the concrete composition can also be suitable for partial replacement (up to 60%). the fly ash, quarry rock dust can be used form 20% replacement of cement and fine aggregate in concrete. it was concentrated to avoid environmental degradation due to industrial wastes form cement factories.
Quarry dust has rough, sharp and angular particles, and as such causes a gain in strength due to better interlocking. Quarry dust has been identified as possible replacement for sharp sand in concrete works. Jayawardena and Dissanayake [4, 5] in their paper Use of quarry dust instead of river sand
replacing sand with crusher dust in concrete blocks. work is an attempt to use Quarry Dust as replacement for Sand. 8230; dust as partial replacement for sand in hollow block in brick and block making
clear picture that quarry dust can be utilized in concrete mixtures as a good substitute for natural river sand giving higher strength at 50% replacement. Index Terms Concrete, quarry dust, river sand, compressive strength. I. INTRODUCTION oncrete is the most widely used composite material today.
#0183;#32;The demand of natural sand in the construction industry has increased a lot resulting in the reduction of sources and an increase in price. Thus an increased need to identify a suitable substitute, that is ecofriendly and inexpensive quarry dust being extensively used as an alternative to the sand in the production of concrete. In this paper an attempt has been made to determine the
studies of concrete made of quarry dust shown results that are nearly 10% more than the conventional concrete. In large scale, Quarry dust is used in the highways in the form of surface finishing material and also, in producing of hollow blocks and lightweight concrete prefabricated elements. QUARRY DUST AS PARTIAL REPLACEMENT OF CEMENT:
collected, the value is high and it show that quarry dust suitable to use as sand replacement. All the value of compressive strength surpasses the minimum value of compressive strength for normal concrete that is 7N/mm . So, quarry dust can apply as sand replacement in concrete mix for construction industry.
#0183;#32;This experimental study presents the variation in the strength of concrete when replacing sand by quarry dust from 0% to in steps of 10%. M20 and M25 grades of concrete were taken for study keeping a constant slump of 60mm. The compressive strength of concrete cubes at the age of 7 and 28 days were obtained at room temperature.
Partial Replacement of Sand with Quarry Dust in Concrete. 254. Partial Replacement of Sand with Quarry Dust in. Concrete. Chandana Sukesh, Katakam Bala Krishna, requirement for reduction in the cost of concrete production has. The cement that is
Effect of Marble Powder and Quarry Dust as Partial Replacement for Fine Aggregate on Concrete written by Dr. M. Kannan, Sandhya, Swarnalakshmi published on 2019/11/22 download full article with reference data and citations
They found in their study on suitability of quarry dust as partial replacement for sand in hollow block production that quarry dust is cheaper than River Benue sand during rainy season. Sridharan et al [13] conducted shear strength studies on soilquarry dust mixtures and observed that 2025% of the total
Optimum utilization of Quarry dust as partial replacement of sand in concrete. Lohani this crisis, partial replacement of sand with quarry dust can be an economic alternative. in the aspects of reduction in environmental load amp; waste management cost, reduction of production cost as well as autoclave blocks. 2.

This present work is an attempt to use Quarry Dust as partial replacement for Sand in concrete. Attempts have been made to study the properties of concrete and to investigate some properties of Quarry Dust the suitability of those properties to enable them to be used as partial replacement materials for sand in concrete.
#0183;#32;Granite fines or rock dust is a byproduct obtained during crushing of granite rocks and is also called quarry dust. In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically available.
A range of 0%, 10%, 15%, 20% and 25% sand replacement with quarry dust was used in the cement: sand mix ratios of 1:6 and 1:8 for molding the blocks of size 450mm x
