Physicochemical Modifications in Geomaterials and Their Leachates Extracted from Acidic Attack

April 17, 2020
Exposure of geomaterials to acid leachates may cause chemical species desorption, mineral dissolution, and metal leaching. This study seeks to understand the changes in the physicochemical composition of liquid extracts resulting from the exposure of four different geomaterials (uniform fine sand, basalt residual soil, kaolin, and bentonite) to a blank solution ...

Spread footings bearing on circular and square cement-stabilized sand layers above weakly bonded residual soil

July 06, 2020

The practice of soil-cement reinforced layers to bear shallow foundations is a feasible option in low bearing capacity soils. This paper addresses the interpretation of plate load tests bearing on compacted artificially cemented sand layers of distinct sizes and shapes (cylindrical and prismatic) overlaying a weakly bonded residual soil stratum. Static ...

Experimental, numerical, and analytical investigation of the effect of compaction-induced stress on the behavior of reinforced soil walls

July 09, 2020
The influence of the compaction-induced stress (CIS) is experimentally, numerically and analytically evaluated on the behavior of reinforced soil walls (RSWs), under working stress conditions. Experimental studies have been carried out to evaluate the effect of the compaction condition at the back of the block facing on the behavior of geosynthetic reinforced so...

Mass movements in the Northeast region of Brazil: a systematic review

July 29, 2020

Mass movements are one of the main causes of loss of people and environmental assets. Several factors contribute to mass movements, such as terrain morphology, rainfall regime, soil properties, land use and occupation. Studies showed that in the Northeast region of Brazil, between the years of 1991 and 2012, 38 events related to mass movements were reco...
