The ratio of fine to coarse aggregate is chosen as usual as 1:2. From the above table we know we need 250kg of total dry aggregate for our 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. Sand = 1 Part
Max. Agg. Size of 20 mm a) Water content = 186 Kg/cum b) Sand as percentage of total aggregate by absolute volume = 35 %. Thus, Net water content = 180.42 Kg/cum Net sand percentage = 33 %. 6. DETERMINATION OF CEMENT CONTENT W/c ratio = 0.5 Water content = 180.42 Kg/cum Thus, Cement content = 360.84 Kg/cum Adequate for moderate exposure Say 360 ...
Thanks for A2A.. There is two types of mix for calculating coarse aggregate content. One is design mix and another one is nominal mix. If you want to calculate the c. aggregate content as per design mix, then you can follow IS 10262. For that you ...

May 17, 2017 The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in
Dec 16, 2019 The M20 Grade Concrete comes in a mix ratio of 1:1.5:3.1 cement.1.5 sand and three aggregate. TheM20 stands for the mixture of aggregate, sand, and cement prepared so as the whole cement concrete cube of size becomes 154 cm by 15cm by another 15 cm.
Jun 17, 2020 In the past, the specifications for concrete prescribed the proportions of cement, fine, and coarse aggregates. These mixes of the fixed cement-aggregate ratio which ensures adequate strength are termed nominal mixes. B. IS 456-2000 has designated concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35, and M40. In this ...
aggregate have openings ranging from 150 µm to 9.5 mm (No. 100 sieve to . 3 ⁄ 8. in.). The 13 standard sieves for coarse aggregate have openings ranging from 1.18 mm to 100 mm (0.046 in. to 4 in.). Tolerances for the dimensions of open-ings in sieves are listed in ASTM E 11 (AASHTO M 92). Size numbers (grading sizes) for coarse aggregates
Aug 11, 2018 When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete.

Therefore , Density of aggregate = 1450 – 1750 kg/ m 3 . Quantity of aggregate in cubic feet = 3 x 1.54 /5.5 x 35.3147 = 29.66 cu.ft. Water: For M20, 30 liters of water per 50kg cement . Total amount of water required = 30 x 403.2 / 50 = 241.92 litre. 8.064 bags of cement required for 1 cu.m of M20
Fine aggregate is also known as sand. 2) Coarse aggregate:- The aggregate whose size is greater than 4.75 mm is known as coarse aggregate. Stone is also known as coarse aggregate. The size of aggeregates comonly used for prepairing different grade of concrete are given below.
(Note 1: For every ±0.05 increase or decrease change in w/c, the coarse aggregate proportion is to be changed by 0.01.If the w/c is less than 0.5, volume of coarse aggregate is required to be increased to reduce the fine aggregate content in mix. If water cement ratio is more than 0.5, volume of coarse aggregate is to be reduced to increase the fine aggregate content.
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
Calculations of cement content for mix design of M20 grade concrete. Water content (As per Table 4, page no 5 of IS 10262 ) for 20 mm nominal maximum size of saturated surface dry aggregate is 186 kg per cum ( for 50 mm slump without using superplasticizer).
Coarse aggregate ratios for different Zones of Fine aggregates are given in Table 3 of IS10262. These are ratios are valid for 0.5 Water-cement ratio. Table 3 Volume of coarse aggregate to total aggregate ratio for Mix Design of M20 concrete – IS10262
Proportion of volume of coarse aggregate and fine aggregate . As per clause number 6.2.7 , Table 10 page number 10 of IS 10262 : 2019 . For Zone II 20 mm nominal maximum size aggregate, Volume of coarse aggregate and fine aggregate = 0.66 per unit volume . Hence volume of fine aggregate = 1 – 0.66 = 0.34 per unit volume of total aggregate .

M20. pervious concrete is designed by ACI522R-10 design code. The effect of . w/c ratio and aggregate size on the strength of pervious concrete are . studied. The property o. f pervious concrete by replacing cement by fly . ash is also studied. It is revealed that the compressive strength
used for structural work except foundation is M20 and above. The aggregate size usually used to design the mix is 10mm to 20 mm size. Water cement ratio used is around 0.4 to 0.5 in Industry. So here an attempt is made with aggregates of size 6mm and below which requires more water cement ratio and cement content to obtain the design ...
Concrete Mix Design Calculation : M20, M25, M30, M40 Grade Concrete. ... Size of aggregate should not be more than one-fourth of the minimum thickness of member, mostly 20 mm nominal size aggregate is suitable for most works. It is always suggested to go the maximum nominal size of aggregate to save on quantity of cement per unit of concrete.
