The maximum improvement in steel-concrete bond strength is recorded with 10.0% marble dust as a replacement for cement or as a replacement for sand. 12. The use of marble dust up to 15.0% by weight as a replacement for cement or as a replacement for sand has insignificant effect on the ultrasonic pulse velocity test values.
The concrete will have high compressive strength when using quarry dust in concrete, the compressive strength also increases. We have already started using quarry dust in our construction process, such as sand beds. Glass Particles. The crushed glass particles may be used in concrete …
river sand. Quarry dust and Marble powder contains similar properties as that of river sand and hence accepted as a building material. The present paper focuses on investigating maximum percentage replacement of river sand by Quarry dust and Marble powder in varying equal percentages 0%, 10%, 20%, 30%, 40%, 50%, and 60% for M25 mix designations.
Thus, it can be concluded that the replacement of natural sand with Quarry Rock Dust, as full replacement in concrete is possible. B. B. Patel (et al 2012) [6] The compressive strength of concrete increases with increase in content up to 7.5%. Thereafter there is slight decline in strength for 10%, 12% and 15% due excess amount of which ...

Partial Replacement of Sand with Quarry Dust in Concrete557 Кб. This present work is an attempt to use Quarry Dust as partial replacement for Sand in concrete.NEED FOR THE REPLACEMENT OF SAND I. INTRODUCTION Concrete is the most popular building material in the world.
investigation on strength of concrete and optimum percentage of the partial replacement by replacing cement via 0%, 10%, 20%, 30%, 40% and 50% of ceramic waste. Keeping all this view, the aim of the investigation is to study the behavior of concrete while replacing theceramic waste with different proportions in concrete.
STUDY THE EFFECT OF STONE DUST AS PARTIAL REPLACEMENT OF SAND ADDING STEEL FIBRE Sunil Kumar Verma M.Tech. Scholar Department of Civil Engineering Swami Devi Dyal Institute of Engineering and Technology, Panchkula, India Abstract: Nowadays, there is an increasing interest in the development of eco-friendly materials. Thus, environmental
It is found that 40% replacement of sand by quarry dust gives maximum result in strength compared to normal concrete and then decreases from 50%. The results proved that up to 40% replacement of sand by the quarry dust induced higher compressive strength and the workability of concrete decreases as replacement increases.
suitability of those properties to enable quarry dust (Celik et. al., 1996) to be used as partial replacement material for sand in concrete. The use of quarry dust in concrete is desirable because of its benefits such as useful disposal of by products, reduction of river sand …
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 ...
is used as 50% replacement as fine aggregate. [6]. The properties of concrete by replacing natural sand by manufacturing sand is higher. The higher level of fines in manufactured sand increases the workability decrease water content in concrete [7]. The steel slag when used as a replacement for coarse aggregate increases the
aggregate, and up to 80% replacement,concrete gain more strength than normal concrete strength. 3. It is observed that up to 30% replacement of natural sand by copper slag, the flexural strength of concrete is increased by 14%.and all percentage replacement of fine aggregate by
Instead of disposing them in landfills, it can be best utilized as partial replacement to sand. In crusher dust, the particles (% finer than 150 microns) are generally high, a major concern limiting its percentage replacement to minimum with sand in a concrete mix. It can be replaced to the amount 25%. Its Availability is not a concern.
Partial replacement of cement by Metakaolin and Quarry Dust by sand in concrete mixes would, not only lead to considerable savings in consumption of cement and natural sand 2. The ultimateload carrying capacity of High performance concrete beam using (10% Metakaolin and 30% Quarry Dust) is found to be 26kN, and 38 kN, at the age of 28,and 56 ...
Quality of sand is as much of importance as other materials for concrete. Aggregate most of which pass through 4.75 mm IS sieve is known as fine aggregate. Fine aggregate shall consists of natural sand, crushed stone sand, crushed gravel sand stone dust or arable dust, fly …
Table 3 The results show that there is an increase in the compressive strength of the concrete [3,4] which the increment is about 55% to 75% depending on the replacement if the sand with the quarry dust, for the replacement of the sand the compressive strength is depending on the quarry dust location from where the quarry dust was taken.

The incorporation of up to IO percent limestone dust as a partial replacement for fine aggregate in concrete with a 0.70 water-cement ratio and 5 percent limestone dust in concrete with a 0.53 water-cement ratio does not significantly affect the properties of fresh and hardened concrete. The loss in entrained-air content can be easily overcome ...
The investigation concludes that, as the replacement of the sand with quarry dust increases the workability of the concrete decreases due to the absorption of the water by the quarry dust. The specific gravity is almost same for both the natural river sand and quarry dust.
Alternative cementitious materials are finely divided materials that replace or supplement the use of portland cement. Their use reduces the cost and/or improves one or more technical properties of concrete. These materials include fly ash, ground granulated blast furnace slag, condensed silica fume, limestone dust, cement kiln dust, and ...
