Whats the ratio of gravel (premixed sand and stone) to cement for making a good strong concrete mix for a wall foundation? Is 4 gravel to 1 cement a good/stong concrete mix for 450mm deep x 450mm wide wall foundations? Or is it 5:1? There will also be 8mm steel mesh in the foundation too (50mm up off the base). Thanks.
2- Concrete mix of type A gave more compressive strength than those of type B about (28) MN/m-2. The increase of compressive strength depend on water/cement ratio, type of concrete mix, and the age of concrete in days. 3- Crushed limestone can be used for producing good quality of concrete that was suitable for concrete paving blocks for footpaths,
A typical concrete mix cannot be made without gravel. Concrete is made from a mixture of cement, sand, gravel (crushed stone), and water. A mix ratio of 1 part cement, 2 parts sand, 3 parts gravel, and water, will give you a strong concrete mix. If you subtract the gravel from concrete, you have what's called a mortar mix.

A typical mix for 30 MPa concrete comprises 1 part cement, 2 parts fine aggregate (sand), and 3 parts coarse aggregate (gravel or crushed stone). The water-cement ratio is approximately 0.45-0.50 parts of water per part of cement. This mix results in concrete with a compressive strength of about 30 megapascals (MPa).

Step 2: Choose the appropriate mix ratio for your project based on the desired strength and application. Step 3: Calculate the amount of each ingredient based on the mix ratio and the total volume of concrete. For example, let's say you need to pour 1 cubic meter of concrete using a …
How is the concrete ratio calculated? The concrete ratio is usually calculated differently depending on where and what we will use the concrete for. The so-called classic ratio for cement mix is called the 1-2-3 concrete-mix. This means that the ratio is supposed to be made from 1 part cement powder, 2 parts sand, and 3 parts washed aggregate.

Work it to the Perfect Concrete Mix Ratio. If the mixed concrete looks like the mix in step 9, it''s ready to pour. Otherwise, mix in additional dry mix or water until you get the right consistency. It''s tempting to just squirt water into the dry concrete mix with a hose and mix up a soupy batch of concrete. احصل على السعر WhatsApp

Crusher dust for concrete - Renovate Forum. Jun 12, 2010· Hi, 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 i'm want to use it for footings for raised floor of ganny flat, was going to use mix of 4:1 have used it for chooks pens etc and seems alright but don't …
In most cases the strength is measured at 28 days since concrete usually achieves around 99% of its strength by this time despite the type of concrete mix. Concrete mix/grades are measured by conducting …
Effect of size and type of fine aggregates on flowability of … In total, 103 mortar batches was made with three different sand to cement ratios [s/c] and two different water to cement ratios [w/c] to find out the flowability of mortar and tested using standard flow table.
It may be necessary to vary the amount of ice used per batch, using less in the morning and more as the day grows warmer. This added variation in batching and mixing increases the difficulty of control. The use of ice does effectively accomplish the purpose of cooling the mix in hot weather and is far more effective than cold water.
The mean compressive strength required at a specific age, usually 28 days, determines the nominal water-cement ratio of the mix. The other factor affecting the strength of concrete at a given age and cured at a prescribed temperature is the degree of compaction. ... Determine the percentage of fine aggregate in total aggregate by absolute ...
