Generally 1:2:4 or 1:3:6 mix is used. The measurement of material can be done by weight batching or volume batching. In volume batching, coarse aggregate and sand shall be measured by measuring box of 30cmx30cmx38cm of a suitable size equivalent to one bag cement of 1/30 m 3 or 0.035 m 3. Sand shall be measured on the basis of its dry volume.

Incase you want to convert the requirement of Sand and Aggregate in Cum; 1 Cum = 35.31 Cft Eyeopener:Many popular blogs claim M20 nominal mix as 1:1.5:3 ,however we strongly differ by same.Through this blog,we are also trying to address the same myth which is being carried forward since last 4 decades.. The reason being: With constant research and development in the field of cement …
I would suggest the ratio of 1:2:3 or 1:1.5:3 for M20 grade concrete and 1:2:4 or 1:2.5:3.5 for M15 grade concrete. If you prepare concrete with your ration then the concrete will have too much sand. Too much sand causes shrinkage and this will not give high-density concrete. Hence use 1:2:3 for good strength and 1:2.5:3.5 for moderate strength.

Strength of PCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 (n/mm 2 must be read as 'Newton’s per millimeter Cubic') compressive strength at 28 days. The proportions of materials (cement, sand, coarse aggregate) for nominal mix/design mix concrete that are normally used are 1:3:6 or 1:4:8.

For example, for M30 grade, the mix proportion can be 1:1:2, where 1 is the ratio of cement, 1 is the ratio of sand and 2 is the ratio of coarse aggregate based on volume or weight of materials. The strength measure with concrete cube or cylinders by civil engineers at the construction site.
Resulted show that the increment of limestone microfines amount in MS from 4.3% to 20% by mass increases the compressive and flexural strengths and improves the abrasion resistance of the MS-PCC. The MS-PCC has higher compressive and flexural strengths when the surface roughness of the sand particles is larger and the crushing value is lower.
For instance, C10 has the strength of 10 newtons, C15 has the strength of 15 newtons, C20 has 20 newtons strength and so on. Different mixes (M) come in various mix proportions of the various ingredients of cement, sand and coarse aggregates. For instance, M20 comes in the respective ratio of 1:1:5:3. You can see other examples below in the table.

From above table, we see that, concrete gains 16 percent strength in one day, 40 percent in 3 days, 65% in 7 days, 90% in 14 days and 99% strength in 28 days. Thus, it is clear that concrete gains its strength rapidly in the initial days after casting, i.e. 90% in only 14 days. When, its strength have reached 99% in 28 days, still concrete ...
The most common strength test, compressive strength, is carried out on a 50 mm (2-inch) cement mortar test specimen. The test specimen is subjected to a compressive load (usually from a hydraulic machine) until failure. This loading sequence must take no less than 20 seconds and no more than 80 seconds. Table 2 shows ASTM C 150 compressive ...

Oct 01, 2011· The Chinese national standard of JTG F 30-2003 approves the use of MS in PCC and specifies that the crushing value of MS used in highway PCC should be less than 20–25% by mass and microfines content in MS should be lower than 3–5% by mass, based on the abrasion resistance.
The values of compressive strength ranged between 28.66N/m² to 39.55N/m² up to 28 days of curing, the strength was also observed to increase with hydration period which inform non-deterioration of concrete. The results for the values of flexural strength range between 3.5N/mm² and 6.0N/mm² at 28days of curing.
