Know MoreA comprehensive series of drained triaxial compression tests were performed on crushed concrete aggregate (CCA) moist as compacted. When compared to ordinary natural well-graded gravelly soils, the peak strength and stiffness increase more significantly with dry density, while the effect of the degree of saturation during compaction is much less significant.

Know MoreThe results obtained from concrete compressive strength test for the samples with glass revealed an improved compressive strength at 7, 14, 21 and 28 days. At 28 days, the compressive strength gave an optimum value of 20.65N/mm 2 at 10% replacement with coarse glass.

Know MoreTo obtain high strength concrete, coarse aggregate size is usually held to a maximum size of 19 mm, but additional cement is required for the additional surface area. The fine aggregate can generally contain less material passing 300 um and 150 um sieve because of the higher cement content.

Know MoreFor concrete with nominal maximum size of aggregate greater than or equal to 1.5 inch [37.5 mm], the preferred minimum core diameter shall be, three times the nominal maximum size of coarse aggregate but it should be at least two times the nominal maximum size of the coarse aggregates.

Know MoreExperiments were conducted to determine the effects of the properties of 13 different coarse aggregates on the flexural and compressive strength of concrete. Depending on the aggregate, differences of 40 percent in flexural strength and 29 percent in compressive strength were obtained for concrete of the same mix proportions.
