quarry dust. In this test the replacement of cement in concrete with quarry dust are 0%,10%,20%,25%,30%,40% and M 30 grade concrete cubes of size …
Ebrahim ( 2018) studied the mechanical behavior of C25 and C30 grade of concrete by partially replacing cement with quarry dust by 5%, 10% 15% and 20% (PPC and OPC). The optimum replacement of cement by quarry dust recorded from the findings was 5% and 10% for PPC and OPC, respectively.
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.

mixes incorporating limestone or quarry dust were compared. It was found that the quarry dust, as supplied, could be used successfully in the production of SCC. However, due to its shape and particle size distribution, mixes with quarry dust required a higher dosage of super plasticizer to achieve similar flow properties.
quarry dust concrete is 10-12% more along with durability under sulphate and acid action. It also shown that the water absorption property of this concrete is slightly higher and …
quarry dust concrete is 10-12% more along with durability under sulphate and acid action. It also shown that the water absorption property of this concrete is slightly higher and lastly they have conclude that the replacement of natural sand with quarry dust, as full replacement in concrete is possible. To decide the water content and mix ...
One of the major environmental concerns is the disposal of the waste materials and utilization of industrial by products. Lime stone quarries will produce millions of tons waste dust powder every year. Having considerable high degree of fineness in comparision to cement this material may be utilized as a partial replacement to cement.
In this context, the paper reviews the strategies proposed in the use of limestone fine waste, especially for concrete, and discusses an experimental program intended to assess the mechanical properties of concrete made with the fine limestone waste produced in the area of Trapani, as a partial substitute of fine aggregate (sand).
It was observed that the compressive strength and split tensile strength increased up to 40% of quarry dust and then reduced. So, it can be concluded that the optimum percentage of red mud was 20% in cement, whereas the optimum percentage of quarry dust was 40% in concrete.
Cement Kiln Dust (CKD) is a by product material of cement manufacturing industry.The physical and chemical characteristics of CKD depend on raw materials, type of kiln operation, dust collection systems and fuel type used in cement clinker production. Free lime is found in CKD.
WM as partial replacement of sand was measured af ter 7-, 28-, 56-, and 90-day curing periods. e outcome Fig. 9 Relative compressive strength (Pala et al., 2015 )
Cement and fine aggregates were partially replaced by red mud and quarry dust. Different proportions of red mud such as 0, 5, 10, 15, 20, 25 and 30% in cement mortar were used. From the compressive strength point of view, the optimum percentage of red mud in cement mortar was recommended as 20%.
attempts to understand the influence of filler materials such as lime stone powder and quarry dust as a partial replacement of cement material. Self-compacting concrete …
Quarry dust generally produced in machine related to the processing of stone. This is non-biodegradable waste and causes damage to the soil. Therefore, need …
For both cases with or without the inclusion of mineral admixtures, the partial replacement 66 of sand with quarry dust resulted in a reduced 65 compressive strength compared to the control concrete 64 with no quarry dust. Similar findings have been reported 63 is …
Abstract The objective of the present project work is to study the behavior of concrete in partial replacement for cement with quarry dust in proportions. Quarry …
The 'ash' is recovered from the gases and used, amongst other functions, as a cement substitute. Fly ash can only be used as a partial replacement for cement because it relies on the water and lime …
For 28 days of curing, partial replacement of fine aggregate with 20-50% quarry dust content resulted to optimum compressive …
attempts to understand the influence of filler materials such as lime stone powder and quarry dust as a partial replacement of cement material. Self-compacting concrete was produced by partially replacing the cement by 10%, 20%, 30% Lime stone and Quarry dust powder, and their influence on fresh
limestone fines in the production of Portland limestone cement. An experimental investigation is thus carried out to examine the impacts of adding these fines on the physical and chemical properties of the cement paste such as consistency, setting time, and compressive strength. The main objectives of the study described in this paper are, thus to:
This research was conducted to examine the potential of basaltic crusher dust as a partial replacement for Portland Pozzolana cement in hollow concrete block …
In the second case study, construction block producers incorporated MIBA and also mixed ash (MIBA and municipal incinerated fly ash—MIFA) as a partial aggregate replacement in mixtures of 1%–3% cement, 25%–50% furnace bottom ash, 25% aggregate and water ( …
They have investigated first quarry dust is made partial replacement of cement and found that 25% of partial replacement is beneficial to concrete without loss of standard strength of cement. They have made 25% partial replacement of cement with quarry dust as constant, 2.5%, 5.0%, 7.5%, 10.0%,
CCA was used as partial replacement of cement ranging from 0% to 20% by weight at water-cementitious ratio of 0.6 and mix proportion of 1 cementitious: 3 fillers. The physical properties evaluated for the mortar paste were setting time and consistency; and compressive strength of hardened mortar cube.
This research was conducted to examine the potential of basaltic crusher dust as a partial replacement for Portland Pozzolana cement in hollow concrete block (HCB) production. Quarry dust is one of the waste materials abundantly available and pozzolanic material in the quarry industry. In doing so, physical tests of cement pastes …
During production and hydration process of cement, carbon dioxide CO 2 is produced which causes serious environmental damages and that can be prevented by partially replace of cement with...
This paper deals with the utilisation of alternative materials, such as quarry dust, for SCC applications. Results from rheological measurements on pastes and concrete mixes incorporating limestone or quarry dust were compared. It was found that the quarry dust, as supplied, could be used successfully in the production of SCC.
In this respect, the utilisation of quarry dust could play a part in lowering the supply cost of SCC, which is currently some 80–150% higher than that of normal concrete. In Sweden, the application of SCC is well established and according to Petersson [16], the cost of SCC is only 10–15% higher, while in France [17] the cost is 50– ...
