The effect of % of Quarry dust and fly ash in cement concrete is studied in detailed. Test results for each variation are tabulated and discussed in details and some important conclusions are made. Keywords— Natural Sand, Quarry Dust, Fly Ash, Workability, Compressive strength, Split tensile strength, Flexural strength. INTRODUCTION
2% Quarry dust-53%. Key words : Fly ash, Lime, Gypsum, Quarry dust, Compressive strength and Water absorption. INTRODUCTION In the present scenario in the construction industry, use of economic and environmental friendly material is of a great concern. One of the main ingredients used is cement.
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. the results were encouraging in that they revealed that concrete of the required compressive ...
Rama Raju et al.  had made an attempt to use quarry dust and fly ash as partial replacement for sand and cement respectively in SCC and to investigate some properties of quarry dust and fly ash and the suitability of those properties to enable them to be used as partial replacement materials for sand and cement in concrete.
3.3. Test Results on Fly Ash Concrete with Quarry Dust Different levels of replacement such as 40% and 50% of fly ash and 10% and 20% replacement of quarry dust for compressive strength (Figure 9) and Tensile Strength (Figure 10) is shown below. a) Compression Test Figure 9. Compressive Strength against % replacement for 7, 28 and 56 days.
dust leads to a reduction in the workability of concrete. Therefore, concurrent use of fly ash and quarry dust in concrete will make the concrete by using their properties in a beneficial way. The decrease in early strength by the addition of fly ash is compensated by addition of quarry dust .The decrease in workability by the addition of
The optimum ratio of fly ash and billet scale, quarry dust and billet scale is found to be 1:1 since it showed the best performance with regard to mechanical properties. (6) Manufacture of bricks using a combination of billet scale, quarry dust and fly ash is feasible.
strength. Therefore, the concurrent use of quarry dust and fly ash in concrete will lead to the benefits such as, the decrease in early strength by the addition of fly ash is reduced by the addition of quarry dust and the decrease in workability by the addition of quarry dust is reduced by the addition of fly ash …
The results of the study also indicates that quarry dust can be utilised as partial replacement material to sand, in the presence of silica fume or fly ash, to produce concretes with fair ranges ...
Quarry dust has been proposed as an alternative to river sand that gives additional benefit to mortar. Quarry dust is known to increase the strength of concrete over concrete made with equal quantities of river sand, but it causes a reduction in the workability of concrete. When examining the above qualities of fly ash and quarry dust
Fly ash, Hydrated lime, Quarry dust and gypsum are manually fed into a pan mixer where water is added in the required proportion for intimate mixing. welcome to jayam fly ash. Jayam flyash bricks. Welcome to Jayam Fly Ash . Fly Ash Bricks are manufactured using thermal power station's fly ash, sand / quarry fines, lime and gypsum.
In M25 concrete mix 50% of cement was replaced by fly ash and sand was totally replaced by 50% of quarry dust and 50% of marble powder. Keywords:-Green concrete, fly ash, quarry dust, marble powder, compressive strength, split tensile strength.
In this study, partial replacement of cement by fly ash and quarry dust has been made in order to limiting the usage of cement and thereby it leads a way to reduce the cost of construction.
certain percentage of fly ash by quarry dust. The concurrent use of the two by-products will lead to a range of economic and environmental benefits. Quarry dust has been proposed as an alternative to river sand that gives additional benefit to mortar. Quarry dust is known to increase the strength of mortar over mortar made with equal quantities
Rama Raju et al. had made an attempt to use quarry dust and fly ash as partial replacement for sand and cement respectively in SCC and to investigate some properties of quarry dust and fly ash and the suitability of those properties to enable them to be used as partial replacement materials for sand and cement in concrete.
40% of fly ash and 50% of quarry dust and billet scale were used. For series D, 5% of cement, 70% of fly ash and 25% of quarry dust and billet scale were investigated in this paper. Mix design in this paper was done based on previous works . The quarry dust (QD) and cement (C) were firstly placed in a mixer and dry mixed for 2 minutes.
Quarry Dust or fine Sand use as binder material in fly ash brick production. Quarry dust is collected from the local distributers for the project work. Chemical composition of Fly ash and RSD waste The following table shows the chemical composition of fly ash
