Based on the results obtained, the impact of aggregate crushing resistance on the mechanical properties of HPC was assessed. To this end, three properties were analyzed: modulus of elasticity; splitting tensile strength and compressive strength of HPCs in dependency on aggregate crushing resistance (Fig. 5, Fig. 6, Fig. 7).Download : Download high-res image (179KB)

Torsional impact drilling is a new technology which has the advantages of high rock-breaking efficiency and a high rate of penetration (ROP). So far, there is no in-depth understanding of the rock-breaking mechanism for the ROP increase from torsional impact tools. Therefore, it has practical engineering significance to study the rock-breaking mechanism of torsional impact. In this paper

Aggregates constitute 60 – 80% of total concrete constituents. The characteristics of concrete may be affected by the sources from which the aggregate was obtained. The effects of granite sourced from four selected locations within Ogbomoso, Nigeria; on the fresh and hardened properties of concrete were investigated. The granites were obtained from: Asafa (80 4.681 N and 40 20.781 E), Ola

compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2.

Compressive strength test. This test is vital for evaluating the stone’s resistance to crushing loads. A wall stone has to bear the compressive load of the stone’s weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in.

The maximum aggregate impact and crushing values are 20% when the aggregate is to be used in heavy-duty concrete floor finishes, 30% for pavement wearing surfaces and 45% for other concrete works [10, 13]. The lower the value of AIV and ACV, the stronger the aggregate i.e. the greater its ability to resist impact and crushing.
