  • The Effect of Aggregate Properties on Concrete

    The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete. Although aggregate is considered inert filler, it is a necessary component that defines the concrete's thermal and elastic properties

  • Concrete Calculator

    Concrete is a material comprised of a number of coarse aggregates (particulate materials such as sand, gravel, crushed stone, and slag) bonded with cement. Cement is a substance that is used to bind materials, such as aggregate, by adhering to said materials, then hardening over time. While there are many types of cement, Portland cement is the most commonly used cement, and is an ingredient

  • Construction of Concrete Canoe using Light Weight Aggregates

    weight concrete was put in the market as a newly emerged building material. The density of light weight concrete falls between 1140 to 1840 kg/m3 and it depends on the relative density of light weight aggregates[2]. The reduced density of light weight concrete is achieved by using aggregates such as expanded clay, perlite, vermiculite, EPS beads etc[3,4,5]. The usage of light weight aggregates

  • Classification of Aggregates - Pennsylvania State

    Heavyweight concrete contains aggregates that are natural or synthetic which typically weigh more than 2,080 kg/m 3 and can range up to 4,485 kg/m 3. Heavy weight aggregate is most commonly used for radiation shielding, counterweights and other applications where a high mass-to-volume ratio is desired. ASTM C637 covers aggregates used for radiation shielding and Table (3) contains the physical
