Quantities of components should not differ whether we follow weight method or volume method.I understand your question. Hope you find this useful. In general for strength upto 200 kg/cm 2 aggregates upto 40 mm may be used and for strength above 300 kg/cm 2 aggregate upto …
The size of aggeregates comonly used for prepairing different grade of concrete are given below. The calculations and results given in this article are cross verified with different standards and trusted sources like IS456, IS10262 and government’s Rate of Analysis.Based on strength, concrete is classified into different grades like M5, M7.5, M10, M15, M20 etc. *As I have explained above, while calculating M7.5 and M5 grade concrete, total dry material required for concrete is taken as 1.52 instead of 1.55 and quantity of sand and aggregate is adjusted for M10 and M5 based on experience. Maybe 1:3:5 is a good ratio. Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength in concrete. mix above m25 should be designed with code book.What is the size of the box use for measuring aggregates for volume mixingSir, how do I calculated or determine the quantity of materials required per cubic meter by weight to create a concrete mix? The bulk density of frequently used cement varieties (both PPC and OPC) is 1440 kg/cu.m.Hence 8 bags of cement required to prepare one cubic meter of M20 grade concrete.Suppliers sell sand and coarse aggregate in the measurement of Cubic Feet (CFT), UNITS and in lorry or tipper LOADS. Added an answer on July 24, 2020 at 6:07 pm Generally the 9.5-37.5 mm diameter range aggregate are used in RCC concrete work. M20 M15 etc. Yes, the ratio is good as long as the spans are not too long. Concrete are used for different purpose like foundation, pavement etc. The cushion should be provided because the volume is not absolute like weight it differs based on compaction, grading and moisture content of the aggregate.
For example foundation, PCC M7.5 and M10 are used but for floor slab only grade above M20 should be used.We want to know,howcalculate water in m20 grade concreting.Weight to volume ratio of SAND AND AGGREGATE are different in different grades i.e. It gives a good in-depth knowledge to any common man.Can you please explain how to calculate the quantity of brick work and block work..? Thank, you.Thank you very much Aminu. With corrected proportions three concrete cubes are cast and tested for 28 days compressive strength. Though they both have the same Grade name, nominal mix concrete is usually designed for higher strength then mix design concrete. If u need reliable excel formate data contact me on FB Id vishv Dev bhagathow to calculate quantity of water required to make concrete ?What is weight of fine & coarse aggregate and weight of cement in kg for nominal cement concrete mix 1:1:21:1:2 is considered as a nominal mix ratio for m25 but its wrong. If queering time too is provided, it could have been greatReally appreciate what u have done for the fresher’s engineers thanks for each word u wroteFor a concrete slab with a dimension of 15m by 12m and 0.15m thickness, mix ratio 1:2:4, how do I know the amount of cement, sand, aggregate and water require for the concrete.How to know that what mix we have to consider for any kind of construction like road, duplex , 22 story building etc?For Road M 10, M 15 concrete may be used. As per IS456, for 50kg bag of cement you will need 480 kg of total aggregate i.e., 160kg of sand and 320kg of coarse aggregate.i think its 450kg for total aggregate , so 150kg sand and 300kg CAYes that’s what code book suggests If you are looking for weigh batchingIs this method also applicable for designing nominal mixture of M15 gradeYes of course but instead of multiply 1.5 in the volume required formula, you should multiply 1.55.how can i calculate sand and aggregate per cum in kilogramHow can weight calaculate sand and aggregate per cumSince many readers are asking the same question I have updated the post. the specifications are:There is no nominal mix ratio for m25 grade. 3. Fine aggregates = (757.28 x 0.016878) kg/m 3 = 12.78 kg. This is due to the fact that while designing nominal mix concrete we don’t consider various factors like the type of sand and “compactness” of sand and, presence of moisture absorbtion. If you don’t want learn the calculations you can use the quantities given in the table at the end of each topic to produce different grades of concrete. {{#message}}{{{message}}}{{/message}}{{^message}}It appears your submission was successful.
