  • The Effect of Maximum Coarse Aggregate Size on the ...

    In a study to assess the effect of size of aggregate in higher grade concrete using high volume fly ash, Bhikshma and Florence (2013) found that aggregate sizes influence its strength and that maximum size of coarse aggregate of 12.5 mm gave the highest compressive strength, splitting tensile strength and flexural strength.

  • Effects of Aggregate Size on Properties of Concrete

    Research is described supplementing earlier work which indicated a lack of improvement in concrete strength resulting from increased maximum size of aggregate. The more recent program provided a broader range of classes of concrete and test variables for the purpose of checking the degree of applicabiliry of the earlier finding.

  • Effect of Coarse Aggregate Size on Shear Behavior of Beams ...

    The effect of aggregate size on the shear behavior of reinforced concrete (RC) beams without shear reinforcement was experimentally investigated in this study. Beams with four coarse maximum aggregate sizes were manufactured and tested to shear failure, including 10, 20, 31.5, and 40 mm (0.39, 0.79, 1.24, and 1.58 in.).

    It is further found that the simplified method can accurately predict the effects of reasing the maximum aggregate size on the beam-shear behavior of lightly reinforced concrete members. It is concluded that shear design methods should account for the fact that aggregate interlock plays a critical role in the beam-shear behavior of reinforced ...

  • HOW TO DECIDE MAXIMUM SIZE OF COARSE AGGREGATE TO

    23/3/2015  In a mass concrete work the use of larger size aggregate will be useful due to the lesser consumption of cement. This will also reduce the heat of hydration and the corresponding thermal stresses and shrinkage cracks. But in practice the size of aggregate cannot be increased to any limit on account of the limitation in the mixing, handling and ...

    The purpose of this research was to determine the effects of aggregate size and gradation on the unit weight, strength, porosity, and permeability of pervious concrete mixtures. The water-cement ratio (w/c) and cement-aggregate ratio (c/a) were kept constant at 0.29 and 0.22, respectively, with a design unit weight of 2002 kg/m3(125 lb/ft3).

    Two general rules are that the maximum size should be no more than 3/4 the size of the space between the reinforcing bars, and 1/5 of the smallest form dimension. Finally, it should be noted that as the maximum aggregate size increases, the size and robustness of the mixers, pumps, and other equipment needed to make and place the concrete also ...
