1) bulk specific gravity of coarse aggregate 集料毛体积相对密度2) gross volume relative density 毛体积相对密度 1. This paper analysis the effect of coarse aggregate drying quality on gross volume relative density measurement and the best asphalt content of asphalt mixture,then proposes measures ...
aThe fine aggregate met the ASTM C 336 requirements. Its bulk and saturated surface dry specific gravity, absorption, and fineness modulus were 2.75 and 2.78, 0.8%, and 3.0, respectively. The coarse aggregate 细颗粒聚合体符合了ASTM C 336要求。 它的大块和饱和的表面干燥比重、吸收和精致模数分别为...
Variation in bulk density is attributable to the relative proportion and specific gravity of solid organic and inorganic particles and to the porosity of the soil. Most mineral soils have bulk densities between 1.0 and 2.0 g cm−3 [1]. They also mentioned that a very compacted soil perhaps ...
Application: Our colored sand are widely used in architectural decoration, terrazzo aggregate, stone paint, building coating etc. Natural color sand can be used in the manufacturer of marble, floor tile, ceramic tile and decorative sanitary ware and so on, it is glossy, smooth,...
The results of multi regression analysis indicated that air voids and nominal maximum aggregate size significantly affect the permeability, but aggregate gradation does not.;Comparing the permeability data from field cores and laboratory compacted pills, it is clear cores have higher permeability than ...
The extent of interaction between nanoparticles and surfactants was estimated from the hydrodynamic nano-aggregate sizes and zeta potential values. The foam microscopic images and the bubble morphology were examined to elucidate the mechanisms of foam stabilization by nanoparticles. Results clearly showed ...
• Stack of flakes: Coherent particle consisting of a number of aligned lamellae. • Aggregate: Coherent group of stacks. • Clay gel: Coherent network of aggregates. • Void, pore: Open or filled space in clay gel or between ballast grains. • External voids: Open or filled space...
Short chain hydrocarbons have higher destabilizing effect on foams because they have smaller molecular elements which make it more probable for them to solubilize into the micelle aggregates. Lobo et al. [55] have shown that solubilization of oil in the micelles result in an increase in the van...
