Apr 08, 2014· IS-10262-2009-CONCRETE MIX DESIGN – INDIAN STANDARD METHOD. The following points should be remembered before proportioning a concrete mix a per IS-10262-2009. This method of concrete mix proportioning is applicable only for ordinary and standard concrete grades. The air content in concrete is considered as nil.
BS 8500. BS 8500 is the British Standard for specifying and producing concrete. It is the complementary British Standard to BS EN 206. BS 8500 is split into two parts. Part 1 covers specification and gives guidance to the specifier. Part 2 covers the constituent materials in concrete and contains the information required by the concrete producer.

The DOE method was first published in 1975 and revised in 1988. The DOE method of mix design is applicable to all types of concrete mixes including roads, while Road Note No. 4 was applicable to roads and air fields only. This method can also be used for concrete containing fly ash. DOE method is a standard method of mix design in U.K. now.
14-Proportion of gradients per trial mix (SSD) of : 0.0083m3 (For small mixer) Cement = 3.7 kg Water = 1.7 kg Fine aggregate = 5.8 kg Coarse aggregate = 8.4 kg This trial will make about 20 kg of concrete; enough for slump and Vebe tests. 15-Miscellaneous Material Cement Water Coarse agg. Fine agg.
May 17, 2017· Mix Design (M) = Cement: Sand :Aggregate As per BS 8500-2 British/European standards The grade of concrete is denoted as C10, C15, C20,C25, etc., 'C' which means ' Concrete Strength class' and number behind C refers to characteristic Compressive strength of Concrete …
A concrete mix design should focus on three key issues: 1). Does the mix meet the performance requirements of the specifications with respect to strength and other characteristics such as shrinkage, permeability, w/cm ratio, etc.? 2). Is the trial batch …
For the design of slabs-on-ground with fiber reinforcement, ACI 360R Chapter 11 provides detailed information and calculations. The load capacity of a slab-on-ground is a function of its thickness, the subgrade modulus and the interaction between the slab and the subgrade. Based on a realistic assumption that concrete
Jul 09, 2017· The mix design M-40 grade for Pier (Using Admixture – Fosroc) provided here is for reference purpose only. Actual site conditions vary and thus this should be adjusted as per the location and other factors. Parameters for mix design M40 Grade Designation = M-40 Type of cement = O.P.C-43 grade Brand of cement = Vikram […]
Mix Design of Concrete is the process of determining the right proportions of cement, sand, and aggregates for concrete to achieve the target strength of concrete. The Advantage of concrete mix design is that it gives the right proportions of materials, thus making the concrete use economical in achieving the required strength of structural ...
As per British standard, different types of concrete grade are normal grade of concrete like C10, C15 & C20 and C25 are prepared according to their nominal mix ratio and standard grade of concrete and higher strength concrete grade like C30, C35, C40, C45, C50, C55, C60, C65, & C70 are prepared according to their design mix.
Procedure for concrete mix design calculation as per IS 10262-2009 based on strength and durability, workability, economy is discussed in this article. To produce concrete of required strength and properties, selection of ingredients and their quantity is to be …
A popular simplified mix design method is that from BRE. Compressive strength is, in general, related to durability. The greater the strength the more durable the concrete. To satisfy the required compressive strength, a value for water/cement (w/c) ratio is estimated for an appropriate test age (generally 28 days) and cement type.
