Sentence examples for aggregates grain from inspiring English sources

Microscope images were grouped as intergranular properties (shape of grains, shape of grain aggregates, grain boundary type and pressure solution), intragranular properties (twinning and alteration) and deformation.

The influence in tile/mortar bond strength of moisture content of tiles, mortars aggregates grain size distribution and nature, binder/aggregate ratio, different tile ceramic parts, water absorption and porous characteristics of historic tiles and new mortars were evaluated.

A specific test was designed in which each type of aggregate was exposed to several times of mixing to evaluate possible changes to the grading curves and in the surface of the aggregates grains.

General solutions are derived for an arbitrary convex-shaped aggregate grain for both two- and three-dimensional cases.

The results show that the values of GF decrease substantially with increasing coarseness of aggregate grain structure, λ.

It was found that with an increase of maximum aggregate grain size in concrete, the values of arithmetical mean height (Sa), the root mean square height (Sq) and skewness (Ssk) for the shotblasted surface also increase, while the value of the kurtosis (Sku) grows for ground surfaces and decreases for the shotblasted surface.

As main results, it can be stated that the bond strength values are directly related to the adherence extension (effective adherence surface) measured at mesoscopic scale and that the greatest influence on bond was exerted by the aggregate grain size and shape.

k ψ is the parameter which depends on the rotations of the slab around the support region outside the critical shear crack ψ (in radians), and calculated as k_{psi } = frac{1}{{1.5 + 0.9 cdot psi cdot d cdot k_{dg} }} - 1 le 0.6 (8)with factor k dg (effect of the maximum aggregate grain size d g ) defined as k dg  = 32/(16 + d g ) ≥ 0.75.

Given the relatively poor aggregate grain harvest of the major exporting countries in 2007, mainly reflecting adverse weather in parts of the EU and in Australia, combined with strong demand in domestic markets and for exports, the ratio of their aggregate cereal supplies compared to normal market requirements in 2007/08 is estimated to remain at a relatively low level of 117percentt.

Uniformly distributed channels between the aggregated grains provide shorter path ways to enhance coloration efficiency.
