# coarse aggregate size in m25 mix

#### Concrete Mix Design Calculation - M20, M25, M30 - Procedure ...

Step 5: Estimation of Coarse Aggregate proportion:-From Table 3 of IS 10262- 2009, For Nominal maximum size of aggregate = 20 mm, Zone of fine aggregate = Zone II. And For w/c = 0.5. Volume of coarse aggregate per unit volume of total aggregate = 0.62. Table for correction in estimation of coarse aggregate proportion

#### Mix design for M25 With Admixtureas per IS Code IS 10262 : 2019

Hence Volume of coarse aggregate and fine aggregate = 1 – 0.105-0.147–0.00083-0.005 = 0.742 cum. 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 ...

#### Concrete Mix Design M-25 - Help The Engineer

the volume of coarse aggregate per unit volume of total aggregate corresponding to 20mm size aggregate and fine aggregate Zone II for the water-cement ratio of 0.43 The volume of coarse aggregate per unit volume of total aggregate is 0.634 Volume of fine aggregate is taken as 0.366 A-5 MIX CALCULATIONS

#### M25 Grade Concrete Mix Design - IS10262 Recent Revision ...

The coarse aggregate ratios for different zones of fine aggregates are given in Table 3 of IS10262. Table 3 Volume of coarse aggregate to total aggregate ratio for Mix Design of M25 concrete – IS10262

#### What is M25 grade concrete ratio in concrete mix design ...

Nominal mix of m25 concrete grade is that generally used for small-scale construction and small residential buildings where the consumption of concrete cement sand and aggregate is not high. Nominal mix ratio of m25 grade of concrete is 1:1:2, mixture of cement, sand, aggregate and water in which one part is cement, one part is sand and two ...

#### Mix design M25 Grade designed as per IS 10262:2009 and IS 456:2000

A-7 PROPORTION OF VOLUME OF COARSE AGGREGATE AND FINE AGGREGATE CONTENT From Table 3 of IS 10262:2009 Volume of coarse aggregate corresponding to 20 mm size aggregate and fine aggregate Zone II for water-cement ratio of 0.50 =0.62 . In the present case water-cement ratio is 0.44.

#### M-25 Mix Designs as per IS-10262-2009 - Civil Engineering

The mix design is for maximum size of aggregate upto 40 mm are readily available.In mass concrete the maximum size of aggregate is considered as 80 mm for M15 and M20.The grading of 80 mm size aggregate is not available .Please provide mix design of A80 M20.

#### HOW TO DECIDE MAXIMUM SIZE OF COARSE AGGREGATE TO BE USED IN ...

On the other hand in smaller size aggregates the surface area is increased which increases w/c ratio and lower strength is achieved. 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 20 mm may be used. Conditions That Decide Maximum Size of Coarse Aggregate to be Used in ...
