Gravel 12 to 10mm and sand is kept in the ratio of 2 1 Cement content depends on the blocks strength requirement, again dependent on whether it s hollow or sol For solid blocks, using 53 grade cement and w/c of 035, one should get between to 20 to 25N/sqmm, using 220 kg cement...

FULLER S RULE states mixing of a total of 42 volumes of cement, sand and gravel will produce a 27 volumes of concrete The unit for this one is in cubic foot Conversion of 10 meter = 3281 ft, hence 42/27cuft x 3281ft/m 3=5494 or rounded off to a good number of 55...

How much cement and sand do i need for a 7 sq metres shed base I want to do a shed base of 7 sq metres and 4 deep How much cement and sand do i need?? How do I work out how much sand and cement I will need for rendering 100 square metr It is 100 square Metres roughly How much sand and cement do I need to lay 150 concrete blocks making 4 ....

How to Calculate Water Cement Ratio For example, if the w/c ratio is 050 for concrete and cement is added is about 50 kg weight of 1 bag of cement Water required for concrete will be, Water/ cement = 050 Water = 050 x 50 Water = 25 liters = 660 gallon...

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...

Two Concrete Calculator are provided for different concrete mixes General mix - 1 5 cement all-in ballast or 1 2 189 3 189 cement sharp sand gravel and Paving mix - 1 3 189 cement all-in ballast or 1 1 189 2 189 cement sharp sand gravel Comment If you are wondering how 1 2 189 3 189 equals 1 5 shouldn t it be 1 6 I hear someone say , the answer is ....

The ratio of cement mortar is 1 5 The sum is 1 5 =6 Thus, the total dry mortar required for 1 cum brick masonry is30cum So, The required cement is 30 1 /6= 005 cum After converting into KG=05 1440=72KG When converted KG into the number of bags= 72/50=144bag To calculate the sand quantity Given that the sand cement ratio is 1 5...

For estimating purposes, you can make about 1 cubic yard of concrete with 5 1/2 94-pound bags of cement, 17 cubic feet of sand, and 18 cubic feet of gravel It takes about forty 80-pound bags of prepackaged materials like Quikrete to ,...

08-11-2021 0183 32 Specifically, this ratio calls for 1 part cement powder, 3 parts sand, and 3 parts aggregate These can then be mixed with a minimal amount of water to achieve a workable, reliable slump 4,000 psi Concrete Mix Ratio Next up, this ratio requires slightly less of one ingredient compared to its predecessor...

Determination of appropriate mix ratios for concrete grades , Kazeem ADEWOLE, Wasiu O AJAGBE, Idris A ARASI 82 Industrial Standards for cement, NIS 444-1 2003 14 From 2003 till date, Portland-limestone cement is the only bagged cement in the Nigerian open market Concrete grades or strength classes are specified in terms of the minimum 150 mm...

Answer 1 of 4 Gravel 12 to 10mm and sand is kept in the ratio of 2 1 Cement content depends on the blocks strength requirement, again dependent on whether it s hollow or sol For solid blocks, using 53 grade cement and w/c of 035, one should get between to 20 to 25N/sqmm, using 220 kg ce....

Considering water/cement W/C ratio of 055 We can also arrive at the Water required = 50 055 = 275 kg So, One bag of cement 50 Kgs has to be mixed with 115 kgs of Sand, 209 Kgs of aggregate and 275 kgs of water to produce M20 grade concrete...

Total weight of concrete ingredients = 50 115 209 275 = 4015 say 400 kg Density of concrete = 2400 kg/cum So, 1 bag of cement produces = 400/2400 = 0167 cum No of bags required for 01 cum of concrete = 1/0167 = 598 bags 6 bags From above, if the concrete mix is 1 2 4 , to get a cubic meter of concrete we require 1Cement = 6 bags ....

Re Which cement to use and what ratio to mix for making pots Any sand and cement mix will work well, just add enough water to get the consistency you need to work it how you want to You could use a concrete mix cement, sand and gravel and the finished product will be stronger the gravel acts like reinforcement, similar idea to glass ....

12-07-2017 0183 32 A ratio of 1 2 4 gives 7 parts Cement is 1 part therefore 1/7 of 2400 = 342kg = 68 x 50kg bags , is 2 head pans,it means that 1 bag of cement will be for 4 head pans and 8 head pans of gravel,therefore for 6bag of cement will require 24 head pan Ie 6 wheelbarrow,nd 48 head pan for gravel Ie 12 wheel barrow Reply...

22-06-2009 0183 32 However, larger projects might require you purchase or rent a portable cement mixer Understanding the Mixing Ratios The first thing you need to know about mixing this material is what the proper ratios are to make a substance capable of supporting 3000 pounds per square inch PSI , that is suitable for most home improvement projects...

In order to answer this question you need to find out how much cement, sand and gravel is needed to make 180kg of concrete mix To do this you must find out how many parts the concrete mix ratio is made up 1 3 5=9 Then divide the total concrete mix 180kg by the number of parts 180/9 = 20...

Concrete mix estimation Our mix-on-site concrete calculation is based on batching by volume Large construction sites employ batching by weight which is more exact You can also estimate the quantity of sand and gravel required by weight Simply multiply the volumetric quantity of sand and gravel with 1400 kg/m 3 bulk density of sand and ....

26-07-2017 0183 32 The ideal mix ratio for blocks for proper strength should be about 1 10 or 1 bag to 25 blocks Step 4 Calculate the total volume of materials required We can therefore estimate the quantity of materials to be purchased If 1 bag of cement is needed for 35 blocks, therefore 86 bags of cement is needed to mould 3000 blocks gotten by 3000/35...

12-11-2014 0183 32 If the ground where you are pouring the concrete mix is good and your mix of 1 cement to 5 of your gravel mix is reasonably accurate you need have no worri In my experience 1 3 would be ridiculous Finish your footings tomorrow and sleep well Yeah the ground is good and firm at the base of the footings Thanks for the advice...

Both of these concrete calculators make an allowance for the fact that material losses volume after being mixed to make concrete Calculator are provided for a general mix and a paving mix, the different ratio of materials are General mix - 1 5 cement all-in ballast or 1 2 189 3 189 cement sharp sand gravel Paving mix - 1 3 189 cement all-in ....

Answer 1 of 2 There is no such specification in INDIaHowever if you want for cement mortar 1 5 one of Cement and five of,sand on volume , the following is the method to calculate the quantity of Cement - Cement mortar 1 5 unit one cum sand - one cum cement-1/5 cum weight of Cement per one....

Another old rule of thumb for mixing concrete is 1 cement 2 sand 3 gravel by volume Mix the dry ingredients and slowly add water until the concrete is workable This mixture may need to be modified depending on the aggregate used to provide a concrete of the right workability The mix should not be too stiff or too sloppy...
