Mix Design M-40 Grade
T he mix design M-40 grade f or Pier (Using Admixture – Fosroc) provided here is f or ref erence purpose
only. Actual site conditions vary and thus this should be adjusted as per the location and other f actors.
Parameters for mix design M40
Grade Designation = M-40
Type of cement = O.P.C-43 grade
Brand of cement = Vikram ( Grasim )
Admixture = Fosroc ( Conplast SP 430 G8M )
Fine Aggregate = Z one-II
Sp. Gravity Cement = 3.15
Fine Aggregate = 2.61
Coarse Aggregate (20mm) = 2.65
Coarse Aggregate (10mm) = 2.66
Minimum Cement (As per contract) = 400 kg / m3
Maximum water cement ratio (As per contract) = 0.45
Mix Calculation: -
1. Target Mean Strength = 40 + (5 X 1.65) = 48.25 Mpa
2. Selection of water cement ratio:-
Assume water cement ratio = 0.4
3. Calculation of cement content: -
Assume cement content 400 kg / m3
(As per contract Minimum cement content 400 kg / m3)
4. Calculation of water: -
400 X 0.4 = 160 kg Which is less than 186 kg (As per Table No. 4, IS: 10262)
Hence o.k.
5. Calculation f or C.A. & F.A.: – As per IS : 10262 , Cl. No. 3.5.1
V = [ W + (C/Sc) + (1/p) . (f a/Sfa) ] x (1/1000)
V = [ W + (C/Sc) + {1/(1-p)} . (ca/Sca) ] x (1/1000)
Where
V = absolute volume of f resh concrete, which is equal to gross volume (m3) minus the volume of
entrapped air ,
W = mass of water ( kg ) per m3 of concrete ,
C = mass of cement ( kg ) per m3 of concrete ,
Sc = specif ic gravity of cement,
(p) = Ratio of f ine aggregate to total aggregate by absolute volume ,
(f a) , (ca) = total mass of f ine aggregate and coarse aggregate (kg) per m3 of
Concrete respectively, and](https://image.slidesharecdn.com/engineeringcivil-com-mixdesignm40grade-130411065539-phpapp02/85/Engineeringcivil-com-mix-design-m40_grade-1-320.jpg)
![Sf a , Sca = specif ic gravities of saturated surf ace dry f ine aggregate and Coarse aggregate respectively.
As per Table No. 3 , IS-10262, f or 20mm maximum size entrapped air is 2% .
Assume F.A. by % of volume of total aggregate = 36.5 %
0.98 = [ 160 + ( 400 / 3.15 ) + ( 1 / 0.365 ) ( Fa / 2.61 )] ( 1 /1000 )
=> Fa = 660.2 kg
Say Fa = 660 kg.
0.98 = [ 160 + ( 400 / 3.15 ) + ( 1 / 0.635 ) ( Ca / 2.655 )] ( 1 /1000 )
=> Ca = 1168.37 kg.
Say Ca = 1168 kg.
Considering 20 mm : 10mm = 0.6 : 0.4
20mm = 701 kg .
10mm = 467 kg .
Hence Mix details per m3
Cement = 400 kg
Water = 160 kg
Fine aggregate = 660 kg
Coarse aggregate 20 mm = 701 kg
Coarse aggregate 10 mm = 467 kg
Admixture = 0.6 % by weight of cement = 2.4 kg.
Recron 3S = 900 gm
Water: cement: F.A.: C.A. = 0.4: 1: 1.65: 2.92
Observation: -
A. Mix was cohesive and homogeneous.
B. Slump = 110mm
C. No. of cube casted = 12 Nos.
7 days average compressive strength = 51.26 MPa.
28 days average compressive strength = 62.96 MPa which is greater than 48.25MPa
Hence the mix is accepted.

Graphs of these properties against bitumen content are used to find the optimum content as the average of the contents for maximum stability, maximum density, and 4% air voids. Calculations of mix properties and an example are provided.

This document discusses concrete mix design methods according to Indian standards. It describes the key steps in mix design as outlined in IS 10262:2009, including determining the target mean strength, selecting the water-cement ratio, calculating water and cement contents, selecting the coarse aggregate volume proportion, and reporting the final mix ratios. The example mix design provided has a water-cement ratio of 0.38, 518 kg of cement and 197 kg of water per cubic meter of concrete, with coarse and fine aggregate volumes of 0.664 m3 and 0.336 m3 respectively.
Concrete mix design
The document discusses the American Concrete Institute (ACI) method for concrete mix design. It begins by defining mix design as selecting ingredients and determining their proportions to produce concrete of minimum strength and durability economically. The method involves collecting data on aggregates and cement, then calculating ingredient proportions to achieve the specified compressive strength of 30 MPa while accounting for absorption and surface moisture properties. The example mix design for a water tank specifies cement at 394 kg/m3, fine aggregate at 819 kg/m3, coarse aggregate at 982 kg/m3, and water at 179 kg/m3.

Bottom ash as a partial replacement of fine aggregate
This document presents research on using bottom ash, a byproduct of coal burning, to replace fine aggregates in concrete. A group of students conducted experiments with 0%, 20%, 40%, and 60% replacement of fine sand with bottom ash. Test results showed compressive strengths of 49.7, 47.8, 43.6, and 41.2 MPa at 28 days, respectively, indicating strength decreases as replacement increases. While bottom ash concrete is weaker, it can replace lower grade concretes. Using bottom ash in this way utilizes a waste product, reduces environmental contamination from ash disposal, and decreases demand for natural sand.
