Simplified Shear Design of Structural Concrete Members

called "aggregate interlock". However, it is now considered more appropriate to use the terminology "interface shear transfer" or "friction" since this action still exists even if crack propagation occurs through the aggregate as it does in high strength concrete where the matrix is …

Improved method to measure the strength and elastic ...

2019-7-6 · The standard methods used to determine the mechanical properties of single aggregate particles have shortcomings. Indeed, methods that are commonly used to measure the strength of irregular particles do not provide their elastic modulus and are also only semi-quantitative. The aim of this work is to determine more accurately both the tensile strength and the elastic modulus of single coarse ...

Aggregates for Concrete

2021-8-9 · natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled

A Novel Method of Crushing Glass Aggregates to Reduce …

2021-8-6 · This study proposed a novel method of crushing glass aggregates to reduce the alkali-silica reaction (ASR). Glass aggregates were crushed while immersed in different calcium bearing solutions. ASR measurement and compressive strength tests of mortars incorporating the glass aggregate were performed to investigate the feasibility of the crushing method. The results indicate that the crushing ...

Methodology for determination of tensile strength of soil ...

1985-2-1 · The crushing force, F'', of an aggregate is determined as follows. The jack, J, is lowered until there is sufficient space between P and U for the aggregate. The aggregate is then placed on P flattest-side down (i.e. in its most stable position). The handle, H, is then turned steadily to raise the jack, J, hence compressing the balance, B.

Modelling size effect on rock aggregates strength using a ...

2020-9-14 · For particles from 25 to 50 mm, strength decreases compared to smaller particles of 15 to 25 mm. Experimentally, this reduction is 18.2% of sigma_ {o}, while numerical Cases A and B result in 7.6 and 23.4%, respectively. Consequently, the assumption on constant cell density to capture size effect is validated in the range of sizes 15 to 50 mm.
