The maximum fresh and dry densities are maximum for concrete mixes containing 40 crusher dust as partial replacement of natural sand. The increase in density might also be increasing the compressive strength due to better particle packing.
The ratio of dry volume to the wet volume of concrete is 1.54. So 1.54 Cum of dry materials cement, sand and aggregate is required to produce 1 Cum of concrete Volume of Cement required 1 124 X 1.54 17 X 1.54 0.22 Cum Volume of Sand required 27 X 1.54 0.44 Cum or 15.53 cft.
An attempt has been made through this study to find out a suitable mix proportion of desired strength by replacing sand with crusher dust in cement concrete, at the same time retaining its quality .

Concrete of M25 grade was designed for a wc ratio of 0.48 for the replacement of 10 coarse aggregate with recycled coarse aggregate and replacement of 50, 60 and 70 of fine aggregate sand.
The rapid development of urbanization has resulted in the accumulation of a large amount of waste concrete, which not only occupies land resources but also pollutes the air and the environment. Therefore, the recycling of waste concrete has become an important issue that the government needs to solve.
Abandoned concrete blocks are high-quality concrete aggregates which have many advantages. For example, after the buildings are dismantled, the high-quality concrete blocks and silt after crushing and screening can be used as recycled coarse and fine aggregates for concrete. The fine powder can be directly used as the raw material of cement. The concrete prepared from recycled cement and recycled aggregate can enter the next cycle, which realizes zero waste discharge throughout the whole cycle.
Concrete, cement and other wastes in construction waste can be used as building aggregates and recycled brick raw materials after being reasonably crushed, screened and crushed. And the main equipment used for crushing concrete can be divided into two types traditional fixed crusher and mobile concrete crusher, among which small crushing equipment is favored by users.
Although the compressive strength and hardness of concrete are not high, due to the porosity and the formation type, the concrete has good toughness and can buffer the crushing force, which causes low crushing efficiency. So, what kind of crusher should be selected for concrete crushing In the process of crushing waste concrete, according to the working principle of more crushing and less grinding, it is necessary to carefully configure the concrete crusher equipment.nbsp.
Jaw Crusher, also known as concrete crusher, is usually used as the primary equipment for concrete crushing. It is also suitable for metallurgy, mining, construction, chemical, water conservancy and railway sectors, and used as a device for fine and medium crushing of ores and rocks with compressive strength below 250 Mpa.
In recent years, the small jaw crusher has been favored by foreign users because of its small size, easy transportation and installation, low price, and fast profit. The models like PE-150250, PE-200350 and PE-400600 have become the best choice for customers to crush concrete.
After the rough breaking, steel and iron equipment are added to remove the steel bars and iron blocks in the waste concrete, which will eliminate the damage of steel bars and iron blocks to the equipment without affecting the production. Generally, the impact crusher, the fine crushing jaw crusher or the cone crusher is used as the secondary crushing to crush the material to less than 2 cm, and the selected granularity can be basically achieved.
For smaller discharge sizes, a three-stage crusher can be used, for example, the fine crushing crusher or the roller crusher is used to further crush the ore to less than 10 mm. In the actual production, the suitable crusher can be selected according to the size of the concrete block. It can be combined in single or multi-machine operations, both of which have the characteristics of simple operation, strong controllability and high production efficiency.
In the international environment of the crusher industry, besides the traditional jaw crusher, high-efficiency and environmentally-friendly construction concrete crusher will be the trend of future development.
In view of the characteristics of concrete waste, Henan HXJQ Machinery designed a concrete crushing equipment-mobile concrete crusher. The waste concrete after crushing can be used for reinforcing the foundation, producing bricks, cement, etc, not only achieving its values but also solving the issue of land and environment problems, which can be described as two-fold.
Two grades of concrete M20 and M25 having nominal mix proportion of 11.53 and 112 respectively were used by weight and wc ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0 to 100 in step of 10.
Apr 17, 2013nbsp018332Concrete Mix Ratio Buzzle. 27 Sep 2011 The normal ratio of concrete mixture is 6 air, 11 Portland cement, 41 gravel, 26 sand and 16 water. and 112, which imply the ratio between, cement, aggregate and water. and is exposed to gravitational force, the 112 ratio has to be used, plus RCC, in cases where structures are involved. 187More detailed.

Grade concrete. Control concrete was designed using sand as fine aggregates. Quarry dust concrete was designed by 100 replacement of sand. M15 grade quarry dust concrete were designed with four different water cement ratios and are designated as M15QD.65, M15QD.6, M15QD.55, M15QD.5 .
In effort to find a good answer Ive been all over the internet looking for an answer to exactly how thick of a layer of crushed rock and how thick of a layer of sand to use for a patio. Or at the very least what the ratio should be.
The difference in answers is enough for me to not be able to make a good choice. Not wanting to have it too thin is my main goal. Seeing as Ive already moved 1600 5 to 8 lb ea, 4x4x8 bricks by hand to where the patio is going to be, Im not really all that worried about moving a ton or so of crushed rock. Whats a little more of a workout right Im also not trying to skimp. If I need 4 inches of crushed rock, then Im doing it.
Yes, M-Sand crushed sand can replace 100 river sand in a concrete mix proportion. M-Sand are manufactured by latest technology Vertical shaft impactor nachines. They give at par results in comparison to rivers sand concrete mixes, in both fresh and hardened state. Since quality control is maintained in the process of preparing manufactured sand, the.
Also one of my neighbors who is a landscaper joked about how far I had dug down he said I went way too deep and now I can land a helicopter on my new patio. I tend to agree with him that the 4 inches of paver base was more than needed but still I am happy with how it all turned out.
Ive been installing pavers for over 35 years and have maintained a semi of pavers a day for our production. I have to tell you that the more sand you use the more problems you will have.
The best is 12 inch This way the sand wont filter out over time leaving you with uneven surfaces. I cant believe some sites are stating to use up to 2 inches of sand Stop the madness.
I am a respected installer and have even created the UNIBASE system, which is a cement base brick paver installation that holds a lifetime warranty.
Lowes produced a video that suggests 4 of rock and 1 leveling sand.
Jun 12, 2010nbsp018332Hi, Would like to know if there any problems using crusher dust for my concrete instead of sand and gravel, the crusher dust has a fair bit of powder so it mixes ok but im want to use it for footings for raised floor of ganny flat, was going to use mix of 41 have used it for chooks pens etc and seems alright but dont know how strong it is to use for house footings. thanks Rick.
