing compared with control mix. It is observed that maximum compressive strength of M25 and M30 concrete achieve at 60% of replacement
Get Price(2012):The workability of concrete using lateritic sand and quarry dust as fine aggregates was found to have the same trend with normal concrete. The density of hardened concrete using lateritic sand and quarry dust was found to range from kg/m3. NEED OF WORK
Get Price· Granite dust is regarded as a valuable and easytoobtain alternative for customary, natural fine aggregate. However, granite dust can be employed in engineered cement composites (ECC). Nevertheless, multiple health and environmental hazards are attributed to it, due to the fact that it is a nonbiodegradable material. The current study, however, has .
