May 17, 2017· Concrete Mix Design:-Concrete is a composite mixture which consists of Cement, Sand and Aggregate. Concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength. Accurate concrete mix design makes concrete construction economical.
May 11, 2013· Current method of mix design of concrete is that revised by Dept. of environment (UK) in 1988. British Method recognizes the durability requirements of mix selection. The design is applicable to normal weight concrete made with Portland Cement only or Blast furnace slag/fly ash.
We use different grades of concrete for different parts of the building. We could say the grade of concrete is the only thing we do care lot while concreting. In this post, we are going to explain that in detail. Grades of Concrete Actually, what do we mean by grade of concrete.? Concrete grades are […]
BRITISH Mix design methods were cast and tested for the respective properties after a curing period of 7,28 and 56 days. For each curing age a set of three samples of each type was cast. In all cases the cement content and water/cement ratio was fixed, it was only proportioning of aggregates that were altered as per mix design methods,
specifically developed for concrete pavements, the DOE method is applicable to concrete for most purposes, including roads. Since DOE method presently is the standard British method of concrete mix design, the procedure involved in this method is described instead of out dated Road Note No 4 method.
ACI METHOD OF PROPORTIONING CONCRETE MIXES The ACI Standard 211.1 is a "Recommended Practice for Selecting Proportions for Concrete". The procedure is as follows: Step 1. Choice of slump Step 2. Choice of maximum size of aggregate Step 3. Estimation of mixing water and air content Step 4. Selection of water/cement ratio Step 5.

1 BS - CONCRETE MIX DESIGN (DOE) DOE METHOD OF CONCRETE MIX DESIGN: The British method of concrete mix design, popularly referred to as the "DOE method", is used in the United Kingdom and other parts of the world and has a long established record.
An example of proportioning a mix design through use of this form is detailed in Table 3.1. The contractor establishes the initial parameters for a mix design and serves as the starting point for subsequent proportioning calculations. The initial step in proportioning the mix design is to calculate the water content per cubic yard of concrete.
2/21 2. Designed Mix 2.1 Variability of Strength Design is based on the assumption of certain minimum properties of concrete, such as strength. Actual strength of the concrete produced is a variable quantity. Source of variability include variations in mix ingredients, changes in concrete making and placing; variations also occur in sampling procedure and testing.
