Characterization of pre-treated drill cutting waste and its use as fine aggregate in concrete

Drill cuttings, generated in oil well drilling are managed to be disposed but will always have many environmental impacts. The innovation of this study was not only to produce a new and cost-effective material from drill cuttings, but also to mitigate its negative environmental impacts. Therefore, this article aims at characterizing and assessing behavior of drill cutting (DCI) deriving from well drilling activities in...

Spatial analysis of soil physical attributes from a degraded area under different types of management

The objective of this work was to analyze the spatial variability of soil aggregates, porosity and density under five different land-uses and management conditions (degraded substrate - SD; degraded substrate with sewage sludge and Eucalyptus crop - SDLE; soil under pasture SP; capoeira under regeneration - SR; and soil under cerrado - SC). Total porosity (m3.m-3) and density (Mg m-3) of the soil; the mean weight...
