    addresses mix designs for concrete paving mixes. SeeFM 5-428 for information on mix designs for structural concrete. CRITERIA 10-1. The flexural (beam) and compressive strengths of a hardened mix are used for the concrete's design criteria. Flexural strength measures the bridging capacity and is used to design nonreinforced concrete pavement.

    Aggregate in Concrete - The Concrete Network

    Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good quality, durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete, with mix adjustments made, as needed.

    20-04-2018· The characteristics of the aggregates influence the properties of the concrete. Weak, friable, or laminated aggregate particles are undesirable. Aggregates containing natural shale or shale like particles, soft and porous particles, and certain types of chert should be especially avoided since they have poor resistance to weathering.

    Ready Mix Concrete Ordering Tips. One of the most important factors before ordering ready-mix concrete is knowing the required compressive strength.Typically, reinforced concrete ranging between 3,500 to 4,000 psi is used on footing and slabs on grade; between 3,500 to 5,000 psi on suspended slabs, beams and girders; and walls and columns normally require between 3,000 to 5,000 psi.

    Mix design of high-performance concrete

    ABSTRACT. A mix design procedure for high-performance concrete mixes has been presented in this paper. Since rheological parameters and compressive strength are fundamental properties of concrete in two different stages of production, the correlation between rheological parameters and compressive strength has been used instead of using water-cement ratio versus compressive strength relationship.

    11-08-2018· When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete.
