All the above mixes yield an amount of concrete slightly more than the quantity of coarse aggregate in the mix. CONCRETE MIX WITH AIR 25 MPa, 30 MPa, 35 MPa or 40 MPa DESCRIPTION: CONCRETE MIX WITH AIR is a pre-blended mix of fine and coarse aggregate and Type 10 Portland cement packaged in 30 kg sacks and in one cubic yard (.76 m3) bulk bags. Cement. 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. To obtain good strength, it is necessary to use the lowest possible w/c ratio which affects the workability of the mix. Basic requirements for designing concrete mix ratios: Meet the strength grade of concrete design. Quantities per m³ of Concrete Contact Us | This concrete mixture ratio of 1 part cement, 1 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 2500 to 3000 psi.. Mixing water with this cement, sand, and aggregate will form a paste that will bind the materials together until the mix hardens. Required Data2. High-strength (30 MPa) concrete is suitable for reinforced concrete members and precast items such as concrete flagstones. In high performance concrete, adequate early-age and high later - age strengths can be achieved with proper selection of the mixture proportions quantity and quality. Large Batches of Concrete Mixes. Use the concrete for whatever application is engineered to require a strength of 32 MPa. Hence, an attempt is made to keep the “Water Cement Ratio” as low as possible to obtain a strong, dense concrete-mix.
