Housing Building Materials in Uganda. New technologies such as interlocking stabilized soil blocks (ISSB) have not been .... waste, etc. are mixed with either sand or stone quarry dust, along with cement and water. ... by mixing calcium hydroxide (lime) and pozzolana in the ratio of 1: or 1: 2. ...
Experimental programme was conducted using 30%, 40%, 50%, 60% and 70% partial replacement of fine aggregate with stone dust has been taken for concrete of M25 grade with water cement ratio.
age compressive strength of concrete cubes made with quarry dust. There is approximately 12% increase on average compressive strength of concrete made with 50% quarry dust and 50% sand as compared to that made of sand (control)attheendof21days. AccordingtoNeville,concreteofgradeC20at28daysmust achieve a compressive strength of 20MPa.
In order to reduce the content of cement in concrete we are replacing cement with metakaolin, sea wage and sand with quarry dust, Msand which will improve the strength and durability. To protect the depletion of natural resources, pozzolanic material is replaced in concrete. This research is done to
Quarry Dust Fine Powder as Substitute for Ordinary Portland Cement in Concrete Mix 193 Journal of Engineering Science and Technology April 2014, Vol. 9(2) enhances compressive strength at hardened state [3]. However, there is still limited information on the behaviour of concrete properties with the inclusion of different
(c) The compressive strength results of quarry dust concrete (cubes) were obtained in the third series, where M20, M25, and M30 grades of concrete with 20, 25, and 30 percent replacement of quarry dust and also workability are studied by varying the watercement ratio .
investigated the partial replacement of sand with quarry dust. Initially cement concrete cube was studied with various proportions of cement concrete + quarry dust (M 20, AND M25). The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.

The experimental results showed that the addition of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties.
As the ability to use natural sand in cement mixtures declines, there has been an increased interest in the potential of quarry dust to replace it. Quarry dust is a waste product produced during the crushing process which is used to extract stone, and there is a great deal .
and flexural strengths besides durability of concrete made with Quarry Dust have been investigated. Cement Concrete mix using Quarry Dust as Fine Aggregate is designed using M20. Combinations used for this study, i. Concrete using natural sand as fine aggregate. ii. Concrete using 75% natural sand and 25% Quarry Dust. iii.
Samples of concrete (eg. cylinders, beams) were made using varying contents of lateritic sand and quarry dust as fine aggregate. The proportion of lateritic sand was varied from 0% to against quarry dust at intervals of 25%, using concrete mix of 1::3 and water/cement ratio of Concrete samples were prepared, cured for 28 days, and
Quarry Rock Dust: Quarry rock dust is a waste material obtained from stone quarries while crushing stones, stone crusher dust, which is available abundantly from crusher units at a low cost in many areas, provides a viable alternative for river sand in concrete. Table 5 physical properties of quarry rock dust . Property Value Obtained 1.
The proportion of 25% laterite to 75% quarry dust and 50% laterite to 50% quarry dust with water cement ratio produced workable concrete with good structural characteristics; iii) The density of hardened concrete using lateritic sand and quarry dust was found to range from Kg/m3.
cement ratio (w/c) which gives the slump of 60mm was selected from graph. The various w/c for different proportions of sand and quarry dust was presented in Table 2. Table 2: Workability of concrete ( slump 60mm) Fine aggregate Sand: Quarry dust water cement ratio ( w/c ) M20 M25 100:0 90:10 80:20
developed for four different proportion of quarry dust in concrete. Tests were conducted on cubes to study the compressive strength of concrete made of quarry dust and results were compared with the control concrete. It is found that the compressive strength of concrete made of quarry dust .
under taken to produce low cost concrete by blending in various ratios of hypo sludge with cement. 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.
Key word: Quarry dust, river sand, compressive strength, water cement ratio, workability. 1. INTRODUCTION Concrete is a mixture of water, cement or binder and aggregates (fine and coarse aggregate) and is a commonly used material for construction (Barritt, 1984). River sand has been the most popularly used fine aggregate in the production
Stone dust is not used in good concrete especially in '' Controlled Concrete ''. Use of Stone dust is going to drastically reduce the workability of concrete. This is so because the stone dust particles are not rounded like natural sand particles bu...
of quarry dust with watercement ratio of are It is observed that there is consistent increase in the studied and the results are presented. strength of plain concrete when natural sand is fully replaced (e) In the ith series, M20 grade of concrete with 10 by quarry dust (Chitlange and Pajgade [9]).
quarry dust for the same w/c ratio. Concrete does not give adequate workability with increase of quarry dust. It can be due to the extra fineness of quarry dust Increased fineness require greater amount of water for the mix ingredients to get closer packing, results in .
The usage of quarry dust in bond and cement gives ... concrete. Quarry dust is a byproduct that is generated from the ... performance as the control mixture, especially at low w/b ratios ( and ). Higher copper slag (%) replacement yielded lower strength values. Results also demonstrated that .
quarry dust concrete with water cement ratio showed same slump as that of control concrete with w/c From the compaction factor values shown in table 7 and table 8 we can see that Quarry dust concrete with water cement ratio and showed better compaction than control concrete with water cement ratio
Quarry dust has been proposed as an alternative to river sand that gives additional benefit to concrete. Quarry dust is known to increase the strength of concrete over concrete made with equal quantities of river sand. The Compressive strength of quarry dust concrete continues to increase with age for all the percentage of quarry dust contents.
