Abstract:

Estudio orientado a obtener curvas de referencia de la intensidad del patrón de speckle para verificar los contrastes entre las clasificaciones de suelo: arcilloso, muy arcilloso, limoso, arenoso y medio. Se realizaron normalizaciones utilizando factores de proporcionalidad de concentraciones conocidas de los materiales minerales: arcilla, arena y limo. La aplicación consistió en determinar las clasificaciones y concentraciones de dos muestras ocultas a partir de los promedios de intensidad catalogados. Para la recolección y el análisis de datos se utilizó la metodología de speckle. Las intensidades de las clasificaciones limoso (0.429±0.017), muy arcilloso (0.498±0.019), arcilloso (0.506±0.021), arenoso (0.518±0.021) y medio (0.528±0.022) muestran una buena precisión respecto a la metodología.

Sieve Analysis and Grading Curves

Sieve Analysis and Grading Curves

Sieve analysis is a method used to determine the particle size distribution of aggregate materials. This process involves the following steps:

Fineness Modulus

Fineness Modulus

The fineness modulus (FM) of aggregate is a numerical index that measures the coarseness or fineness of the particles. It is calculated by adding the cumulative percentages of aggregate retained on each of a specified series of sieves and dividing the sum by 100.
Consider performing sieve analysis on sand through a set of ASTM sieves. The weight of aggregate retained in each sieve and pan placed at the bottom is recorded, as given in Column B of Table 1.
To determine the fineness modulus of...

Specific Gravity of Aggregate

Specific Gravity of Aggregate

Aggregates typically contain pores, which can be either permeable or impermeable. Considering the pores in the aggregates, the specific gravity of aggregates is defined in three different forms, namely, bulk or gross specific gravity, apparent specific gravity, and absolute specific gravity.
Bulk or gross specific gravity is calculated by taking the ratio of the mass of aggregates in the saturated surface-dry state to the total volume that includes both the solids and the voids within the...

Design Example: Aggregate Gradation

Design Example: Aggregate Gradation

The right type and quality of aggregates are crucial for concrete as they significantly influence its properties, mix proportions, and cost-effectiveness. If different sources are available for sand, the commonly used fine aggregate in concrete, the selection of sand is primarily based on its gradation.
The grading, or particle-size distribution, of sand is determined using sieve analysis, with standard sizes ranging from 150 μm to 10 mm (ASTM No. 100 sieve to 3⁄8 in. sieve). Sand is sampled...
