It was concluded that the concrete made with 20% replacement of sand by crusher dust and 20% replacement of broken stone by gravel gave better results in terms of strength and cost It was also noted that up to 40% replacement of broken stone by gravel and 20% replacement of sand by crusher dust also gave better results than control concrete
This research work is concerned with the experimental investigation on strength of concrete and optimum percentage of the partial replacement by replacing PPC cement via 0% 10% 20% 30% 40%
Fig2 Compressive Strength of Different Concrete Mixes at Different Ages IV TEST RESULTS AND DISCUSSIONS 1 At 7 days curing period the compressive strength of concrete with 25% crusher dust is more than the controlled concrete by % 2 At 14 days curing period the compressive strength of concrete with 25% crusher dust is higher by %

I have plenty of crusher run already I was thinking about mixing the crusher run with Portland cement I don t need it to look good and peak strength isn t really a priority If I got even 1000 psi from the mix I would be happy I plan to load the crusher run and cement into a mixer and mix it not brush the cement dust on top of the gravel
strength of concrete by 5 22% It was also found that amongst all the mixes the highest compressive strength was obtained for 40% replacement of sand by crusher dust Hence it could be concluded and recommended that crusher dust could be effectively used in concrete of above grades for replacement
According to Neville [15] the results of rock strength tests indicate more the quality of parent rock than the quality of broken aggregate used for tests of strength and deformation properties of parent rocks crushed aggregates and concretes carried out among others by the authors [17] In most cases conformity was found between mechanical
Download Citation An Experimental Investigation of Sustainable Concrete by using Paper Pulp and Crusher Dust The objective of the research carried out in this paper highlights the critical
It uses kilowatts of Brokk SmartPower to handle attachments typically reserved for larger machines such as the BHB 305 breaker or the Darda CC480 concrete crusher This compact masterpiece offers incredible strength and reach making it unbeatable in its class
After conducting several trials we have arrived at a workable proportion with crusher stone dust with higher compressive strength than the established mix design M 25 using river sand Discover
Compressive strength is the key property of concrete [38] The Compressive strength of crusher dust concrete mixes evaluated by the several researches Pofale and Quadri [5] reported that compressive strength increased by 22% and 16% with the use of crusher dust at 40% replacement of fine aggregate
Fig 1 Compressive Strength of Concrete at 7 and 28 days Compressive Strength of Concrete with various re placement level of Crusher Sand Fig Split Tensile strength of Concrete at 28 Days CONCLUSIONS From the above experimental results it is proved that Crusher sand can be used as alternative material for
Compressive strength of concrete is believed to have a large impact on the energy required for crushing concrete based on the similar findings for crushing rocks natural stone Korman et al
The compact and powerful Concrete Crusher from Darda show their strength especially in indoor demolition in very confined spaces during operation or in busy environments but also as an all round Concrete Crusher in many other applications Work effectively and safely with significantly lower emissions compared to other demolition methods in
Self Compacting Concrete SCC has had a remarkable impact on the concrete construction industry especially the precast concrete industry Crushed Rock Dust CRD and Marble Sludge Powder MSP are discarded in the nearby land and the natural fertility of the soil is spoiled MSP and CRD can be used as filler and helps to reduce the total voids content in
5 Main Wear resistant Parts of PE Jaw Crusher 1 Jaw plate On the basis of the original high manganese steel Lutong s jaw plate is added with a certain amount of chromium element to improve the hardness of the The movable jaw plate and fixed jaw plate of jaw crusher can be used for crushing limestone compressive strength 150MPa for more than one year
Observation compressive strength increases after 7 days 14 days and 28 days for 10% replacement and after that it gets on decreasing as we increase the percentage V CONCLUSIONS 1 Maximum increase in compressive strength of concrete occurs at 10% of replacement of sand with crusher dust 2
