size of aggregate used in m20 concrete

please suggest at the earliest. May I know is it good?Contractors usually add extra sand to reduce the cement content and also to increase the workability(consistency) of concrete.
Would appreciate your quick feedback. One UNIT measurement is equal to 100 cubic feet.

2. Read the post again or sir I’m kathavarayan BE civil Engineer Steels calucaled I need sieI will publish about steel calculation soon. So, 1. weight to volume ratio WILL differ as any nominal ratio prescribed are only approximation as stated in code books for the reason mentioned above. To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. Sir int his case we did calculate sand and aggregate in cubic feet but how we cn use it at site in execution plz tell me quicklyYou can calculate by counting head Pan.
For ease of compaction and workability sometimes on site 10-15 mm aggregate are used. A larger size, 40mm, is more common in mass concrete. The general ratio of fine aggregate to coarse aggregate is 1:2, but it can be adjusted between 1:1.5 to 1:2.5 based on the grading of fine aggregate and size of coarse aggregate.For design mix concrete water content is calculated from Wate/Cement ratio which depends on various factors like the weight of cement, workability etc. Though they both have the same Grade name, nominal mix concrete is usually designed for higher strength then mix design concrete.

Thank, you.Thank you very much Aminu. Sand is confirmed to Zone II – average grading. Are you asking for the calculation for M10 grade concrete?Thats a lot of question. Proper calculation and relative proportioning of materials are very important to produce cost-effective good quality of concrete. If you are using M15 grade concrete then for every 1 pan of cement use 2 pan of fine aggregate and 4 pan of coarse aggregate.1:3:6 is a M10 grade concrete. there is no nominal mix ratio for m25 mix. You will end up using too much sand which is not good for concrete. Typically the most common size of aggregate used in construction is 20mm. Txwe recently engaged in a contract with a builder and he says 1:3:4 ratio for 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. {{#message}}{{{message}}}{{/message}}{{^message}}Your submission failed. It should be washed clearly with the help of non acidic water before use to prepare concrete.The size of aggeregates comonly used for prepairing different grade of concrete are given below. Quantities of components should not differ whether we follow weight method or volume method.I understand your question. However, above concrete mix ratios may not be accurately followed in the construction site.

Once u will create u can see any quantity of M grade of material. 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. With corrected proportions three concrete cubes are cast and tested for 28 days compressive strength. IS456 Codebook recommends the following quantities of total aggregate per 50kg bag of cement to produce nominal mix concrete. 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. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Copyright © 2020 Civil RnD — Ascension WordPress theme by “Calculate Cement Sand & Aggregate – M20, M15, M10, M5 Ratio” M20 (1 cement :1.5 sand :3 stone/brick aggregate). But Maximum size of aggregate generally on site used are 4 0 mm. 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..? he says he normally do this for 2 floor buildings. the specifications are:There is no nominal mix ratio for m25 grade. Prescribed Concrete Mix Ratio of M20 grade concrete is 1:1.5:3 as per codebook. Stone is also known as coarse aggregate. But for nominal mix concrete IS456 codebook suggests the following quantities A much informative and very useful article. If you want accurate proportion and know what you are doing then calculate bulk density of sand and aggregate supplied to your site and tweek the weight proportion ratio to get the volume proportion.

some people will say that m25 grade is 1:1:2 but they are wrong. So, if you are a civil engineer then you must know about the different sizes of aggregate while you design any structure like a building, There are mainly two types of aggregates used by civil engineering construction work to prepare concret. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids.
