This paper presents the effects of maximum aggregate size on the smart aggregate (SA)-based concrete seismic stress monitoring. Three types of maximum …
The aggregate size plays an important role in the nonlinear mechanical behaviour of concrete, which is strongly related to the size effect. In this study, the meso-mechanical modelling method has been established based on the continuous grading aggregate model to simulate the uniaxial compressive failure behaviour under quasi …
ASTM C 125 defines the maximum aggregate size in one of two ways: Maximum size. The smallest sieve through which 100 percent of the aggregate sample particles pass. Superpave defines the maximum aggregate size as "one sieve larger than the nominal maximum size" (Roberts et al., 1996 [1]). Nominal maximum size. The largest sieve …

Each series was considered to examine the effect of maximum aggregate size on the fracture characteristics of SCC of varying maximum aggregate sizes for two different strength levels, medium strength (M-series represented as GM in Table 1) and high strength (H-series represented as GH in Table 1). For. Analysis of fracture parameters …
Sixteen mixtures to study the effect of the maximum size of coarse aggregate on compressive strength for (high strength concrete). The concrete mixture is completely …
Because maximum aggregate size can impact concrete properties such as shrinkage, and also the cost of concrete, the largest aggregate size consistent with the requirements of 26.4.2.1 should be permitted. With the w/cm fixed, the larger the nominal maximum size of aggregates, the lower the cement content for a given consistency. Or, stated ...
🕑 Reading time: 1 minute Coarse aggregate is one of the essential components of concrete and occupies the largest volume in the mix. That is why it greatly affects the concrete mix design. Its properties such as strength, maximum size, shape, and water absorption influence water demand, the quantity of cement and fine aggregate in […]
Investigation was carried out to study the effects of maximum aggregate size (MAS) of recycled brick coarse aggregate (12.5 mm, 19.0 mm, 25.0 mm, and 37.5 …
Maximum size of aggregate was shown to have a great effect on frost resistance. For example, the 1/4 in. maximum aggregate size specimens showed expansions during freezing, only when the water-cement ratio was as high as 0.60, while 3/4 in. maximum aggregate specimens showed expansions at a water-cement ratio as low as 0.45.
The bond strength remained at the same level with decrease in maximum aggregate size except at maximum aggregate size of 9.53mm when there was a drop in bond strength, despite better compressive and splitting tensile strengths. ...

aggregate size strongly influences the concrete strength. Test results also show that the optimum concrete strength is reached by using aggregates of 9.5mm maximum size.
The purpose of this research was to determine the effects of aggregate size and gradation on the unit weight, strength, porosity, and permeability of pervious concrete mixtures.
Han et al. studied the effects of steel fiber length and the maximum size of the coarse aggregate on mechanical properties of the steel fiber concrete [17]. ey proposed the rational range of the ...

Moreover, the concrete size effect is weakening as the maximum aggregate size increases. Note that, by increasing the maximum aggregate size of the mixture, the aggerate content increases subsequently. This increase is necessary to provide concrete mixtures with similar mechanical properties (e.g., compressive strength and …
In general, a decrease in the maximum coarse aggregate size may have advantages when it comes to concrete compressive strength: "internal weak planes may be less likely to …
