step 6: break concrete into smaller pieces. trying to crack off large pieces will only result in the jackhammer getting stuck. the key is to look for cracks and broken chunks of concrete, then work the breaker along those lines. the best approach is to break the concrete up in the pattern of a grid.
a shovel can be used to lift all the resulting broken pieces of concrete to make it easier to dispose of them. this method will be particularly effective on relatively thin paving slabs. connecting the head of the hammer to strategic points, such as corners and edges, will make it easier to work on thick concrete in order to break it up. 5
the aggregate particle size is determined by using wire-mesh sieves with square openings. the seven standard astm c f33 sieves for fine aggregate have openings ranging from 150 μm to 9.5 mm. the 13 standard sieves for coarse aggregate have openings ranging from 1.18 mm to 100 mm.
concrete removal, rock breaking and stone quarrying, mining has never been easier with dexpan non-explosive demolition agent. dexpan is a cement with amazing 18,000 psi expansive strength when mixed with water. poured into pre-drilled holes, dexpan can crack and split concrete and rocks safely and quietly, while providing silent cracking.
these are the actual concrete mix ratios for 3000, 3500, 4000, and 4500 psi concrete that i use to pour concrete floors, patios, pool decks and more. i'll show you the actual concrete batch plant ticket with the cement, sand, and aggregate break downs for the yards we used.
once you break up the concrete to sizes you desire, pry them up from the ground. as i mentioned, we want this concrete for backfill, so we want smallish pieces and the look of them doesn’t matter. this patio sits higher in some spots than the surrounding grass, which makes it easy to pull pieces off the ground.
prop up the braces with wooden stakes. dig out the soil around the braces, then stand the stakes in them. you can use 2 in × 4 in (5.1 cm × 10.2 cm) wood for most projects. place the stakes approximately every 12 in (30 cm), then drill them to the braces with 3 in (7.6 cm) wood screws.
the pipe or hose diameter for a project should be at least three times larger than the diameter of the largest aggregate. so for instance, if the largest aggregate in a mix is 1 inch, the minimum diameter for the line is 3 inches. brown says the aggregate gradation of a concrete mix is also a concern.
during the curing process, the concrete should naturally contract slightly, pulling away from the forms and making it easy to pop them off. using a wooden wedge to help pry the form away from the concrete in order to avoid breaking the concrete edge. 6. rushing to pour concrete without proper site preparation.
looking for concrete pad thickness and dimensions - posted in observatories: hello, i am planning to pour a small pad in my back yard for my scope tripod and i am looking for guidance on the recommended thickness and dimensions. this pad is just for the tripod and i was thinking of making it triangular. i tried just the ground but the tripod legs tend to sink in.
put the aggregate into a thin topping. another alternative is to place a thin topping course of concrete containing the decorative aggregate over a base slab of conventional concrete. the topping can range in thickness from 1 to 2 inches, depending on the aggregate size.
a cubic yard of concrete will fill an area 8 feet wide by 10 feet long by 4 inches thick, or 80 square feet @ 4 inches thick. at 6 inches thick a cubic yard of concrete will fill an area 52 square feet and at 5 inches thick, it will fill an area that's 65 square feet. 4000 psi concrete mixing ratio
a fully functionally equivalent, looks identical, much less costly approach would be to dig nearly the same hole (or one 4'8'x4'8'), without worrying too much about digging out the middle, pour a 12'wide footing around the perimeter, pour a 4'x4' 8' thick wall on top of the footing, fill the middle with gravel/sand, and pour a 4'-8' slab on top.
select dimensions of the concrete structure e.g., beam, column, slab, footing, etc. (all dimensions should be expressed either in m or ft) unit: meter feet. length: width: height/ thickness: concrete mix: 1:1.5:3 1:2:4 1:3:6 1:4:8 1:5:10.
rebar is central to reinforced concrete, so a basic understanding helps. the various sizes are important to know: a #3 bar is 3/8” in diameter, a #7 bar is 7/8” in diameter, etc. the easy rule of thumb for rebar sizes is to take the rebar size and divide by 8 for the diameter in inches. rebar. diameter.
trusses and three concrete portal frames (dashed red lines in figure 2) are utilised. the portal frame ‘columns’ consist of 300mm thick, two storey shear walls. the portal frame ‘beams’ consist of 300mm thick, one storey (3.75m) deep walls. the storey-deep beams and the trusses are shown in figure 3.
a well-poured concrete slab with a deep, sturdy foundation can last for 30 to 40 years. pouring concrete over old concrete instead of directly over a new gravel foundation limits your ability to maximize the slab's lifespan. the condition of the existing slab is the primary factor that determines how long the new concrete will last.
its about 3.75 cu yards of crete, or like $400 it will cost $100 for gravel to fill in 2', but my crete is still only a little cheaper, and it will be a thinner slab. i could put gravel in, say 2' and 3.5' of concrete over that or just full 5.5' of crete or i could do lot of gravel and a 2' top coat over that with a
c. replacement concrete shall be thickness required to match existing concrete but not less than 4” minimum except at driveways. at driveways, concrete shall be a minimum of 8” thick, 5” thick sidewalk where concrete curb is provided, and shall be reinforced.
gravel size. one thing you always need to keep in mind is the size of the gravel you need. if you're patching a deep hole, say 3 inches or deeper, you can use 1-inch gravel. this gravel has pieces of stone ranging in size from large grapes to small green peas.
therefore m30 concrete will have a compressive strength of 30 n/mm2. a standard mix may also specify the maximum aggregate size. aggregates are the stone chips used in concrete. if an engineer specifies m30 / 20 concrete, he wants m30 concrete with a maximum aggregate size of 20mm.
.3 maximum aggregate size 20 mm .4 air entrainment 5.0 % to 8.0 % .2 concrete mixing .1 on site: concrete shall only be made on the site with the approval of the engineer. .2 ready-mixed: ready-mixed concrete shall be mixed and transported in accordance with
300–400 c approx. 350 c break up of some siliceous aggregates pieces of concrete that have thick- that micro-concrete with a larger aggregate size was more effective as a repair
in the upper range of our stone sizing – 4” down to 2”. this covers products such as rip raps, large beach pebbles, and red rock. their weight makes them a sturdy and excellent decorative stone, especially for creating borders and outlining gardens and driveways. in the mid range of our stone sizing – 2” down to 1/2”.
concrete blocks are often made of 1:3:6 concrete with a maximum size aggregate of 10mm or a cement-sand mixture with a ratio of 1:7, 1:8 or 1:9. these mixtures, if properly cured, give concrete blocks a compression strength well above what is required in a one-storey building.
follow these do’s and don’ts when ordering aggregates and asphalt to achieve the best results for your project. sand & aggregate. approximately 110 pounds per cubic foot; approximately 3000 pounds per cubic yard; aggregate deliveries are available by straight trucks or semi-trucks our straight trucks can hold up to 15 tons.
concrete breaking equipment & demolition rental. concrete demolition work calls for precision and care. so, failure to use the right tools and follow safety procedures can lead to major mishaps and injuries. as a result, your best bet is seeking help from concrete breaking equipment experts, instead of doing the work yourself.
they also usually carry three or four add on chutes. so the normal maximum total chute length is a little more than 16 feet, depending on the brand and model truck. actually depending on the mix design and slump concrete can travel down a chute up to 40 feet before aggregate segregation becomes a problem.
