Large Batches of Concrete Mixes. 15 Mpa This is a low-strength concrete mix and is suitable for house foundations that are not reinforced, and for boundary walls and freestanding retaining walls.. To make 1 cubic metre of 15 Mpa concrete you will need to mix 5 1/2 bags of cement with 0,75 cubic metres of sand and 0,75 cubic metres of stone.

ACI Mix Design Example

A concrete mix is to be designed for use in a 250 mm (10 inch) thick JPCP pavement. The desired properties are: Slump = 25 mm (1.0 inch) Average 28-day flexural strength of at least 4.5 MPa (650 psi); Coarse aggregate: nominal maximum size = 37.5 mm (1.5 inch), dry-rodded weight = 1600 kg/m 3 (100 lb/ft 3), specific gravity = 2

Section 2: Concrete Mix Design

The concrete mix design is performed to ensure that the concrete mix formulation meets or exceeds the specification requirements. The mix design is used to establish the proper proportioning of components (hydraulic cement, aggregates, water, pozzolans, and admixtures) in the mixture to achieve the specified properties.

A Statistical Approach to Optimizing Concrete Mixture

A step-by-step statistical approach is proposed to obtain optimum proportioning of concrete mixtures using the data obtained through a statistically planned experimental program. The utility of the proposed approach for optimizing the design of concrete mixture is illustrated considering a typical case in which trial mixtures were considered according to a full factorial experiment design

3 MIX DESIGN PROPORTIONING

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.
