The primary objective of this study is to investigate the effects of cylinder size (150 by 300 mm and 100 by 200 mm) on empirical equations that relate static elastic moduli and compressive strength and static and dynamic elastic moduli of concrete. For the purposes, two sets of one hundred and twenty concrete cylinders, 150 by 300 mm and 100 by 200 mm, were prepared from three

Compressive strength and MOE values for concrete specimens are shown in Fig. 9. Mixture proportions (w/cm/s/ CA) were 0.51/1.00/2.63/2.04. Mixtures with CNTs had 0.1% CNTs by weight of cement. The compressive strength of the control concrete mixture was found to be 45.9 MPa (6660 psi), while the compressive strength of the concrete

The coarse aggregate type employed in the study was crushed granite. The compressive strength and abrasion resistance of concretes were tested between at ages 7 to 70 days and 100500 revolutions of abrasion wheels respectively. The study revealed that the compressive strength and abrasion resistance had the optimal performance when the

To achieve high strength, it is necessary to use lowest possible water-cement ratio, which invariably affects the workability of the mix and

Nov 06, 2016 · Compressive strength test was carried out on five concrete cubes with grades of M5, M10, M15, M20, M25. The grain size distribution curve as well as C u (9.88) and C c (0.671) values reveal that the Maddhapara granite dust is classified as well graded sand that can be enhanced high compressibility and shear strength.

lesser compressive strength in the matrix than irregular aggregates with rough surface texture. They were also of the opinion that a fine coating of impurities such as silt on the aggregate surface could hinder the development of a good bond and thus affects the strength of concrete produced with the aggregates.
