Test jigs were developed to measure the crushing strength of a single pebble at high temperatures (600 and 800 K), as shown in Fig. 1. The test jigs comprise primarily of a T-shaped pushing jigs that ...

The hardened properties of compressive strength at 7, 28, and 91 days as well as pulse velocity, Young's modulus, and surface resistivity were also tested. Based on this study, it is possible to produce SCC with both RCA and FA that has better workability and hardened properties than does RCA and also to reduce the negative effects of the ...

Compressive Strength Formula. The formula to calculate compressive strength is F = P/A, where: F=The compressive strength (MPa) P=Maximum load (or load until failure) to the material (N)

compressive strength was 10 to 20 % lower for concrete with gravel as coarse aggregate as compared to concrete made with limestone and basalt as coarse aggregate. However, in mix with target strength 30 MPa both gravel and basalt showed similar strength. It was concluded that the influence of the type of

This study investigates the compressive behavior of concretes where river or sea pebbles partially (i.e., 33% and 67%) or fully (i.e., ) replace traditional gravel as coarse aggregate, using a noncontact full-field deformation measurement system based on digital …

By changing the grading of pebble and water cement ratio, the influence of pebble grading on the compressive strength and flexural strength of concrete is studied at the same pebble content. Test results show that the compression strength and bending strength of concrete decrease with the increasing of the maximal size of coarse aggregate, while the maximal size (Dmax) of pebble …

Although the larger specimens gave slightly lower strengths, the relation­ ship between aggregate size and strength was the same as for the smaller specimens. Still further tests, involving compressive strength only, were made using a

Mahmoud integrated the discrete element method with image processing technology to model and analyze the modulus, compressive strength, and indirect tensile strength of five aggregates including granite, hard limestone, soft limestone, gravel, and sandstone. The effect of the aggregate strength on the fracture property of the asphalt mixture ...
